    The decision of the Tax Court is reversed, and the case is
    remanded to that court for further proceedings.
    Comcast contested an Opinion and Order issued by the Director of the
    Department of Revenue, which concluded that the property that Comcast uses
    to provide its cable television and internet access services is subject to central
    assessment by the department. The chief issue was whether either the cable tele-
    vision or the internet access services qualifies as a “data transmission service”
    and thus is a “communication” business or service under the central assessment
    statutes. The Tax Court concluded that Comcast’s internet access service, but not
    its cable television service, is a data transmission service. The Tax Court further
    concluded that Comcast’s cable television service is the primary use of the prop-
    erty that Comcast uses for both services, and therefore none of the property used
    to provide both services is subject to central assessment by the department. Held:
    (1) The legislature intended the phrase “data transmission services,” as used in
    ORS 308.505(2), to have a technical meaning drawn from the telecommunica-
    tions field; (2) a “data transmission service” is a “service[  that provide[s] the
    ]
    means to transmit data from one computer or computer-like device to another
    across a transmission network”; and (3) both Comcast’s cable television and
    internet access services are “data transmission services,” and therefore qualify
    as “communication” businesses or services, making the property that Comcast
    uses for those services subject to central assessment by the department.
    The decision of the Tax Court is reversed, and the case is remanded to that
    court for further proceedings.

    LINDER, J.
    This is a direct appeal from a decision of the Oregon
    Tax Court Regular Division (the Tax Court) setting aside an
    Opinion and Order issued by the Director of the Department
    of Revenue (the department). ORS 305.445. The chief issue
    on appeal is whether either Comcast’s cable television ser-
    vice or internet access service qualifies as “communication”
    under ORS 308.515(1)(h) and is, therefore, subject to central
    assessment by the department pursuant to ORS 308.505 to
    ORS 308.665. Under ORS 308.505(2), “[c]ommunication”
    includes “data transmission services.” In this case, whether
    Comcast’s cable television service or internet access service
    qualifies as a “communication” service or business depends
    on whether either service is a data transmission service.
    The Tax Court concluded that Comcast’s internet
    access service, but not its cable television service, is a data
    transmission service. Comcast Corp. v. Dept. of Rev., 
    20 OTR 319
    , 333, 335 (2011). The Tax Court further concluded that
    Comcast’s cable television service is the primary use of the
    property that Comcast uses for both. 
    Id. at 337
    . Consequently,
    pursuant to ORS 308.510(5), the Tax Court determined that
    the property that Comcast uses for the two services was not
    subject to central assessment for the 2009-2010 tax year,
    contrary to the department’s determination. 
    Id.
     Both par-
    ties appeal. The department contends that both services
    are data transmission services, while Comcast urges that
    neither service is. For the reasons that follow, we hold that
    both the cable television and internet access services qualify
    as data transmission services and are, therefore, commu-
    nication services subject to central assessment under ORS
    308.515(1)(h). Accordingly, we reverse and remand the deci-
    sion of the Tax Court.
    I.  FACTUAL AND PROCEDURAL BACKGROUND
    The following facts and those that we discuss later
    are drawn from the Tax Court opinion, as supplemented
    with additional facts derived from our review of the record.
    Although the parties dispute the conclusions to be drawn
    from the facts, the facts themselves are not significantly
    contested.

    Comcast uses real property, tangible personal prop-
    erty, and intangible personal property to provide three ser-
    vices. Those services are cable television, internet access,
    and “voice over internet protocol” (VOIP).1 The cable tele-
    vision and internet access services both involve, as the Tax
    Court found and Comcast does not dispute, “the commu-
    nication of data.” Comcast Corp., 20 OTR at 320. Many of
    the major tangible, personal, and real properties owned by
    Comcast are used in some way to provide all the services
    that Comcast offers, including the cable television and inter-
    net access services at issue in this appeal.
    As we later describe in additional detail, Comcast’s
    cable television service essentially provides video content
    (television, movies, and other video programming) to cus-
    tomers. The transmitted content or data flows between
    Comcast and its customers predominantly in one direction—
    from Comcast to the customer. Certain interactive features
    cause signals to flow in the opposite direction—from the
    customer to Comcast—as well. Those features mainly facil-
    itate communication back from Comcast to the customer,
    such as transmitting a particular movie to the customer in
    response to the customer’s request for it through Comcast’s
    on-demand video product. For the most part, the content
    transmitted to the customers is either owned by Comcast or
    licensed to Comcast by third parties so that Comcast may
    transmit it to customers. A significant exception is adver-
    tisements, which third parties pay Comcast to transmit
    to Comcast’s customers. The revenue generated from local
    and national advertisers is a “significant part” of Comcast’s
    business, accounting for $1.5 billion of revenue in 2008, for
    instance.
    Comcast’s internet access service, just as the name
    suggests, provides access to the internet. In so doing, the
    internet access service facilitates the flow of content princi-
    pally between the customer and third parties. In contrast to
    its cable television service, Comcast does not own, generate,
    or license that content. Instead, the content, which takes the
    1
    VOIP is effectively telephone service provided via the internet. Comcast
    does not dispute the department’s treatment of the VOIP service as a communi-
    cation service; thus, only the treatment of the cable television and internet access
    services as communication services is at issue in this appeal.

    form of e-mail, documents, video and audio files, and similar
    information, is either generated by Comcast’s customers and
    sent via Comcast’s internet access service to others, or is
    generated by others and accessed by the customer through
    Comcast’s service.
    For both the cable television and the internet access
    services, the content transmitted from Comcast to the cus-
    tomer travels through Comcast’s cable plant. The cable plant
    consists of tangible property in the form of
    “signal receiving, encoding and decoding devices; headends
    and distribution systems; and equipment at or near *  *  *
    customer’s homes. The signal receiving apparatus typi-
    cally includes a tower, antenna, ancillary electronic equip-
    ment and earth stations for reception of satellite signals.
    Headends consist of electronic equipment necessary for
    the reception, amplification and modulation of signals and
    are located near the receiving devices. [The] distribution
    system consists primarily of coaxial and fiber-optic cables,
    lasers, routers, switches, and related electronic equipment.
    [The] cable plants and related equipment generally are
    connected to utility poles under pole rental agreements
    with local public utilities, although in some areas the dis-
    tribution cable is buried in underground ducts or trenches.
    Customer premises equipment (“CPE”) consists primarily
    of set-top boxes and cable modems.”
    Comcast Corp., 2008 Annual SEC Report 16 (2009).
    Until recent years, the department did not consider
    Comcast’s internet and cable services to be subject to central
    assessment. As a result, the property used for the internet
    and cable services was subject to local assessment. When
    those services were locally assessed in 2008, the maximum
    assessed value (MAV) of all Comcast’s tangible property,
    real and personal, owned and used in Oregon, was calcu-
    lated at $434,084,202. Beginning with the 2009-2010 tax
    year, the department treated cable television and internet
    access services as “communication” services or businesses
    and added Comcast, along with 125 other companies, to the
    central assessment roll. As of January 1, 2009, the depart-
    ment calculated the real market value (RMV) and MAV of
    all Comcast’s property, real and personal, owned and used in
    Cite as 
    356 Or 282
     (2014)	287
    Oregon, at $1,135,868,000. That 2009 calculation included
    the value of Comcast’s intangible property, while the previ-
    ous tax year values, which had been calculated through local
    assessment, had not. The addition of the value of Comcast’s
    intangible property as a result of central assessment was,
    in large part, why the assessed value of Comcast’s property
    increased so remarkably in 2009.
    Comcast initiated this action, contesting the Opinion
    and Order issued by the department that centrally assessed
    the property that Comcast uses for its internet access and
    cable television services. The case went to trial before the
    Tax Court. The parties’ arguments to the Tax Court pre-
    sented widely divergent views of the meaning of “data trans-
    mission services” for purposes of ORS 308.505(2). Suffice
    it to say, Comcast argued that “data transmission services”
    meant the kind of private line intracompany data transmis-
    sion services provided in 1973 by point-to-point microwave
    transmissions, which did not include cable television or
    internet access. The department, conversely, urged that the
    legislature used terminology broad enough to include busi-
    nesses and services of all kinds, as long as the service pro-
    vides the means to transmit data to and between the cus-
    tomer and others, which cable television and internet access
    providers (and perhaps many other businesses) do.
    The Tax Court was not satisfied with either party’s
    interpretation. The Tax Court considered the department’s
    interpretation so expansive as to give the department an
    ability to set legislative policy in the guise of interpretation.
    Comcast Corp., 20 OTR at 326-27. To avoid what it thought
    might be the potential unconstitutionality of the statute, the
    Tax Court concluded that the statute should be interpreted
    more narrowly than the department proposed. Id. at 327.
    But the Tax Court also rejected Comcast’s position—which
    restricted the statute to “a particular technological form of
    data transmission” in the form of private line microwave
    service—as too narrow. Id. at 328. The Tax Court reasoned
    that the legislature could have expressly limited the stat-
    ute to that service by using much more tailored terminol-
    ogy; instead, the legislature adopted broader language to
    address prospective technological developments. Id.
    288	                          Comcast Corp. v. Dept. of Rev.
    After rejecting the parties’ positions, the Tax Court
    identified and adopted something of a middle-ground inter-
    pretation. In particular, the Tax Court concluded that, by
    referring to data transmission “services,” as opposed to data
    as a commodity, the statute reached only businesses that,
    for a fee, take data owned or generated by one party and
    move it to another party. Id. at 332. In effect, the Tax Court
    drew a statutory line between companies that are a conduit
    for the data of others and companies that sell the data to the
    customer as well as provide the conduit for it.
    With that interpretation of the statute in place, the
    Tax Court concluded that the cable television service is “not
    a communication business or a data transmission business
    within the meaning of ORS 308.505(2),” because it does not
    transmit data or content created by its customers, nor does it
    transmit, to any significant degree, content to its customers
    from others. Id. at 333. Rather, the cable television service
    principally transmits data (e.g., television programming,
    movies, and special programming by subscription) that
    Comcast itself owns or otherwise has the right to transmit.
    The court reached the opposite conclusion, however, with
    regard to Comcast’s internet access service. The Tax Court
    reasoned that, because the data that flows in the internet
    access service is “not data created by Comcast or data as
    to which [Comcast] has publication rights,” Comcast’s inter-
    net access service is a data transmission service within
    the meaning of ORS 308.505(2). Id. at 335. As noted, both
    parties, dissatisfied with the Tax Court’s resolution of the
    issues, appeal.
    On appeal, neither party defends the Tax Court’s
    ultimate decision or the reasoning that led to it. Instead,
    the parties essentially renew the positions that they
    advanced below. The department contends that the legisla-
    ture intended the phrase “data transmission services” to be
    broadly descriptive of any communication service that uses
    a network to transmit electronic data between computers
    or other devices capable of decoding and using that data.
    Because the legislature also added the words “by whatever
    means provided” to the definition, the department argues, it
    intended that the means of transmission would not be lim-
    ited to any particular technology. As a result, according to
    Cite as 
    356 Or 282
     (2014)	289
    the department, the statute reaches an open-ended class of
    communication services not restricted to a specific technol-
    ogy or to the particular way that technology was used or
    applied as of 1973.
    Comcast’s interpretation lands at the opposite end
    of the spectrum. Comcast maintains that the legislature
    amended the statute in response to plans by entrepreneurs to
    construct a point-to-point (also termed “private line”) micro-
    wave communication network along the west coast, including
    through Oregon. According to Comcast, “data transmission
    services” was added to the statute to describe the particu-
    lar service that was prompting the expansion of the point-
    to-point microwave infrastructure—specifically, “intracom-
    pany” communication of business data. Through that service,
    a company could, for a fee, obtain a private line by which the
    company could send data between its own geographically dis-
    tant offices and branches; the company could not, however,
    use that line to exchange data with outside entities or third
    parties. Comcast agrees that the legislature did not intend
    to limit the statute’s reach to any particular technology by
    which intracompany point-to-point data transmission is
    accomplished, but urges that data transmission services was
    otherwise intended to be limited to that specific service.
    II. ANALYSIS
    Before turning to the specific question before us, we
    begin with an overview of central assessment and how it
    differs from local assessment of property. That background
    provides helpful context for the statutory interpretation
    issue presented.
    A.  Central Assessment Generally
    What we now term “central assessment” had its ori-
    gins in unit valuation, an assessment method that emerged
    in the latter half of the 19th century. Unit valuation, or
    the so-called “unit rule,” was devised to address the diffi-
    cult task of valuing a business as a going concern when the
    property of the business is located in more than one taxing
    district. James C. Bonbright, 2 The Valuation of Property
    633 (1937).2 Courts generally disfavored such valuations,
    2
    Railroad property is a prime example of the kind of property suited to
    assessment using the unit rule. Originally, local assessors used unit valuation
    290	                                    Comcast Corp. v. Dept. of Rev.
    however, because of inaccuracies in the assessment method
    and inequities in how it was administered at the local level.
    See, e.g., People ex rel. Delaware, Lackawanna & W. R.R. Co.
    v. Clapp, 152 NY 490, 495-96, 
    46 NE 842
     (1897) (unit valu-
    ation “is misleading and impossible of application with any
    approach to justice or accuracy”).
    Assessment by a single state assessment body,
    so-called “central assessment,” developed to remedy the
    perceived problems with unit valuations performed by local
    assessors, particularly in the context of railroad assessments.
    Bonbright, 2 The Valuation of Property at 637. Foremost
    among the solutions presented by central assessment was
    that it withdrew “the difficult task of assessing fractional
    parts of a railroad and its property from the hands of local
    assessors” likely to favor their own district in their assess-
    ment. Union Pacific Railway Co. v. Cheyenne, 
    113 US 516
    ,
    522, 
    5 S Ct 601
    , 
    28 L Ed 1098
     (1885). Central assessment
    also allowed assessors to capture additional value inherent
    in certain property. In particular, central assessment made
    possible “assessments which would reach those large intan-
    gible values, called franchise value or good will, which could
    not be effectively taxed by local assessors.” Bonbright, 2
    The Valuation of Property at 637 (internal quotation marks
    omitted). As the United States Supreme Court explained in
    Cleveland Railway Co. v. Backus, 
    154 US 439
    , 444, 
    14 S Ct 1122
    , 
    38 L Ed 1041
     (1894):
    “The true value of a line of railroad is *  * the aggregate
    *
    of those values plus that arising from a connected opera-
    tion of the whole, and each part of the road contributes not
    merely the value arising from its independent operation,
    but its mileage proportion of that flowing from a continuous
    and connected operation of the whole.”
    Thus, many states set up state boards of assessment for the
    purpose of assessing certain property as a single unit on a
    statewide or “central” basis.
    to value railroad property—usually a segment of track—in their taxing district
    as a portion of the property of a particular railroad’s entire business. Bonbright,
    2 The Valuation of Property at 635. The value of the railroad property located
    in a county was calculated in proportion to the value of the all of the railroad’s
    property as a going concern. Telegraph, telephone, pipeline, and other companies
    with property that crossed into more than one taxing district also were commonly
    assessed using the unit rule.

