delivered the opinion of the Court.
The plaintiffs in this litigation, creators and producers of televised programs copyrighted under the provisions of the Copyright Act of 1909, as amended, 17 U. S. C. § 1 et seq., commenced suit in 1964 in the United States District Court for the Southern District of New York, claiming that the defendants had infringed their copyrights by intercepting broadcast transmissions of copy*397righted material and rechanneling these programs through various community antenna television (CATV) systems to paying subscribers.1 The suit was initially *398stayed by agreement of the parties, pending this Court’s decision in Fortnightly Corp. v. United Artists Television, 392 U. S. 390. In that case, decided in 1968, we held that the reception and distribution of television broadcasts by the CATV systems there involved did not constitute a “performance” within the meaning of the Copyright Act, and thus did not amount to copyright infringement.2 After that decision the plaintiffs in the present litigation filed supplemental pleadings in which they sought to distinguish the five CATV systems challenged here from those whose operations had been found not to constitute copyright infringement in Fortnightly.3 The District Court subsequently dismissed the complaint on the ground that the plaintiffs’ cause of action was barred by the Fortnightly decision. 355 F. Supp. 618. On appeal to the United States Court of Appeals for the *399Second Circuit, the judgment was affirmed in part and reversed in part, and the case was remanded to the District Court for further proceedings. 476 F. 2d 338. Both the plaintiffs and the defendants petitioned for certiorari, and, because of the seemingly important questions of federal law involved, we granted both petitions. 414 U. S. 817.
I
The complaint alleged that copyright infringements occurred on certain dates at each of five illustrative CATV systems located in Elmira, New York; Farming-ton, New Mexico; Rawlins, Wyoming; Great Falls, Montana; and New York City. The operations of these systems typically involved the reception of broadcast beams by means of special television antennae owned and operated by Teleprompter, transmission of these electronic signals by means of cable or a combination of cable and point-to-point microwave4 to the homes of *400subscribers, and the conversion of the electromagnetic signals into images and sounds by means of the subscribers’ own television sets.5 In some cases the distance between the