    Oregon was among those many states. In 1909,
    the Oregon Legislature formed the Board of State Tax
    Commissioners (the tax board) for the purpose of taxing
    certain property as a single unit on a statewide basis. In
    particular, the legislature enacted Lord’s Oregon Laws, title
    XXVIII, ch VI, § 3614 to 3660 (Oregon Laws 1909, chap-
    ter 218), the predecessor statutes to the central assessment
    statutes now set out at ORS 308.505 to ORS 308.665. The
    duty of the tax board, among other things, was:
    “To make an annual assessment *  * of the property hav-
    *
    ing a situs in this state * * * of all railroad companies, sleep-
    ing car companies, union station and depot companies,
    electric and street railway companies, express companies,
    telegraph companies, telephone companies, refrigerator
    car companies, oil and tank line companies, and of such
    heat, light, power, water, gas, and electric companies as
    may be doing business as one system, partly within this
    state and partly without, or so doing business in more than
    one county of the state.”
    Lord’s Oregon Laws, title XXVIII, ch VI, § 3617(15) (1909)
    (predecessor to ORS 308.515). The legislature directed the
    tax board to value the property subject to its assessment
    authority according to the unit rule. Lord’s Oregon Laws,
    title XXVIII, ch VI, § 3623 (1909) (board “may value the
    entire property, both within and without the [S]tate of
    Oregon, as a unit” to ascertain the “actual cash value of the
    property assessable by it”).
    Oregon’s original central assessment scheme was
    consistent with the development of unit valuation and cen-
    tral assessment statutes nationally. The legislature sub-
    jected two broad categories of property to central assess-
    ment. The first encompassed property operated as a network
    over a geographically large area, such as the property of
    railroad, telegraph, telephone, and pipeline companies. It
    also included the property of public utility-type companies,
    such as heat, light, power, and water companies, but only
    if the utilities did business “as one system” across state or
    county lines. Id. § 3617(15). The second category encom-
    passed non-networked property that was associated with
    the networked property in the first category. Thus, sleeping
    292	                                    Comcast Corp. v. Dept. of Rev.
    car, refrigerator car, union station, depot, and express3 com-
    panies were also subject to central assessment. Id.
    Over the next several decades, the statute remained
    focused on the two categories of property originally subject
    to central assessment, despite additions and deletions of var-
    ious types of companies. See, e.g., Oregon Code, title LXIX,
    ch 4, § 69-404(15) (1930) (including “private car companies”
    and “tank line companies,” and omitting “oil and tank line
    companies”), OCLA § 110-505(14) (1940) (including “pipe
    line companies, toll bridge companies, heating companies,”
    “people’s utility districts and aircraft companies engaged in
    air transport of passengers, freight, express or mail”). In
    1951, the legislature restructured ORS 308.515 into its cur-
    rent form. For the most part, rather than list specific com-
    panies that were subject to central assessment, the legis-
    lature instead identified the companies in a more general
    way by describing the nature of service that they provided
    or the business that they were in—that is, all companies
    “engaged in performing or maintaining any of the [listed]
    businesses or services.” Or Laws 1951, ch 586, § 2. Thus,
    the statute listed “railroad transportation,” “telegraph com-
    munication,” and “telephone communication” instead of rail-
    road, telegraph, and telephone companies specifically. Id.4
    The 1951 restructuring generally remains in place today,
    although certain specified commodities are now also sub-
    ject to central assessment, and the listed commodities, busi-
    3
    An “express company” was the forerunner of companies today like UPS
    and FedEx. An express company, however, did not own the “means of convey-
    ance” — it simply carried “packages on passenger and express trains, steamboats
    and stages in the care and custody of its employés [sic] who accompany the pack-
    ages * * * and simply pays to the railroad companies and the owners of the steam-
    boats and stage coaches for the passage of messengers and their accompanying
    packages.” Adams Express Company v. Ohio, 
    165 US 194
    , 202, 
    17 S Ct 305
    , 
    41 L Ed 683
     (1897).
    4
    The purpose of the statute and the nature of the property subject to cen-
    tral assessment did not change with the 1951 amendments. Property operated
    as a network over a geographically large area, such as property involved in rail-
    road transportation, electric rail and trackless trolley transportation, telegraph
    communication, telephone communication, along with heating, water, gas, and
    electric companies, remained subject to central assessment. See Or Laws 1951,
    ch 586, § 2 (listing businesses and services). And non-networked property asso-
    ciated with the networked property, such as railroad switching and terminal,
    sleeping car, refrigerator car, private car, and tank car businesses or services,
    along with certain kinds of air and water transportation, also remained subject
    to central assessment after the 1951 restructuring. Id.

    nesses, and services subject to central assessment are set
    out in paragraphs of a single section of the statute providing
    for central assessment of property. ORS 308.515(1).
    B.  Central Assessment of “Communication” and “Data
    Transmission Services”
    That overview of central assessment generally and
    the evolution of Oregon’s specific central assessment scheme
    brings us to the statutes as they exist today. The statutes
    that provide for the assessment and taxation of property in
    Oregon are consolidated in ORS chapter 308. As a general
    matter, Oregon property is assessed in one of two ways—
    it is either centrally assessed by the department or locally
    assessed by a county assessor. ORS 308.517(5) (all property
    not assessed by the department assessed by county assessor
    of county in which property situated). As noted, the current
    central assessment scheme is codified under ORS 308.505 to
    ORS 308.665.5
    The particular dispute that we must resolve in
    this case involves ORS 308.505 and ORS 308.515. ORS
    308.515(1) provides for the central assessment of certain
    businesses, services, and commodities:
    “The Department of Revenue shall make an annual
    assessment of any property that has a situs in this state
    and *  * is used or held for future use by any company in
    *
    performing or maintaining any of the following businesses
    or services or in selling any of [certain] commodities * * *[.]”
    The statute goes on to list the particular services, businesses,
    and commodities that are subject to central assessment.
    5
    The parties cite the 2007 version of the statute, then-numbered ORS
    308.505(2). In 2009, the legislature renumbered parts of the statute. As a result,
    the definition of communication is now codified as ORS 308.505(3). The legisla-
    ture also amended the definition of “communication” in ORS 308.505(3) to remove
    the reference to “telegraph communication,” see Or Laws 2009, ch 128, § 3, which
    by then effectively had ceased to exist. Those changes were part of a more exten-
    sive bill that updated archaic language, reordered definitions, and conformed
    wording throughout the central assessment statutes. The legislative history for
    the bill makes clear that the department, as the sponsor of the amendments, was
    not proposing any substantive change to the statutes. Or Laws 2009, ch 128,
    § 1 (purpose of the 2009 amendments was “to modernize and clarify the central
    assessment statutory law, while continuing the central assessment system as it
    currently operates”; amendments “do not constitute a change in the policies of
    the State of Oregon”). Thus, the deletion of “telegraph communication” has no
    bearing on this case. We analyze and refer to the 2007 version of the statute,
    then-numbered ORS 308.505(2).
    294	                                    Comcast Corp. v. Dept. of Rev.
    It bears emphasizing, however, that only the property used
    in the business, service, or commodity is assessed (and thus
    taxed). The value of the business, service, or commodity
    itself is not subject to central assessment.
    Until 1973, ORS 308.515(1) specifically included
    “telegraph communication” and “telephone communication”
    together with other centrally assessed businesses and ser-
    vices such as railroad transportation, air transportation,
    heating, gas, and electricity. ORS 308.515(1)(a) (1971). In
    1973, however, the legislature replaced the references to tele-
    graph and telephone communication with the more general
    term “communication.” Or Laws 1973, ch 402, § 8 (Senate
    Bill 81). Simultaneously, the legislature further described
    what “communication” includes in a way that ensured that
    telegraph and telephone communication services would con-
    tinue to be centrally assessed, but so would additional com-
    munication services as well. In particular, the legislature
    amended ORS 308.505 to specify that the term “communi-
    cation,” as used in the statutes governing central assess-
    ment, “includes telephone communication, telegraph com-
    munication, and data transmission services by whatever
    means provided.” Or Laws 1973, ch 102, § 1 (codified as ORS
    308.505(2)).6
    As earlier described, the dispute in this case centers
    on the 1973 addition to the statute that made “data trans-
    mission services by whatever means provided” a commu-
    nication service that is subject to central assessment. The
    dispute arises now, some 40 years after the 1973 amend-
    ments, because the department, until recent tax years, did
    6
    The parties debate at some length whether the term “includes” as used
    in the statute is one of inclusion or limitation. The department argues that
    the use of the term “includes” indicates that the statute was intended to be a
    nonexclusive list of representative “communication” services, and that services
    other than those listed (that is, other than telephone communication, telegraph
    communication, and data transmission services) are also centrally assessable if
    they qualify more generally as a communication. Comcast argues in response
    that “includes” was intended to limit the term “communication” to the services
    that are listed. Consequently, in Comcast’s view, if neither its internet access
    nor its cable television service qualify as “data transmission services,” which is
    the only listed service that they arguably would fit, those services are not cen-
    trally assessable. Because we later conclude that both Comcast’s cable television
    and internet access services are “data transmission services,” we do not have to
    decide whether “communication” services are limited to the ones listed in ORS
    308.505(2) or include other services as well.

    356 Or 282
     (2014)	295
    not take the position that Comcast’s cable television and
    internet access services are data transmission services
    within the meaning of ORS 308.505(2). As we will describe
    in greater detail later, cable television service existed at the
    time of the 1973 amendments, but the technology involved
    in delivering that service has undergone significant change
    since then. Internet access service, on the other hand, did
    not exist at all in 1973. How the policy that the legislature
    adopted in 1973 applies to the cable television and inter-
    net access services supplied by Comcast today lies at the
    heart of the disagreement between the parties. In Comcast’s
    view, because “data transmission services” in 1973 were not
    used to provide either cable television or internet access ser-
    vice, to conclude now that those services are data transmis-
    sion services would distort the legislature’s intent. In the
    department’s view, the legislature did not intend to limit
    “data transmission services” to the particular applications
    or uses that existed when the legislature amended the stat-
    ute in 1973; rather, such services were intended to encom-
    pass any new or evolving business that, from a technological
    standpoint, serves its customers through the service of data
    transmission.
    To resolve the parties’ disagreement, we use our
    familiar methodology for interpreting statutes. In particu-
    lar, we first explore the text and context, and we then turn
    to the legislative history of the pertinent statutes. State v.
    Gaines, 
    346 Or 160
    , 171-72, 206 P3d 1042 (2009). As we will
    explain, in this particular instance, we conclude that “data
    transmission services” is a technical term, which requires
    us to explore the meaning and usage of the term in the spe-
    cialized field from which it was borrowed.
    1.  Plain Text and Context
    Our goal in interpreting a statute is to determine
    what meaning the legislature intended in drafting the stat-
    ute. PGE v. Bureau of Labor and Industries, 
    317 Or 606
    , 610,
    859 P2d 1143 (1993). When the legislature provides a defi-
    nition of a statutory term, we of course use that definition.
    Otherwise, we ordinarily look to the plain meaning of a stat-
    ute’s text as a key first step in determining what particular
    terms mean. 
    Id. at 611
     (first step in statutory analysis is
    296	                                    Comcast Corp. v. Dept. of Rev.
    to consider “plain, natural, and ordinary meaning” of text).
    And, as stilted as the approach may sometimes seem, we
    frequently consult dictionary definitions of the terms, on the
    assumption that, if the legislature did not give the term a
    specialized definition, the dictionary definition reflects the
    meaning that the legislature would naturally have intended.
    See State v. Murray, 
    340 Or 599
    , 604, 136 P3d 10 (2006) (so
    explaining).7
    An exception to that approach arises when the leg-
    islature uses technical terminology—so-called “terms of
    art”—drawn from a specialized trade or field. In that cir-
    cumstance, we look to the meaning and usage of those terms
    in the discipline from which the legislature borrowed them.
    So, for example, when a term is a legal one, we look to its
    “established legal meaning” as revealed by, for starters at
    least, legal dictionaries. See, e.g., Dept. of Rev. v. Croslin, 
    345 Or 620
    , 628, 201 P3d 900 (2009) (resorting to Black’s Law
    Dictionary for definition of “damages”). We potentially also
    consider the overall statutory scheme in which a legal term
    appears, as well as the meaning that the term has for regula-
    tors who oversee the field. See, e.g., Dept. of Transportation v.
    Stallcup, 
    341 Or 93
    , 99-102, 138 P3d 9 (2006) (“appraisal” in
    condemnation statute is a legal term; legal dictionary defini-
    tion considered together with overall statutory scheme and
    interpretation by board that regulates and certifies apprais-
    ers). Likewise, when the legislature uses terms drawn from
    disciplines such as psychiatry, medicine, or other special-
    ized areas, the court determines the meaning of those terms
    based on how they are used and understood in the special-
    ized field, trade, or profession, and using sources that best
    accord with the legislature’s intent. See, e.g., Tharp v. PSRB,
    
    338 Or 413
    , 423, 110 P3d 103 (2005) (in statute providing for
    guilty except for insanity defense, “ ‘mental disease or defect’
    and ‘personality disorder,’ * * * are terms of art that are used
    7
    In particular, this court most often looks to the definitions provided in
    Webster’s Third New Int’l Dictionary (unabridged ed 2002). See Kohring v.
    Ballard, 
    355 Or 297
    , 304 n 2, 325 P3d 717 (2014) (noting frequency of citation and
    explaining likely reason for resorting to Webster’s Third over other dictionaries).
    In consulting dictionaries, however, it is important to use sources contemporane-
    ous with the enactment of the statute. See, e.g., State v. Perry, 
    336 Or 49
    , 53, 77
    P3d 313 (2003) (“In interpreting the words of a statute enacted many years ago,
    we may seek guidance from dictionaries that were in use at the time.”).

    in the context of professional disciplines such as psychiatry
    and psychology”); Mueller v. PSRB, 
    325 Or 332
    , 339, 937 P2d
    1028 (1997) (in context of determining Psychiatric Security
    Review Board’s jurisdiction over petitioner, phrase “person-
    ality disorder” is “term of art as to which the DSM-III was
    the definitive source”).
    Here, neither party approaches the phrase “data
    transmission services” as one that is best interpreted by
    reference to a common and natural meaning.8 Rather, both
    parties more or less assume that the term is a technical
    term of art. They then to attempt to determine that techni-
    cal meaning, arriving at markedly different conclusions in
    the process.
    At the outset, we agree that “data transmission
    services” is a technical phrase that we should interpret as
    such. The words in combination are the first clue that points
    to that conclusion. Although the phrase consists of common
    individual words, collectively they have no familiar or com-
    mon meaning. For instance, the definition of “datum,” the
    singular of the otherwise undefined “data,” is not helpful
    even as a starting point:
    “[S]omething that is given either from being experientially
    encountered or from being admitted or assumed for specific
    purposes : a fact or principle granted or presented : some-
    thing upon which an inference or an argument is based or
    from which an intellectual system of any sort is constructed
    * * * : material serving as a basis for discussion, inference,
    or determination of policy * * * : detailed information of any
    kind[.]”
    Webster’s Third New Int’l Dictionary 577 (1971). When com-
    bined with the other terms in the phrase—”transmission”
    and “services”—the phrase does not lend itself to any com-
    mon or ordinary lay meaning.9 As is often true of other
    8
    In its brief, the department makes some effort to interpret the phrase based
    on its common meaning, but then focuses on the technical meaning of “data
    transmission services.” As we will explain, the effort to piece together a collective
    lay meaning from the individual words of the phrase is not helpful, and just as
    the department turns quickly to technical sources, so do we.
    9
    See also Webster’s at 2075 (defining “service” as, among other things, “use-
    ful labor that does not produce a tangible commodity,” “the provision, organiza-
    tion, or apparatus for conducting a public utility or meeting a general demand,”
    and “offering a product useful only in making another product or in performing
    298	                                     Comcast Corp. v. Dept. of Rev.
    technical terminology, it would be “futile” to try to cobble
    together definitions of the individual words to make collec-
    tive sense of the phrase as a whole. See, e.g., Tharp, 
    338 Or at 423
     (observing futility of giving terms “mental disease or
    defect” an ordinary or common meaning).
    The context in which the phrase appears likewise
    points to its technical nature. And, more helpfully, context
    points to the technical field from which its meaning should
    be drawn. As noted, before the 1973 amendments added data
    transmission services to the central assessment scheme,
    ORS 308.515 specifically designated “telegraph communi-
    cation” and “telephone communication” as services or busi-
    nesses subject to central assessment. ORS 308.515(1)(a)
    (1971). Senate Bill 81 (SB 81) deleted the specific references
    to telephone and telegraph communication and replaced
    them with the much more general reference to the business
    or service of “communication.” ORS 308.515(1).
    Had the legislature left the statute in that form,
    the term “communication” might have been exceptionally
    broad, encompassing any service, business, or commodity
    that entailed any verbal, written, or electronic exchange
    of thoughts, ideas, or information.10 Simultaneously, how-
    ever, the legislature amended ORS 308.505 to provide that
    “communication” includes telephone and telegraph com-
    munication, thus tying the term to the traditionally cen-
    trally assessed field of telecommunications.11 Or Laws 1973,
    associated tasks or services”); id. at 2429 (defining “transmit” as, among other
    things, “to cause to go or be conveyed to another person or place,” “to pass on or
    spread about,” and “to cause (as light or force) to pass or be conveyed through
    space or a medium”).
    10
    “Communication” as a lay term is defined in pertinent part as:
    “1 : the act or action of imparting or transmitting * * * 2 a : facts or informa-
    tion communicated b : a letter, note, or other instance of written information
    * * * 3 a obs : conversation, talk * * * b communications pl : means of com-
    municating: (1) : a system (as of telephones or telegraphs) for communicating
    information and orders (as in a naval service) *  * (3) : the function in an
    *
    industrial organization that transmits ideas, policies, and orders *  * 6 a :
    *
    interchange of thoughts or opinions : a process by which meanings are
    exchanged between individuals through a common system of symbols (as
    language, signs, or gestures).”
    Webster’s at 460.
    11
    We use the term “telecommunications” in the same way that it was used
    by David Olson, a Professor of Telecommunications Law, who was asked to define
    Cite as 
    356 Or 282
     (2014)	299
    ch 102, § 1. And, also simultaneously, the legislature added
    “data transmission services” as an additional business or
    service that qualifies as “communication.” Id. ch 402, § 8.
    The central assessment scheme is one that, as we have
    described, generally encompasses regulated and highly spe-
    cialized businesses, industries, and services that depend on
    networked lines of transportation or transmission that cross
    geographical boundaries. The fact that “data transmission
    services” is part of that scheme contextually confirms that
    the phrase “data transmission services” is a technical one.
    As important, the fact that the service is listed under “com-
    munication” along with telephone and telegraph communi-
    cation services strongly suggests that the phrase was drawn
    from the telecommunications field.
    2.          Technical Meaning
    Although the parties seem to agree that “data
    transmission services” was intended by the legislature to be
    a technical term, their agreement ends there. They disagree
    on what sources we may consider to determine its meaning,
    as well as on the ultimate meaning of the phrase—that is,
    they disagree on the nature of the businesses and services
    that the legislature understood to fall within the phrase.
    The department begins by exploring technical
    sources for a definition of the term. One contemporaneous
    source that the department cites is Harley Carter, Dictionary
    of Electronics 354 (2d ed 1972):
    “Data Transmission. Broadly speaking, any process of
    transmitting information, but the term now has a spe-
    cialized meaning, namely the transmission of information
    via telecommunication circuits in some code, such as the
    Binary Scale, for Data Storage and processing.”
    The department’s other sources for relevant technical defini-
    tions are generally to the same effect.12
    it when he testified before the Tax Court. He explained that the term “commu-
    nication” within the field means “voice, video and data” and that “telecommuni-
    cation” simply means “voice, video, and data sent over a distance.” Because of its
    prevalence in everyday life, “telecommunication,” although a technical term, has
    acquired a common meaning that is effectively the same: “1 : communication at a
    distance (as by cable, radio, telegraph, telephone, or television) 2 : the science that
    deals with telecommunication  usu. used in pl.” Webster’s Third at 2349.
    12
    See, e.g., IEEE Standard Dictionary of Electrical and Electronics Terms
    161 (2d ed 1977) (defining “data transmission” as “[t]he movement of encoded
    300	                                  Comcast Corp. v. Dept. of Rev.
    Comcast, for its part, offers no technical definitions
    in support of its position or that otherwise contradict those
    that the department provides. Rather, Comcast responds to
    the department’s citations by asserting, in effect, that we
    should not look to technical dictionaries because they do
    not have the same “notoriety” as do dictionaries of common
    usage, such as Webster’s Third. Moreover, Comcast urges,
    the department has not demonstrated that the legislature
    “consulted or referenced any technical dictionaries” when it
    added “data transmission services” to the statute in 1973. In
    Comcast’s view, apparently, technical sources that establish
    the settled meaning of technical or other terms of art are
    irrelevant unless the legislature was aware of the technical
    meanings of the terms that it adopts.
    We know of no principle that prevents the legislative
    branch of government from adopting the technical meaning
    of terms as they are used and understood in a specialized
    trade or field without the legislature first being fluent in
    that meaning. Certainly, our own cases have not burdened
    the legislative process with such a requirement. We have,
    instead, been willing to consult technical sources for the
    meaning of technical terms, without first asking whether
    the legislature did so. See, e.g., Croslin, 
    345 Or at 628
     (using
    legal dictionary to define legal term); Mueller, 
    325 Or at 339
    (using psychiatric diagnostic manual to construe meaning
    of “personality disorder”). Indeed, we have consulted such
    sources in circumstances where the legislative history
    revealed that the meaning to be given to a technical term
    was a source of debate during the legislative process, with
    the result that “the legislature had an ‘idea’ of the meaning
    of the term,” but left the task of defining it more precisely to
    “the common law, the [administrative tribunal that hears
    disputes in the area], and the appellate courts.” Hopkins v.
    SAIF, 
    349 Or 348
    , 360, 245 P3d 90 (2010) (interpreting term
    “arthritis” for purposes of workers compensation statute).
    Our approach to the interpretation of technical terms is a
    time-honored one. See William Blackstone, 1 Commentaries
    information by means of communication techniques”) and Elsevier’s Dictionary of
    Computers, Automatic Control and Data Processing 89 (2d ed 1971) (“data trans-
    mission” defined as “the transmission between remote points of data in coded
    form by means of signals”).

    on the Laws of England 59 (1765). (“[In interpreting legisla-
    tion,] terms of art, or technical terms, must be taken accord-
    ing to the acceptation of the learned in each art, trade, and
    science.”).
    That is not to say that, in interpreting “data trans-
    mission services” in this case, we must automatically adopt
    the technical definitions provided by sources such as those
    that the department cites.13 The interpretation to be given
    to the phrase “data transmission services” still depends on
    what meaning the legislature intended. If the legislature’s
    intent was to borrow from a technical field, then we look
    to that technical field, consulting technical sources for the
    range of meanings a term may entail and selecting from
    those meanings in a way that is consistent with the “idea”
    of the meaning that the legislature had in mind. See 
    id. at 361-64
     (concluding that legislature would have intended
    term “arthritis” to encompass core aspects of condition, as
    revealed by medical sources; rejecting argument that term
    should be limited to a particular form of arthritis—osteoar-
    thritis—when legislative history revealed no intent for more
    limited form). It is helpful, therefore, to examine legislative
    history to see whether it confirms that the phrase “data
    transmission services” was drawn from the telecommunica-
    tions field and, if so, what the history conveys about the leg-
    islature’s understanding of the phrase’s technical meaning.
    3.           Legislative History
    The parties agree that the impetus for the 1973
    amendments that added “data transmission services” to
    the central assessment scheme arose when the Federal
    Communications Commission (FCC) began licensing com-
    panies as specialized common carriers to compete with
    13
    In Davidson v. Oregon Government Ethics Comm., 
    300 Or 415
    , 420, 712
    P2d 87 (1985), this court stated that we do not give effect to the intent of the
    legislature “by consulting dictionary definitions of words, unless there is reason
    to believe that the legislature consulted the same dictionary” and “no single dic-
    tionary is authoritative.” We further observed, however, that dictionary mean-
    ings are appropriate to consult to the extent they are “compatible with legislative
    policy.” 
    Id. at 421
    . Our approach here is the same. Unless the legislature is shown
    to have chosen its words in reliance on a particular dictionary definition of them,
    no particular dictionary is “authoritative” or otherwise controlling. But that does
    not mean that this court should not consult dictionary definitions of both plain
    and technical terms to assist in interpreting a statute in a way that is consistent
    with legislative intent.

    ically distant locations via point-to-point microwave trans-
    missions. Washington Utilities & Transp. Com’n v. F.C.C.,
    513 F2d 1142, 1155 (9th Cir 1975). Although the same pri-
    vate line service was available through existing telephone
    transmission lines, microwave technology offered distinct
    advantages. Georgia Persons, The Making of Energy and
    Telecommunications Policy 88 (1995). In particular, the pro-
    posed microwave network would be low cost, would allow for
    rapid connection and high availability of lines, would provide
    a wider selection of transmission speeds, and would have
    lower transmission error rates. See Specialized Common
    Carrier Decision, 29 FCC 2d at 953 (discussing advantages
    cited by proposed carriers).
    As a result of FCC approval to construct a micro-
    wave communication network along the Pacific Coast (from
    Seattle to San Diego), the department proposed the amend-
    ments to the central assessment statutes set out in SB 81.
    The purpose of SB 81 was to ensure that the planned micro-
    wave communication infrastructure would be subject to cen-
    tral assessment along with the existing telephone and tele-
    graph infrastructures. See Tape Recording, House Revenue
    Committee, SB 81, Apr 20, 1973, Tape 35, Side 2 (“[I]t’s
    currently under construction across the state of Oregon
    *  * a microwave communications network that will link
    *
    Seattle, San Francisco, Los Angeles, and so on. *  * We’d
    *
    like to clearly include the assessment of [the planned com-
    munication network] within the Department of Revenue’s
    jurisdiction.”) (statement of Victor Bredehoeft, Department
    of Revenue).
    Discussions during committee hearings and floor
    debates bear out our conclusion that the legislature under-
    stood “data transmission services” as a technical phrase
    drawn from the telecommunications field. For instance, in
    a Senate Revenue Committee hearing, the department rep-
    resentative explained that SB 81 would “clarify” the central
    Cite as 
    356 Or 282
     (2014)	303
    assessment statutes by ensuring that “newly emerging
    data transmission services” would be, along with telephone
    and telegraph services, communications services subject
    to central assessment. Tape Recording, Senate Revenue
    Committee, SB 81, Feb 9, 1973, Tape 10, Side 2 (statement
    of Victor Bredehoeft, Department of Revenue).
    The legislative history also reveals that the new
    communications service of data transmission was unfamil-
    iar to legislators. One senator asked, “What is data trans-
    mission? Is this the phone-to-phone * * * kind of thing?” 
    Id.
    (statement of Senator Atiyeh). The department representa-
    tive answered in the affirmative, explaining it was “the kind
    of thing” that involves “the transmission over telephone
    facilities or microwave [facilities] of data between comput-
    ers primarily, or data from a computer terminal into a com-
    puter, or other nonverbal kind of data communication.” 
    Id.
    (statement of Victor Bredehoeft, Department of Revenue).
    When SB 81 was later introduced for a vote on the Senate
    floor, the comments of the senator who introduced it, too,
    reflect that the phrase “data transmission services” was a
    technical one that was meaningful in the telecommunica-
    tions field, even if legislators had only a limited understand-
    ing of that meaning:
    “SB 81 ha[s] to do with [the] definitions of communications.
    The present language could very easily ignore *  * a new
    *
    type of communication which is known as—now I’m try-
    ing to think of the word—it had to do with communications
    between computers or data processing or that type of commu-
    nication. * * * [I]t is questioned whether [telegraph and tele-
    phone communication] really encompass a computer-type of
    transmission of information.”
    Tape Recording, Senate Floor Debate, SB 81, Feb 15, 1973,
    Reel 3, Side 2 (statement of Senator Hoyt) (emphasis added).
    A House member’s description of SB 81 when it later came to
    a vote on the House floor was similar:
    “[T]he Department of Revenue can assess statewide cer-
    tain items including communication and this included
    telephones and telegraph communication. There is a new
    one that has come up and that is data processing trans-
    mission by microwave and this simply adds this type of
    304	                                    Comcast Corp. v. Dept. of Rev.
    transmission to the present law. And it is a technical addi-
    tion mainly.”
    Tape Recording, House Floor Debate, SB 81, May 8, 1973,
    Reel 16, Track 1 (statement of Representative Cherry).
    The department, relying principally on those por-
    tions of the legislative history, urges that “data transmission
    services” was added to the description of centrally assessed
    “communication” services to capture emerging technology by
    which encoded data could more efficiently be sent between
    geographically remote computers or similar devices capable
    of sending and receiving that data. Comcast, however, urges
    that the legislature’s purpose was much narrower and that
    the meaning the legislature ascribed to “data transmission
    services” was narrow as well.
    In particular, Comcast points to the portions of the
    legislative history referring to the planned construction of
    the microwave communication network along the west coast:
    “This bill is for the purpose of clarifying the language of the
    utility assessment statutes to make it clear that a new type
    of industry will come under our assessment jurisdiction,
    that is point-to-point microwave communications service.”
    Tape Recording, House Revenue Committee, SB 81, Apr 20,
    1973, Tape 35 (statement of Victor Bredehoeft, Department
    of Revenue). Comcast also points to an exchange during
    the department’s testimony before the Senate Revenue
    Committee. There, a senator asked: “All I know about it
    is what I’ve seen advertised, *  * but you’re talking about
    *
    my company communicating with a branch of my company
    somewhere else[,]” to which the department representative
    responded, “Exactly.”14 Tape Recording, Senate Revenue
    Committee, SB 81, Feb 9, 1973, Tape 10, Side 2 (statements
    of Victor Bredehoeft, Department of Revenue, and unnamed
    senator). According to Comcast, those portions of the leg-
    islative history support its position that the legislature
    intended the phrase “data transmission services” to mean
    14
    In his explanation, Bredehoeft went on to explain that if a company estab-
    lished such a service only for its own use, it would not qualify under the statute
    because a company must offer the service “for hire” — that is, a company “pro-
    viding these communication services must offer them to the general public for a
    fee.” Tape Recording, House Revenue Committee, SB 81, Apr 20, 1973, Tape 35
    (statement of Victor Bredehoeft, Department of Revenue).

    only the intracompany transmission of business data via the
    private lines that would be offered over the newly licensed
    microwave communications infrastructure.
    The legislative history as a whole, however, does
    not show that the legislature had the narrow intent that
    Comcast ascribes to it. To be sure, the private line business
    data transmission service that Comcast describes was the
    service that MCI offered in its first application to the FCC in
    1963 to operate as a common carrier in the data communica-
    tion market. See Stuart L. Mathison and Philip M. Walker,
    Regulatory Policy and Future Data Transmission Services in
    Computer Communication Networks, 327 (N. Abramson and
    F.F. Kuo, eds. 1973) (“The MCI carriers plan to interconnect
    their systems and cooperate with each other to provide a
    nationwide private-line communications network.”). And the
    growing demand for private line business data transmission
    services appears to be what drove many other companies
    to quickly follow MCI’s lead and apply for FCC permits to
    construct and operate microwave communication networks.

    , Table 9.5 (table listing microwave network
    applications).
    But Comcast does not confront the portions of the
    legislative history that affirmatively show that the legis-
    lature understood “data transmission services” to be more
    encompassing terminology. In proposing the new language
    as part of SB 81, the department’s representative explained
    to the Senate Revenue Committee that it was designed to
    eliminate confusion that had existed in the past and “may
    exist in the future” in connection with assessment of “certain
    types of communications services.” Tape Recording, Senate
    Revenue Committee, SB 81, Feb 9, 1973, Tape 10, Side 2
    (statement of Victor Bredehoeft, Department of Revenue).
    The department’s representative further explained that SB
    81 eliminated the “discriminatory” references to telephone
    and telegraph communication from current law, and instead
    was directed to “communication” services generally, which
    included telephone and telegraph communication, and also
    “data transmission services by whatever means provided.”
    
    Id.
     The plain import of that testimony was that data trans-
    mission services were not industry-specific—they could be
    provided by telephone, telegraph, and other means. What
    306	                                    Comcast Corp. v. Dept. of Rev.
    was important was the nature of the service itself. The legis-
    lature understood and endorsed the department’s testimony
    describing “data transmission services” in expansive terms
    as the transmission “of data between computers primarily,
    or data from a computer terminal into a computer, or other
    nonverbal kind of data communication.” 
    Id.
    In short, we agree with Comcast that the legislature
    amended the central assessment statutes in 1973 because
    of a particular precipitating problem—viz., the FCC was
    licensing microwave companies to provide private line busi-
    ness data transmission services in competition with tele-
    phone companies. But we agree with the department that
    the legislature did not limit the amendment to that narrow
    problem. That is, it did not amend the statute by specifi-
    cally adding microwave private line data transmission ser-
    vices to the other businesses and services already listed in
    the statute.15 Instead, the legislature opted to expansively
    reach all data transmission services, without regard to the
    use to which the data is put (for example, business rather
    than entertainment or educational uses). The legislature
    frequently makes policy choices of that kind:
    “Statutes ordinarily are drafted in order to address some
    known or identifiable problem, but the chosen solution may
    not always be narrowly confined to the precise problem.
    The legislature may and often does choose broader lan-
    guage that applies to a wider range of circumstances than
    the precise problem that triggered legislative attention.
    For instance, lawmakers may believe that defining a nar-
    rower class for coverage under a statute would cause more
    problems in interpretation and administration and would
    be less efficient than to use broad, residual language that
    avoids such problems. When the express terms of a statute
    indicate such broader coverage, it is not necessary to show
    that this was its conscious purpose. In the absence of an
    affirmative showing that the narrower meaning actually
    was intended by the drafters, we shall take the legislature
    at its word * * *.”
    15
    In the past, the legislature has been specific and narrow when it intended
    to be. For instance, rather than subject “air transportation services” to central
    assessment when it intended only a subset of those services, the legislature spec-
    ified the subset that it intended was “air transportation certificated by the Civil
    Aeronautics Board for scheduled air service.” ORS 308.515(1)(a) (1973).

    , 531,724
    P2d 788 (1986) (footnote omitted). Here, the legislative his-
    tory of the 1973 amendments to the central assessment stat-
    utes confirms that the legislature addressed a particular
    precipitating concern (microwave companies being permitted
    to compete with telephone companies to meet demands for
    private line business data transmission) with a broader pol-
    icy choice (to centrally assess all data transmission services,
    regardless of the means by which they transmit the data).16
    In sum, we conclude based on the text, context, and
    legislative history that the legislature used the phrase “data
    transmission services” with the understanding that it had a
    technical meaning within the telecommunications industry.
    Contrary to Comcast’s position, the phrase was not intended
    to refer only to the particular data transmission service (i.e.,
    private line microwave transmission of intracompany busi-
    ness data) that was creating competition for the first time
    with the telephone industry. Instead, the legislature painted
    with a broader brush and a conscious awareness that “data
    transmission services” in general involved “the transmis-
    sion over telephone facilities or microwave facilities [or other
    means] of data between computers primarily, or data from a
    computer terminal into a computer, or other nonverbal kind
    of data communication.” Tape Recording, Senate Revenue
    Committee, SB 81, Feb 9, 1973, Tape 10, Side 2 (statement
    of Victor Bredehoeft, Department of Revenue).
    4.       Technical Meaning of “Data Transmission
    Services”
    The legislative history thus conveys the general
    sense in which the legislature used and understood the
    16
    Comcast argues that South Beach Marina is “readily distinguishable” from
    this case, because here, unlike in South Beach Marina, legislative history exists
    to inform our understanding of the legislature’s intent. That misses the point.
    In South Beach Marina, we deferred to the broad meaning of the text because
    legislative history did not exist to establish the alternative possibility that the
    legislature intended a narrower meaning. When, as here, legislative history con-
    firms that the legislature intended the broad meaning of the text it used in an
    enactment or amendment, that is an added reason to take the legislature at its
    word. See State v. Walker, 
    356 Or 4
    , 22, __ P3d __ (2014) (“[W]here the legislative
    history demonstrates that the legislature was aware of the expansive nature of
    an enactment’s text, yet chose not to narrow it, we are constrained to interpret
    the statute in a way that is consistent with that text, which is, in the end, the best
    indication of the legislature’s intent.”).
    308	                                    Comcast Corp. v. Dept. of Rev.
    terminology “data transmission services.” It also conveys
    that the legislature adopted it as a technical phrase drawn
    from the telecommunications industry. It is helpful, for that
    reason, to examine the use and meaning of that terminology
    within the specialized field from which the legislature bor-
    rowed it to see if that usage further informs its meaning for
    purposes of ORS 308.505(2).
    “Data transmission” emerged with the advent of the
    computer and, more particularly, with the need to trans-
    mit coded electronic information from one computing device
    to another in a different geographical location. That need
    arose when, beginning in the 1950s, businesses began to
    embrace the computer as a data or information processing
    tool. Andrew Davies, Telecommunications and Politics: The
    Decentralised Alternative 100 (1994). The computer revolu-
    tionized business processes with its ability to efficiently and
    precisely organize, aggregate, analyze, and then communi-
    cate information in electronic form. Id. at 102.17 The capabil-
    ities of a single computer were multiplied when it was con-
    nected to other computers in a way that permitted each to
    easily send and receive information to and from the others.
    Stuart L. Mathison and Philip M. Walker, Computers and
    Telecommunications: Issues in Public Policy vi (1970). That
    development drove the demand to put the telecommunication
    infrastructure to use for something other than voice trans-
    mission: Telephone lines were the means by which comput-
    ing devices could be networked. Davies, Telecommunications
    and Politics: The Decentralised Alternative at 104-05.
    17
    The concept of “information processing” became a formalized part of busi-
    ness activity in the mid- to late-19th century, long before computers existed.
    Davies, Telecommunications and Politics: The Decentralised Alternative at 95.
    For larger companies to make effective and competitive management decisions,
    they had to be able to organize, aggregate, and quickly retrieve records of sales,
    orders, debts, credits, and inventories. Id. As the author of a telecommunications
    regulatory treatise explains, information processing began as a time- and per-
    sonnel-intensive activity that evolved with related advances in technology:
    “[B]y the 1890s, information-processing was entirely paperbased. Large
    armies of clerks and bookkeepers posted figures by hand, and undertook the
    responsibility of screening and retrieving reports. [T]he introduction of elec-
    tromechanical punchcard and tabulating machinery improved the organisa-
    tion [sic] of data into aggregates. Entries were punched on cards which could
    be retrieved by sorting machines and aggregated into totals by tabulating
    machines.”

    “Data transmission service” became the terminol-
    ogy used within the telecommunications field to describe the
    service that carried or transmitted electronic information
    from a computer, data terminal, or other electronic device to
    another computer, data terminal, or other electronic device
    at a geographically distant location. That usage and under-
    standing is reflected in FCC decisions, cases, law review
    articles, and textbooks published in or before 1973, when
    the legislature added “data transmission services” to the
    central assessment statutes.
    For instance, in its application for authorization to
    construct microwave radio facilities to provide specialized
    common carrier services, Data Transmission Corporation
    (Datran) proposed an “all digital communications net work
    specifically engineered for data transmission.” Specialized
    Common Carrier Decision, 29 FCC 2d at 872. In considering
    Datran’s application, the FCC used the term “data transmis-
    sion services” to mean the service of sending information in
    coded electronic form for the purpose of processing that data
    at the other end of the transmission, as this portion of the
    FCC’s decision illustrates:
    “According to Datran, its market studies show that
    major economic sectors, individual consumers, and provid-
    ers of information systems and services in the aggregate
    have a rapidly expanding need for rapid, accurate, low-cost
    data transmission services which is largely unmet by pres-
    ent common carrier offerings. Specifically, Datran claims
    that the costs of existing communications services have not
    declined in proportion to data processing costs; that existing
    analog transmission systems require costly modulator-de-
    modulator equipment to convert digital signals to analog
    and back again; that current switched services often take
    significant time to establish connections, which detracts
    from the productivity of the data terminal and operator;
    that transmission systems originally engineered for voice
    and record transmission do not meet the more demanding
    reliability standards of digital data transmission[.]”
    Id.18
    18
    In the same decision, the FCC went on to describe a similar application by
    MCI. According to MCI, “[t]he computer industry ‘desperately’ needs a commu-
    nications network designed especially for data transmission. MCI would provide
    this network (accepting both analog and digital data signals) and meet many
    310	                                    Comcast Corp. v. Dept. of Rev.
    In a 1966 case reviewing FCC orders resolving
    claims of common carrier rate discrimination, the United
    States Court of Appeals for the District of Columbia Circuit
    noted the changes that had taken place in the telecommuni-
    cations industry in response to the demand for more commu-
    nication services. The following excerpt usefully highlights
    the then-recent communication innovations and illustrates
    again that, well before 1973, “data transmission” was under-
    stood within the telecommunications industry as the service
    of sending information in electronically coded form:
    “Modern government and modern industry have begun
    to require mass communication. Modern science has kept
    pace with these requirements. Thus in a nation-wide busi-
    ness the management frequently does not wish to read over
    a telephone from a central office to one or several branch
    offices the details of a statistical report. Waste of time and
    very great possibility of error in transmission would be
    thus involved. Management wants to reproduce the report
    in San Francisco exactly as it exists in New York. Science
    has supplied the means for doing this. And similarly there
    is equipment and carrying ability for many sorts of data,
    voices, automatic typewriting, photographic reproduc-
    tion, signaling devices, and what is called merely data
    transmission.”
    American Trucking Associations, Inc. v. F.C.C., 377 F2d 121,
    125, (DC Cir 1966) (emphasis added).
    The challenges of setting regulatory policy to meet
    the growing demands for data transmission services spurred
    considerable legal academic discussion. Law review articles
    from the late 1960s and early 1970s generally discussed
    data transmission in the same way that it was discussed in
    the hearings on SB 81—that is, as the transfer and trans-
    mission of coded electronic information between computers
    of the communications needs of the computer industry forecast over the next
    five years *
    * *.” 29 FCC 2d at 875. Similarly, in another decision considering an
    application to establish a nationwide “communications network providing ter-
    minal-computer and computer-computer communications utilizing technology
    known as ‘packet-switching,’  the FCC explained that the applicant sought to
    ”
    serve “data transmission markets.” Packet Communications, Inc., 43 FCC 2d
    922, 922, 923 (1973). The application was supported by Computer Corporation
    of America (CCA), a business that planned to offer “a nation-wide data bank ser-
    vice, which will provide data storage facilities for remote access by computers and
    terminal devices.” Id. at 924.

    or computer-like devices. Because of their forward-thinking
    focus, those articles often described not just then-existing
    demands for data transmission services (such as the micro-
    wave applications for private line intracompany data trans-
    mission), but also anticipated future demands. For instance,
    in 1967, one author forecast:
    “Within the decade, electronic data centers will pro-
    vide computational power to the general public in a way
    somewhat analogous to today’s distribution of electricity.
    Computer systems will blanket the United States, estab-
    lishing an informational grid to permit the mass storage,
    processing, and consumption of a variety of data services:
    computer-aided instruction, medical information, market-
    ing research, stock market information, airline and hotel
    reservations, banking by phone—to mention only a few.”
    Manley R. Irwin, The Computer Utility: Competition or
    Regulation?, 76 Yale L J 1299, 1299 (1967). That same
    author described projections that, within only a few years
    (i.e., by the early to mid-1970s), 50 to 90 percent of all com-
    puters would be “on-line” and “over half of the nation’s com-
    munications will be transmitted as data rather than by
    voice,” which in turn “will bring the data processing and the
    communication industries into unprecedented intimacy.” Id.
    at 1300 (footnote omitted). A 1972 article made what might
    then have been the provocative prediction that computers
    linked to telecommunication lines would soon be in every
    home:
    “[The] combination of computers and communications may
    provide us with the means of establishing a national com-
    puter utility, with computer consoles in every home, on an
    Orwellian model. It is predicted that by the end of this
    decade data communications will exceed voice communica-
    tions and the volume of communications among computers
    will exceed that among humans.”

    tion of Domestic Computer Communications: A Competitive
    Reformation, 22 Buff L Rev 947, 950 (1972) (footnotes
    omitted).
    Textbooks from 1973 and earlier likewise demon-
    strate that “data transmission services” was commonly
    312	                           Comcast Corp. v. Dept. of Rev.
    understood in the telecommunications field to refer gener-
    ally to the transmission of electronic information between
    devices capable of coding and decoding that information
    for any number of purposes. For instance, in a 1970 text-
    book, Stuart L. Mathison and Philip M. Walker explained:
    “Rapid advances in computer technology and in the design
    and programming of large computer systems have increased
    the commercial usefulness of ‘remote access data processing
    systems’—i.e., systems in which data is transmitted by com-
    munications links to and from a computer performing data
    processing functions.” Mathison and Walker, Computers and
    Telecommunications: Issues in Public Policy at 12. Later, in
    1973, those same authors more explicitly referred to “data
    transmission” in the context of exchanging coded electronic
    information in a variety of settings:
    “The importance of the need for suitable and efficient data
    transmission facilities should not be underestimated.
    Computer systems and data networks are proliferating and
    assuming ever-increasing importance in virtually all sec-
    tors of our economy. Vital industries and government orga-
    nizations are becoming increasingly dependent upon data
    transmission facilities—in some cases to the same degree
    that they have come to depend upon nationwide telephone
    service for their day-to-day operations. The operations of
    the stock exchanges, the airlines, and the national air
    defense system, for example, would be crippled were their
    data communication links to fail. The growth of data trans-
    mission both among these users and throughout the U.S.
    economy reflects the fact that data transmission facilities
    will * * * become a part of the nation’s infrastructure.”
    Mathison and Walker, Regulatory Policy and Future
    Data Transmission Services in Computer Communication
    Networks at 296-97.
    Those technical sources uniformly convey that, as
    of 1973, “data transmission services” referred broadly to the
    transmission through telecommunication networks of coded
    information in electronic form. Government, business, and
    others had varied reasons and needs to transmit data over
    a distance, and had varied kinds of information to send
    and receive in data form. As of 1973, the existing demand
    for data transmission services was limited. But there was
    Cite as 
    356 Or 282
     (2014)	313
    widespread recognition that demand would change and
    that data transmission was destined to become the prev-
    alent means of communicating most information across a
    distance.
    The use and meaning of “data transmission ser-
    vices” in the telecommunications industry is thus consistent
    with how the terminology was understood by the legislature
    in 1973. As we have concluded, the legislature understood
    the terminology to be meaningful in the telecommunica-
    tions field and to broadly describe, as the department’s rep-
    resentative put it, “the transmission over telephone facili-
    ties or microwave facilities [or other means] of data between
    computers primarily, or data from a computer terminal into
    a computer, or other nonverbal kind of data communica-
    tion.” Tape Recording, Senate Revenue Committee, SB 81,
    Feb 9, 1973, Tape 10, Side 2 (statement of Victor Bredehoeft,
    Department of Revenue).
    5. whatever means provided”
    “[B]y
    One final aspect of the 1973 amendments deserves
    discussion. In expressly declaring what the service of
    “communication” includes, the legislature specified that it
    “includes telephone communication, telegraph communi-
    cation, and data transmission services by whatever means
    provided.” Or Laws 1973, ch 102, § 1 (codified as ORS
    308.505(2)). Comcast argues, and we agree, that the ital-
    icized text appears to have been added to codify the hold-
    ing in Emerald Loggers Radio Association v. State Tax
    Commission, 
    2 OTR 77
     (1965). The issue in that case was
    whether a private mobile radio communication service was
    subject to central assessment as a “telephone communica-
    tion” service. The service permitted wireless telephone com-
    munication for a distance of about 10 miles and was used by
    34 members of a private association of loggers for two-way
    communication about emergencies, such as fires and inju-
    ries. 
    Id. at 78
    . The Tax Court concluded that, by including
    “telephone communication” services in ORS 308.515 (1965),
    the legislature had used the word “telephone” in its broadest
    sense, which included all businesses involved in “the trans-
    mission of intelligence, messages or sound to a far point”
    regardless of the “means of communication.” 
    Id. at 79

    other words, as long as the service had the essential charac-
    teristics of a telephone service, it qualified as such regard-
    less of the wired, wireless, or other means through which
    the service was provided.
    In the 1973 Senate Revenue Committee hearing on
    SB 81, the department’s representative explained that the
    bill, in addition to adding data transmission services to the
    statute, would also “clarify some of the wording in the exist-
    ing law to eliminate confusion that has existed in the past
    and that may exist in the future[.]” Tape Recording, Senate
    Revenue Committee, SB 81, Feb 9, 1973, Tape 10, Side 2
    (statement of Victor Bredehoeft, Department of Revenue).
    He then described the controversy over centrally assessing
    mobile radio telephone services and explained that litiga-
    tion had been required to sustain the department’s position
    that those services, despite the different means of providing
    them, were telephone communication.19 
    Id.
     The department’s
    solution to avoid similar controversies in the future, while
    also ensuring that the newly emerging specialized “data
    transmission services” would be subject to central assess-
    ment, was to “eliminate the discriminatory phrases—tele-
    graph communication and telephone communication—from
    the present law and simply require it be assessed commu-
    nication services. Then we’ve added the definition for those
    communication services to include telephone communica-
    tion, telegraph communication and data transmission ser-
    vices by whatever means provided.” 
    Id.
    The addition of “by whatever means provided”
    serves in a significant, if subtle, way to confirm our under-
    standing of what the legislature intended “data transmis-
    sion serves” to encompass. The legislature understood “data
    transmission services” to be technology-specific in the sense
    19
    The department representative apparently misspoke in the course of his
    testimony, stating that “[i]t took a [S]upreme [C]ourt case to uphold our position”
    when the only reported case was a decision of the Tax Court. His description
    of the litigation leaves no real doubt that he was referring to the Tax Court’s
    resolution of Emerald Loggers about seven years before: “Some years ago when
    the radio telephone, mobile radio telephone services, were first made available
    by several companies, we interpreted the law at that time as requiring that we
    assess those centrally. It took a supreme court [sic] case to uphold our position
    * * *.” Tape Recording, Senate Revenue Committee, SB 81, Feb 9, 1973, Tape 10,
    Side 2 (statement of Victor Bredehoeft, Department of Revenue).

    that the phrase refers to the transmission of information
    in coded electronic form between computer-like devices. By
    adding the words “by whatever means provided,” the leg-
    islature emphasized that “data transmission services” (as
    well as telephone and telegraph services) were technology-
    neutral in terms of the means or medium of the transmis-
    sion. Thus, the service of data transmission—that is, the ser-
    vice of transmitting information in electronically coded form
    between computers and computer-like devices—remains
    that service regardless of whether the transmission is over
    wire, microwave, radio wave, coaxial cable, fiber optic cable,
    or any other medium that can serve as a means of transmit-
    ting the data between devices.
    6.
    Summary: The Legislature’s Intended Meaning
    We conclude that, in amending the central assess-
    ment statutes in 1973 to include “data transmission ser-
    vices,” the legislature adopted that phrase from the telecom-
    munications field, intending it to have the meaning that it
    has within that field. Drawing from the accepted technical
    meaning and usage of that phrase, we conclude that “data
    transmission services” are services that provide the means
    to send data from one computer or computer-like device to
    another across a transmission network. Data, in turn, is
    information—whether it originated as voice, video, text, or
    anything else—that is sent between computers or computer-
    like devices in coded electronic form. The specific technology
    used to transmit the data—that is, the “means” of transmis-
    sion, whether microwave, wire, coaxial, fiber optic, or some-
    thing else—does not matter. Instead, the defining quality
    of a data transmission service is that it provides the means
    to transmit data over a distance between computers or
    computer-like devices.
    III. APPLICATION
    With that interpretation of “data transmission ser-
    vice” in place, we turn to the particular services that are in
    dispute in this case: internet access and cable television. As
    a factual matter, the Tax Court found that “[t]he cable tele-
    vision business and the internet access business each involve
    the communication of data.” Comcast Corp., 20 OTR at 320.
    316	                                  Comcast Corp. v. Dept. of Rev.
    Later in its analysis, the Tax Court emphasized that “the
    information transmitted through or by way of the services
    offered by Comcast is ‘data’ under any acceptable definition.”
    Id. at 335. Although we agree with the Tax Court that both
    services transmit data, our interpretation of the statutory
    phrase “data transmission services” requires a more precise
    characterization of the transmitted data—that is, the data
    must be in the form of information encoded for transmission
    between computers or computer-like devices.
    Before we examine the services that Comcast
    now provides, it is helpful to briefly sketch the evolution
    of those services. The telecommunications industry—cable
    included—has undergone massive change since 1973. In
    1973, it was technologically possible to use data transmis-
    sion to deliver content of all kinds (e.g., voice, video, and
    text), but the infrastructure and the demand to do so on
    a broad scale did not exist. As we explain below, however,
    that began to change in the 1980s, and the change accel-
    erated during the 1990s. The advent of digital technology
    and high-speed internet resulted in the phenomenon of
    telecommunications “convergence.” With that convergence,
    services—such as voice and video transmission—that were
    once predominantly accomplished using distinctive and dif-
    ferent infrastructures have all technologically migrated
    to data transmission. We therefore begin by describing
    that transformation within the telecommunications indus-
    try, because that background aids in understanding how
    the cable industry generally—and Comcast included—has
    become one engaged in data transmission services, even
    though it was not such a service in 1973.
    A.  The Evolution of Cable Services and the Convergence of
    Cable, Telephone, and Internet Services
    A department witness called to testify at the trial
    before the Tax Court, Professor Patrick Parsons,20 provided
    an overview of the beginnings of cable television and how
    the cable industry has evolved into one capable of providing
    not only television service, but internet access and telephone
    20
    Professor Parsons teaches telecommunications at the College of Communi-
    cations, Penn State University. He is the author of several books and articles
    about the cable television industry.
    Cite as 
    356 Or 282
     (2014)	317
    (VOIP) services as well. His testimony about that evolution
    is consistent with what treatises in the field document.21
    As Professor Parsons explained, the first docu-
    mented cable television service anywhere in the nation was
    in Astoria, Oregon, in 1948. It consisted of a simple coaxial
    cable run by Ed Parsons (no relation to Professor Parsons)
    to his apartment from an antenna placed where it could pick
    up a weak over-the-air television signal broadcasted from
    Seattle. Mr. Parsons boosted the signal and was able to
    get reception on his television as a result. Francis Murphy,
    Behind the Mike, The Oregonian 32 (Sept 13, 1967). When
    he tired of having friends and neighbors constantly coming
    to his apartment to watch television, Mr. Parsons expanded
    his system by stringing coaxial cable from home to home to
    carry the signal to his neighbors. 
    Id.
    That ushered in the first evolutionary period for
    cable television, which Professor Parsons described as
    lasting from about 1950 to 1975. During that time, cable
    television was principally in the business of transmitting
    over-the-air broadcast television, primarily in rural areas
    that did not receive clear broadcast signals. The technology
    used was similar to Ed Parsons’s system. Essentially, cable
    television providers picked up broadcast signals with an
    antenna and distributed that signal into a cable network,
    often manipulating the signal by amplifying it to make it
    stronger, filtering out unwanted signals, and combining sig-
    nals from different sources into a composite signal for dis-
    tribution. Walter S. Baer, Cable Television: A Handbook for
    Decisionmaking, R-1133-NSF, NSF/RA/S-73-002 at 13-15
    (1973). Throughout that first evolutionary phase, signals in
    cable systems moved predominantly in one direction—from
    the service provider to the customer. Id. at 25. Two-way
    service was technically possible; coaxial cable was capable
    of sending signals, voice, video, and even coded data in the
    opposite direction, from the customer back to the service
    provider. Id. But such services were essentially in prototype
    form and not in general use within the industry. Id. Cable
    television remained a small-scale business because there
    21
    Our description is taken from the testimony of Parsons and other expert
    witnesses who were called at the trial before the Tax Court, except where other
    sources are cited.
    318	                          Comcast Corp. v. Dept. of Rev.
    was no demand for it in more urban and metropolitan areas
    that were served by over-the-air broadcast television.
    The demand for cable television changed, however,
    when Home Box Office (HBO) began distributing its pro-
    gramming by satellite in 1975. HBO’s innovation marked
    the beginning of the second evolutionary period for cable
    television. By contracting with HBO to distribute its pro-
    gramming by cable, the industry had something to offer
    customers in urban and metropolitan areas that they could
    not get for free over the public air waves. In the words of
    Professor Parsons, HBO’s availability through cable televi-
    sion “change[d] the nature of the industry,” creating the eco-
    nomic incentive for new program providers to enter the mar-
    ket (e.g., MTV, CNN, ESPN) and for the industry to expand
    and develop the infrastructure needed to meet demand. The
    second evolutionary period continued into the early to mid-
    1990s, during which cable television developed into a large-
    scale and “very, very successful” business.
    The cable industry entered its third evolutionary
    period—which it remains in today—in the mid-1990s with
    the migration from analog to digital technology. As a result
    of that migration, the cable industry was able to offer its
    customers enhanced television service in the form of more
    channels and higher quality images (so-called “high defi-
    nition television”), as well as new capabilities—such as on-
    demand programming sent to the customer at the custom-
    er’s request—that were not possible with conventional ana-
    log technology. More than that, though, the industry was
    able to expand into “new business lines.” Harnessing the
    same digital infrastructure used for transmitting television
    and video programming to its customers, the cable industry
    could provide its customers the additional services of broad-
    band internet access and telephone via internet (VOIP) ser-
    vices, either separately or as a bundled package. When the
    regulatory barriers to competition within the telecommuni-
    cations field began to give way in the mid-1990s, so that the
    cable industry could compete with the telephone industry
    and vice versa, and both could meet the growing demand for
    internet access, the result was “profound,” to quote Professor
    Parsons. In effect, digital technology caused a “convergence”
    of what had once been separate services and industries.

    356 Or 282
     (2014)	319
    Until that convergence occurred, the technical
    platforms used by the telephone, telegraph, and television
    industries were different, because different platforms were
    best suited to the particular content to be transmitted. As
    a result, voice transmission services were primarily the
    domain of the telephone companies; digital signal transmis-
    sion services (used principally for text) were primarily the
    domain of the now-nonexistent telegraph services; and video
    was primarily the domain of the broadcast and cable televi-
    sion businesses. See generally Niloufer Selvadurai, Meeting
    the Digital Challenge—The Need to Extend the Parameters of
    Reform, 16 J L Inf & Sci 92, 102-03 (2005) (describing how
    the traditional world of communications required distinct
    infrastructures for different communication services). But
    with digital technology, those content distinctions became
    meaningless.
    Now, with digital transmission of content, the con-
    tent is all the same—it is all digital data, encoded by special-
    ized equipment at one end for high-speed transmission, and
    decoded by specialized equipment at the other end so that
    it is in useful form. Professor Thinh Nguyen, an engineer-
    ing and computer science expert who testified at trial for
    the department, explained that, in a digital system, all data
    is a collection of “bits”—that is, zeros and ones—regardless
    of whether it is video, voice, or some other original content.
    The only significant difference is in how the bits are coded
    for efficient transmission. Video, for example, because of the
    massive amount of bandwidth it consumes, requires special
    compression to avoid delays that would make playback jit-
    tery or otherwise unacceptable. And although voice requires
    far less bandwidth than video, the protocols used to com-
    press and encode it are “more stringent” so that it has prior-
    ity in the transmission, because humans are psychologically
    intolerant of significant delay (i.e., more than 100 millisec-
    onds) in conversational speech.
    The technological convergence brought about by the
    migration to digital transmission was not unforeseen; it just
    took time to come about, in part because federal regulatory
    policy has been uneven. For example, in a 1999 congressional
    hearing on data services within the telecommunications field,
    320	                             Comcast Corp. v. Dept. of Rev.
    Representative Markey, a long-time member of the House
    of Representatives Subcommittee on Telecommunications,
    Trade, and Consumer Protection (and, as of 2013, a Senator),
    recounted the subcommittee’s “long history with the devel-
    opment of competitive data services” and gave an over-
    view of that history at the outset of the hearing. Hearing
    on Deployment of Data Services, House Committee on
    Commerce, Subcommittee on Telecommunications, Trade,
    and Consumer Protection, 106th Cong, 1st Sess, 3 (June
    24, 1999). In particular, Representative Markey described
    hearings that he had presided over in the 1980s when the
    subcommittee, with the goal of shaping regulatory policy,
    took testimony on the technological convergence that broad-
    band internet and digital networks would bring about. He
    explained:
    “The computer industry was invited to give us its views
    [on regulatory policy] as well. We heard testimony from
    John Scully of Apple; Mitch Kapor, the founder of Lotus,
    John Gage of Sun Microsystems. We were told to get digi-
    tal; that we were in a period of convergence; that a bit is a
    bit is a bit. It didn’t matter if it was a voice bit, a data bit,
    a movie bit, a music bit, a fact bit: all bits could flow over
    the digital networks and use digital technology. And this
    subcommittee got digital. We began to foster national pro-
    posals to deal with the communications convergence.”
    Id. at 4. That led Representative Markey to express his sur-
    prise that, in 1999, not everyone was prepared to recognize
    the realities of the technological convergence that by then
    had firmly taken hold:
    “Our efforts on all these issues eventually bore fruit.
    We legislated in the midst of this digital convergence and
    enacted the landmark Telecommunications Act of 1996.
    That act broke down historic barriers to competition and
    was designed to unleash a digit[al] free-for-all across all
    market sectors and industries. Central to the act was the
    notion that we would treat all entities based upon the ser-
    vices that they were providing and neither based upon their
    pedigree as a cable company or phone company nor on the
    particular type of facility used to deliver this service.
    “With all this history in mind, one can imagine my sur-
    prise when I was told by someone recently that the Telecom
    Cite as 
    356 Or 282
     (2014)	321
    Act was only about voice. Simply competition for voice bits.
    There are apparently many people in the industry suffer-
    ing from the same bout of telecommunications amnesia.
    Some people now seem to be saying that a bit is a bit is a
    bit, but some bits are more special than other bits. Rather
    than communications convergence, people are proposing
    digital divergence, proposing to rip data bits out of the bit
    stream and treat them differently from voice bits. There
    are also suggestions that identical telecommunications ser-
    vices offered over different facilities should be treated dif-
    ferently. How very undigital.”
    Id. at 4-5. However well federal regulatory policy has or has
    not responded to the convergence brought about by digital
    transmission, that convergence—as a fact of technological
    life—has occurred.22
    22
    In 2006, for example, the Senate Committee on Commerce, Science and
    Transportation held 14 hearings to take testimony from (among others) the wired
    and wireless telephone, cable, internet, and satellite industries on various com-
    munication issues. One of those hearings was devoted entirely to the “phenom-
    enon of convergence” and the continuing challenge of setting federal regulatory
    policy for industries that were no longer meaningfully distinguishable in the
    services they provide. See generally Hearing on Competition and Convergence,
    Senate Committee on Commerce, Science, and Transportation, 109th Cong, 2d
    Sess, 1-2 (Mar 30, 2006) (statement of Senator Ted Stevens, Chair). As regula-
    tors, legislators, and academics alike persistently observe, federal regulatory pol-
    icy has not yet come close to meeting that challenge. See generally, e.g., Kathleen
    Q. Abernathy, The Journey to Convergence: Challenges and Opportunities, 
    12 CommLaw Conspectus 133
    , 133 (2004) (Commissioner, FCC) (“Formerly dis-
    tinct categories of communications services are collapsing into one as voice,
    data, and video are all transmitted via digital bits” so that FCC has become
    “increasingly aware in recent years that this technological and marketplace con-
    vergence demands fresh thinking by regulators.”); Rob Frieden, Adjusting the
    Horizontal and Vertical in Telecommunications Regulation: A Comparison of the
    Traditional and a New Layered Approach, 55 Fed Comm L J 207, 208 (2003)

    relatively static assumptions about the industrial organization of telecommuni-
    cations and information processing”); Senator Ted Stevens, The Internet and the

    policies have led to unnatural migration of telecommunication services to pref-

    tled successfully with realities of convergence in setting state taxation policies.

    Law of the Committee of the Judiciary, Serial No 109-120, June 13, 2006, 17

    Legislators, Steven Rauschenberger) (testifying that convergence has blurred
    distinctions between telephone, internet, cable, wireless, satellite, and other
    communications services, with the troubling result that “similar services can be
    delivered by networks that are taxed very differently”).

    B.  Comcast’s Internet Access and Cable Television Services
    That background brings us to the service-specific
    dispute in this case: Are Comcast’s internet access or cable
    television services “data transmission services” within the
    meaning of ORS 308.505(2)? More specifically, are they
    services that provide the means for transmitting electroni-
    cally coded information between computers or computer-like
    devices? The record before us answers that question unequiv-
    ocally in the affirmative for both services. Although we need
    not delve into the more complicated aspects of the technol-
    ogy involved for either service, it is worthwhile to describe in
    general terms how each service entails data transmission as
    we have interpreted it for purposes of central assessment.
    1.  The Technology Used in Comcast’s Cable Tele-
    vision Service
    Comcast’s cable television begins with video pro-
    gramming that Comcast obtains from three basic sources:
    over-the-air broadcasts; programming transmitted to
    Comcast via satellite; and “direct studio feed” over fiber optic
    cable. Comcast then combines its source video program-
    ming at a location called a “headend facility,” where it is
    processed in a way that results in the actual programming,
    menus, guides, and other services delivered to the customer.
    Although the way that Comcast compresses and trans-
    mits data across its network is proprietary, certain aspects
    of it necessarily conform to industry standards.23 Thus,
    Professor Nguyen was able to explain certain aspects of
    Comcast’s cable television service with confidence. Comcast
    uses a compression protocol (MPEG-2) to transmit data for
    purposes of its video services. For its regular programming,
    the data is transmitted from Comcast’s “headend” facility
    23
    Because of their proprietary nature, the exact protocols that Comcast uses
    and how it combines its various sources of video were held confidential during
    the trial before the Tax Court. The department therefore had to make its case
    by presenting expert testimony as to how digital information—from an electrical
    engineering standpoint—must be processed and transmitted through the kind of
    infrastructure that Comcast uses (a combination of fiber optic and coaxial cable)
    if it is to interconnect, as Comcast’s system does, with the internet and other com-
    munication services, such as satellite transmission. The Tax Court ultimately
    admitted the testimony of the department’s expert, Professor Nguyen, explain-
    ing: “I understand your testimony to be that to some extent, given industry stan-
    dards and given industry requirements, you can almost infer backwards [what
    Comcast] must be doing in order for the whole thing to work.”
    Cite as

     (2014)	323
    to the customer’s home. For on-demand movies and other
    video programming, the data is stored on servers, which are
    “high end” specialized computer devices that store massive
    amounts of data and are capable of transmitting that data
    to individual customers on request.
    For a customer to view the video programming, the
    data generally first goes through a receiver in the form of
    a “set top box,” which is connected to the customer’s televi-
    sion.24 In effect, a set top box is a computer or computer-like
    device with a microchip in it that gives it its functionality.
    The primary function of the set top box is to take compressed
    video data transmitted through Comcast’s infrastructure
    and transform it into a signal that is usable at the customer’s
    end. Set top boxes also, depending on the model of the box,
    control the delivery of enhanced television services. Thus,
    the model of set top box determines whether a customer will
    receive high definition television service, on-demand pro-
    gramming, or have the capability to record programming
    for later viewing (digital video recording, or “DVR”). A set
    top box “off the shelf” can do nothing, however. It is, in the
    words of one of Comcast’s experts, “a dead device.” Comcast
    must first direct “command-line code” to the box for the cus-
    tomer to be able to view any television programming or have
    access to enhanced television services.
    2.  The Technology Used in Comcast’s Internet
    Access Service
    Comcast’s internet access service provides high-
    speed internet access to customers, thus permitting them, as
    described by one of Comcast’s experts, “to be able to transmit
    and receive whatever they are asking or receiving to either a
    business, a service, or to another person’s home.” The server
    requires a cable modem at the customer’s end, which sends
    and receives signals to Comcast’s headend facility over the
    24
    Although the record is sketchy on the point, in some localities, Comcast
    evidently uses a blend of analog and digital signals and delivers “basic” program-
    ming (principally over-the-air broadcasts that Comcast is obligated to carry)
    without a set top box of any kind. In those localities, customers who subscribe
    to only basic service attach the coaxial cable carrying the signal directly to their
    televisions. The record suggests that in most localities, however, the signal for
    basic service is transmitted in digital form and a set top box is required to con-
    vert it into analog form for use.
    324	                                    Comcast Corp. v. Dept. of Rev.
    same infrastructure used for Comcast’s cable television and
    VOIP (telephone) services, coding and decoding them in
    the process. 25 After the data is transmitted to the headend
    facility, Comcast “distribute[s] it out through a series of net-
    works and routers and switches, out into the * * * worldwide
    web.” For all data sent and received as part of its internet
    access service, Comcast uses a standard digital data pro-
    tocol (“DOCSIS,” which stands for “data over cable service
    interface specification”). Using Comcast’s internet access
    service to send and receive data, customers can browse the
    web, transfer files using computer file transfer protocols,
    exchange e-mail, and generally avail themselves of what-
    ever information, services, and content is available via the
    internet. To do so, a customer must have a personal com-
    puter or other computer-like device capable of making use of
    the data that Comcast transmits through the cable modem.
    3.  Are Comcast’s Services “Data Transmission
    Services”?
    Those descriptions of Comcast’s services are con-
    cededly rudimentary and do not convey the technological
    complexity involved for either Comcast’s cable television or
    internet access services. But they are sufficient for the issue
    before us. They demonstrate what Comcast does not really
    contest in this case—that both services fundamentally
    transmit information and other content in electronic form
    between computers or computer-type devices capable of cod-
    ing and decoding that content into useful form. The protocols
    and compression algorithms used, along with other aspects
    of the transmission, are complex and technical. Comcast
    simply has not disputed, however, that what it transmits
    over its cable network is predominantly digital data in the
    form of bits. The fact that the content originates as video,
    converts to bits for transmission, and then at some point
    is video again does not make Comcast’s service something
    other than one that transmits data. There are not, to borrow
    from Representative Markey, voice bits, data bits, movie bits,
    music bits, or fact bits. They are all just bits, compressed and
    25
    The label “modem,” Professor Nguyen explained, comes from the terms
    “modulation” and “demodulation,” which refer to a complicated process by which
    signals or data are put into a form for efficient and reliable transmission over a
    medium, such as fiber optic or coaxial cable.

    organized for efficient and reliable transmission through a
    digital infrastructure. It is only when a computer or com-
    puter-like device on the receiving end of the transmission
    converts them into a useful form that the original content
    (such as voice, video, text) is available to the recipient. So
    understood, the transmission service that Comcast provides
    for both cable television and internet access is the essence of
    what the legislature understood data transmission services
    to be: “the transmission over telephone facilities or micro-
    wave facilities [or other means] of data between computers
    primarily, or data from a computer terminal into a com-
    puter, or other nonverbal kind of data communication.” Tape
    Recording, Senate Revenue Committee, SB 81, Feb 9, 1973,
    Tape 10, Side 2 (statement of Victor Bredehoeft, Department
    of Revenue).
    C.  Comcast’s Contrary Arguments
    Comcast nevertheless makes a set of arguments in
    favor of either a more narrow interpretation of “data trans-
    mission services” or a more narrow application to Comcast’s
    cable television and internet access services. We discussed
    and rejected Comcast’s principal argument earlier—that
    the legislature intended to reach only microwave private
    line transmission of intracompany business data. Comcast’s
    remaining arguments are better addressed against the
    backdrop, set out above, of the evolution of the cable indus-
    try and the technological convergence that has occurred in
    the telecommunications field.
    1.  The Legislature’s Silence on Cable Television
    Comcast takes the position that, however data
    transmission services is defined and whatever else it may
    include, the legislature could not have intended it to include
    Comcast’s cable television service, because no one in the
    1973 hearings mentioned cable television. That omission
    is significant, Comcast argues, because cable television by
    then was a well-established service in Oregon and through-
    out the nation. It follows, contends Comcast, that the legis-
    lature intended to leave the cable television industry subject
    to local assessment only. According to Comcast, because the
    legislature has never amended the statutes to specifically
    address cable television services or to otherwise make those
    326	                          Comcast Corp. v. Dept. of Rev.
    services expressly subject to central assessment, the phrase
    “data transmission services” cannot extend to cable televi-
    sion, at least not consistently with the legislature’s intent.
    The simple answer to Comcast’s argument is that
    the cable television service that it now provides is not the
    same service that the cable industry was delivering in
    1973. When the legislature amended the statutes in 1973,
    the demands for data transmission were nascent. Although
    nothing in the record before us establishes precisely how
    cable television services were delivered in Oregon in 1973,
    Professor Nguyen’s uncontradicted testimony establishes
    that they were not delivered through a digital network that
    sent data to and from cable modems and through set top
    boxes that convert compressed digital bits to and from ana-
    log and other usable signal forms. It is unsurprising that
    no one in the legislative hearings discussed cable television
    given that the cable television industry was not then deliv-
    ering its content through a data transmission service as the
    legislature understood that terminology.
    Sometime between 1973 and 2009, when the depart-
    ment first centrally assessed Comcast’s cable television ser-
    vice, the cable television industry—along with the rest of
    the telecommunications industry—underwent a revolution-
    ary transformation with the advent of high-speed internet
    and digital networks. Put bluntly, since then, everything
    has “gone digital,” cable television included. Voice communi-
    cation is largely accomplished with data transmission; tele-
    vision and video communication are largely accomplished
    with data transmission; text communication is largely
    accomplished with data transmission; information commu-
    nication is largely accomplished with data transmission.
    The legislature did not make the original or eventual con-
    tent on the sending and receiving ends (e.g., voice, video,
    text, information) a defining characteristic of what qualifies
    as a data transmission service. The defining characteristic
    is, instead, the format of the data transmitted. If the data is
    in the form of electronic information coded for and transmit-
    ted from one computer or computer-like device to another—
    as Comcast’s television cable service now unquestionably
    entails—it does not matter that, in 1973, the service was of
    a different nature and went unmentioned by the legislature.
    Cite as 
    356 Or 282
     (2014)	327
    Nor does it matter that the legislature in 1991
    declined to amend the description of “communication” ser-
    vices in ORS 308.505(2) to expressly include cable services.
    Specifically, Comcast points to House Bill (HB) 2556 (1991),
    which would have expressly added cable television to the cen-
    tral assessment scheme by adding it to the list of businesses
    and services that the term “communication” includes. HB
    2556 did not make it out of committee and was not enacted
    into law. The Tax Court, for its part, found that history dif-
    ficult to ignore, noting that “[t]he actions and words of the
    legislators and of the persons appearing before the legisla-
    ture [were] not consistent with a conclusion that cable tele-
    vision was already subject to central assessment under the
    statute[.]” Comcast Corp., 20 OTR at 324.
    There are two answers to Comcast’s reliance on
    that history. One is the answer we have given in other cases:
    What later legislators thought is irrelevant to what an ear-
    lier legislature intended with an enactment, especially in
    the context of a later bill that never became law. DeFazio
    v. WPPSS, 
    296 Or 550
    , 561, 679 P2d 1316 (1984) (“The
    views legislators have of existing law may shed light on a
    new enactment, but it is of no weight in interpreting a law
    enacted by their predecessors.”); Hilton v. MVD, 
    308 Or 150
    ,
    156, 775 P2d 1378 (1989) (“A later legislature’s failure to
    change a previously enacted statute is not part of the legis-
    lative history of that statute[.]”).
    The second answer is specific to this case: The failed
    1991 bill may show that, at that point in time, legislators
    were not inclined to list the specific service of cable television
    as a “communication” service along with “data transmission
    services” and the others in ORS 308.505(2). That choice says
    nothing, however, about whether cable television qualified
    as a “data transmission service” as of 1991 or whether leg-
    islators thought that cable television should be specifically
    excluded if it did. As the testimony in this case suggests,
    cable television likely had not migrated by 1991 to a digital
    network platform and was not then delivering television pro-
    gramming through data transmission. In this case, we need
    not determine whether, before 2009, Comcast was a “commu-
    nication” service within the meaning of ORS 308.505(2) and
    ORS 308.515. See 356 Or __ n 6). The dispositive question
    328	                          Comcast Corp. v. Dept. of Rev.
    before us is whether, as of 2009, Comcast’s cable television
    service is a “data transmission service” within the meaning
    of ORS 308.505(2). Our conclusion that it is now a data trans-
    mission service is a complete answer, regardless of what the
    answer might have been in 1991.
    2.  The Legislature’s Silence on Internet Access
    Service
    Comcast makes a related argument in connection
    with its internet access service. Specifically, it argues that
    the legislature could not have intended internet access ser-
    vice to be included in “data transmission services” because
    that service did not exist as of 1973. Most of Comcast’s
    points in that regard circle back to its premise, which we
    have rejected, that the legislature intended “data transmis-
    sion services” to describe the service of private line micro-
    wave transmission of intracompany business data. From
    that premise, Comcast argues that the legislature contem-
    plated only a “discrete service” with a particular “function-
    ality,” and internet access is simply a “portal” service, one
    that gives users “myriad functionalities and capabilities”
    beyond anything that the legislature contemplated in 1973.
    Comcast emphasizes that it does not “own the internet,” and
    no one does. Rather, Comcast urges, the internet consists of
    individually owned pieces of a network interconnected with
    each other through protocols and transmission standards
    that make the interconnection possible.
    Just as that argument did not detain the Tax Court,
    it does not detain us. Comcast makes no effort to argue that,
    for its piece of the internet network (which it concedes it
    must maintain to provide internet access service), it does
    not in fact transmit to and from its customers information
    of all kinds (such as voice, video, and text) in the form of
    data that must be processed at both ends by computers or
    computer-like devices. Comcast’s only argument is that the
    legislature did not foresee the existence of internet access
    services, so even if internet access service is in a technical
    sense a data transmission service, it is not subject to central
    assessment because that precise application of the service
    was not within the legislature’s contemplation in 1973.
    Cite as 
    356 Or 282
     (2014)	329
    As we have already described at length, however,
    the 1973 hearings establish that the legislature was antic-
    ipating future developments—even if it did not have a con-
    crete vision of that future—by amending the statute to
    expressly include the emerging service of data transmis-
    sion; the amendment was not intended to reach only the
    particular use (microwave private line business data trans-
    mission) that prompted the legislature’s attention. The fact
    that internet access service did not exist in 1973 does not
    place it beyond the reach of the policy that the legislature
    enacted. If it qualifies as a data transmission service within
    the meaning of ORS 308.505(2)—and we conclude that it
    does—it is subject to central assessment whether it has been
    in existence for 40 years or 40 days.
    3.
    The Specter of Unconstitutionality
    Comcast’s final argument is that, if the phrase
    “data transmission services” is interpreted broadly, it will
    run into constitutional problems, a fact that should counsel
    in favor of interpreting it narrowly. Comcast contends that
    too broad a definition of “data transmission services” will
    sweep up all forms of communication that involve, in some
    way or another, the transmission of data. Comcast warns
    that magazines, newspapers, online legal research provid-
    ers, radio stations, billboards, and over-the-air broadcasters
    could all be subject to central assessment as “data trans-
    mission services,” reasoning that each involves the trans-
    mission of data in the broadest sense of the word—that is,
    the communication of information. In Comcast’s view, that
    would place the department in the position of picking “win-
    ners and losers” in terms of who is centrally assessed and
    who is not. According to Comcast, for the department to play
    that role would violate Article I, section 32 (taxes may not be
    imposed without the consent of the people), and Article III,
    section 1, of the Oregon Constitution (separation of powers).
    Although that argument gave the Tax Court pause,
    it should not have. Comcast’s argument depends on the
    term “data” meaning information of all kinds, akin to the
    definition of the singular form of the word “datum” that we
    quoted earlier. But that is not the meaning that the legis-
    lature intended. Rather, the full phrase “data transmission
    330	                                    Comcast Corp. v. Dept. of Rev.
    services” has a technical meaning drawn from the telecom-
    munications field. The phrase therefore means something
    more exacting—it refers to the service of transmitting coded
    electronic information between computer and computer-like
    devices. It is difficult to see—and Comcast does not explain—
    how many of the “forms of communication” that Comcast
    fears will be swept into central assessment would qualify
    under that definition. For example, publishing and send-
    ing a magazine through the mail or delivering a newspaper
    to the front step of a person’s home may be ways of trans-
    mitting information from one place to another. But neither
    example is a “data transmission service” within the mean-
    ing of ORS 308.505(2). If, instead, the magazine or newspa-
    per is put into digital form and made available for viewing
    or downloading via the internet, the publication then is in
    the form of data, as required by ORS 308.505(2). But the
    publisher is not providing the service of transmitting the
    data so that it can be read on someone’s computer or tablet
    electronic reading device—that service likely is provided by
    Comcast or some other for-fee internet access service. The
    same is true of online research and myriad other kinds of
    information and content accessible through the internet.26
    In all events, the issue before us is only whether
    Comcast’s internet access and cable television services
    qualify as “data transmission services,” not whether other
    services do. Comcast’s examples of the publications and
    information services that it fears will be swept into central
    assessment are exaggerated and do not persuade us that the
    phrase “data transmission services” is so broad that it poses
    constitutional concerns.27
    26
    As for Comcast’s other examples, billboards seem like a less than seri-
    ous example. Over-the-air broadcast television and radio are more credible ones.
    Although our resolution in this case will provide guidance for future applications
    of ORS 308.505(2), we resolve no dispute other than the ones before us. We note
    only that over-the-air broadcast television and radio involve a means of commu-
    nication that differs in significant ways from the services before us. Among other
    things, no subscriptions are required; viewers do not pay a fee to the over-the-air
    broadcaster to view or listen to the programming. Nor does the broadcaster con-
    trol who listens to or views the programming. Rather, the broadcaster releases
    the signal or data into the public airwaves in a form that permits all persons
    within range to view or listen to the broadcast, if they have the equipment needed
    to receive the signal or data through the airwaves.
    27
    Other than the examples that it lists, Comcast devotes no analysis to its
    constitutional concerns. Without more development of the vague constitutional

    D.  The Tax Court’s Reasoning on Cable Television
    As we have described, the Tax Court determined
    that Comcast’s internet access service is a data transmis-
    sion service, but its cable television service is not. In reach-
    ing that conclusion, the Tax Court adopted an interpreta-
    tion of “data transmission services” that neither Comcast
    nor the department had proposed, and that neither defends
    on appeal. Specifically, the Tax Court determined that, by
    referring to data transmission as a “service,” rather than
    to data as a commodity, ORS 308.505(2) reaches only busi-
    nesses that, for a fee, take data owned or generated by one
    party and move it to another party. Comcast Corp., 20 OTR
    at 332. The Tax Court concluded that Comcast’s internet
    access service therefore is a data transmission service, rea-
    soning that the data that flows in the internet access ser-
    vice is “not data created by Comcast or data as to which
    [Comcast] has publication rights.” Id. at 335. But the court
    reached the opposite conclusion for Comcast’s cable televi-
    sion service, which it concluded principally transmits to cus-
    tomers content in the form of data (e.g., television program-
    ming, movies, and special channels by subscription) that
    Comcast itself owns or otherwise has the right to transmit.
    Id. at 333. The Tax Court explained:
    “Comcast here sells content to its customers and delivers
    the content over its system. A retailer sells products to cus-
    tomers and may deliver those through the use of railroads
    or air express. The mode of delivery does not convert the
    retailer into a railroad under subsection (1)(a) of the stat-
    ute or an air express company under subsection (1)(g) of
    the statute.”
    Id. at 331.
    The flaw in the Tax Court’s reasoning is revealed
    in that quotation: A retailer who sells products to customers
    and uses the railroad to deliver them does not (at least in the
    Tax Court’s example) own the railroad. The railroad is still
    a railroad, and remains subject to central assessment. That
    principles to which Comcast alludes, we decline to address Comcast’s argument
    beyond pointing out that it is not based on “data transmission services” as we
    have interpreted that phrase and the examples that Comcast cites do not demon-
    strate that our interpretation is unmanageably broad.
    332	                                   Comcast Corp. v. Dept. of Rev.
    would remain true even if the railroad were to use its own
    transportation service to transport retail goods that it owns.
    Said another way, the fact that the railroad is engaged in
    dual businesses (retail and transportation) does not cause
    it to lose its character as a railroad. The same is true of
    Comcast. Here, the fact that it is in the business of both sell-
    ing video content and transmitting it in digital form to its
    customers does not divest Comcast of its character as a data
    transmission service.
    Nor does the context provided by the central assess-
    ment statute as a whole support the Tax Court’s reasoning.
    “Communication” services are listed in common with ser-
    vices such as heating, gas, and electricity. ORS 308.515(1).
    Those services all involve selling customers not only the ser-
    vice of transmission, but also the commodity being trans-
    mitted. We fail to see in the statutory text or its context
    any basis to conclude that the legislature intended to dif-
    ferentiate data transmission services based on whether the
    data that the customer receives is data directed to it by the
    service provider itself or by some third party. In addition,
    we are not as confident as the Tax Court was that the dis-
    tinction would aid Comcast in this case, because the record
    shows that a significant portion of the data that Comcast’s
    cable television service transmits is, in fact, digitized con-
    tent owned or generated by others.28 Fundamentally, how-
    ever, the distinction makes no difference under the statute.
    E.  Summary
    As we have explained, based our analysis of the
    text, context, legislative history, and technical meaning
    of “data transmission service,” we interpret that phrase to
    extend to any service that provides the means for the trans-
    mission of electronically coded information between com-
    puters or computer-like devices. If the service does that,
    it is a data transmission service regardless of the original
    28
    The Tax Court did not take into account a significant aspect of Comcast’s
    cable business: advertising that third parties pay Comcast to include in its pro-
    gramming, which Comcast itself has characterized as a significant portion of
    its overall revenue. For example, Comcast took in $1.5 billion from advertising
    in 2008. The record also establishes that Comcast neither owns nor licenses the
    so-called “must carry” content, which consists of, as characterized in Comcast’s
    2008 SEC Annual Report, “the programming transmitted by most local commer-
    cial and noncommercial television stations.”
    Cite as 
    356 Or 282
     (2014)	333
    nature of the content that is converted into digital form for
    transmission. That is, it does not matter if the data has been
    converted from voice to bits, video to bits, text to bits, or
    for that matter, atoms to bits.29 For purposes of our inter-
    pretation, bits are bits. Likewise, it does not matter if the
    means of transmission is fiber optic cable, coaxial cable,
    microwave or other wireless conduit, the wired network tra-
    ditionally used for telephone communication, or a means of
    transmission not yet in use or conceived. What matters is
    that the information or other content being transmitted is
    in the form of data. Finally, it does not matter that the ser-
    vice preexisted the 1973 amendments, and only since then
    has evolved to become a data transmission service, or that it
    postdates those amendments and is an unprecedented use
    of data transmission services. The evidence in the record
    about the nature of Comcast’s internet and cable transmis-
    sion services is effectively undisputed and establishes that,
    within the meaning of ORS 308.505(2), both services are
    “data transmission services.”
    IV.  REMAINING ISSUES
    The department raises two additional issues
    under its assignments of error. The first arises under ORS
    308.510(5), which provides that property used in both a cen-
    trally assessed business and a non-centrally assessed busi-
    ness is subject to central assessment if its primary use is in
    the centrally assessed business.30 As we earlier described,
    Comcast uses the same basic infrastructure for both its
    29
    For example, in existence now and on the horizon for widespread future
    use is the technology of so-called “3D printing.” That development has already
    made it possible to turn atoms into bits and bits back into atoms by digitizing the
    information needed to do “print” (that is, construct, assemble, manufacture, and
    replicate) everything from machine parts, to works of art, to food and medicine,
    and to body parts. See generally Lucas S. Osborn, Regulating Three-Dimensional
    Printing: The Converging Worlds of Bits and Atoms, 51 San Diego L Rev 553
    (2014) (describing wide range of current and future uses for 3D printing, along
    with legal issues that 3D printing presents); see also Hod Lipson and Melba
    Kurman, Fabricated: The New World of 3D Printing (2013) (canvassing current
    and anticipated uses of 3D printing technology).
    30
    ORS 308.510(5) states, in relevant part:
    “Property found by the department to have an integrated use * * * in more than
    one business, service or sale, where at least one such * * * service * * * is one
    enumerated in ORS 308.515, shall be classified by the department as being
    within or without the definition of property under [ORS 308.510(1)] accord-
    ing to the primary use of such property, as determined by the department.”
    334	                          Comcast Corp. v. Dept. of Rev.
    cable television and internet access services. Because the
    Tax Court concluded that Comcast’s internet access service
    is a data transmission service and its cable television service
    is not, the Tax Court had to further decide which service
    was the primary use of Comcast’s property. The Tax Court
    concluded that the property’s primary use was for Comcast’s
    cable television service and, therefore, the property was
    not subject to central assessment at all. Comcast Corp., 20
    OTR at 337. The department challenges that conclusion,
    asserting that the Tax Court’s methodology for determin-
    ing primary use was flawed. We need not reach that issue,
    however. Because we have determined that both Comcast’s
    cable television and internet access services are data trans-
    mission services, the primary use of Comcast’s property is
    no longer an issue in the case.
    The converse is true of the department’s second
    argument, however. That argument presents an issue that
    was moot under the Tax Court’s resolution of the case, but is
    not moot under ours.
    Specifically, before the Tax Court, Comcast chal-
    lenged the maximum assessed value (MAV) that the depart-
    ment had placed on Comcast’s centrally assessable prop-
    erty for the 2009-2010 tax year. Briefly described, Comcast
    argued that the amount of the assessment exceeded the
    three-percent cap set under Measure 50. See Or Const,
    Article XI, § 11(1)(b) (a “property’s maximum assessed value
    shall not increase by more than three percent from the pre-
    vious tax year”). The department responded to that chal-
    lenge by arguing that Comcast’s centrally assessed property
    falls within the exception for “new property or new improve-
    ments to property.” Or Const, Article XI, § 11(1)(c)(A).
    The department asks us to reach and resolve that
    dispute, even though the Tax Court did not, urging that it
    presents a purely legal question that this court appropri-
    ately may resolve on appeal. Regardless of whether the
    department is correct in characterizing the issue as purely
    one of law, we decline the department’s invitation. The issue
    entails an intricate question of tax law, one that involves
    assessment procedures and practices that the Tax Court
    deals with frequently. The statutes that provide for tax

    cases to be resolved first by the Tax Court, before coming to
    this court on appeal, implicitly recognize the value to this
    court of the Tax Court’s resolution of tax disputes in the first
    instance. The MAV issue that the parties dispute is one that
    is appropriately resolved first by the Tax Court.
    The decision of the Tax Court is reversed, and the
    case is remanded to that court for further proceedings.
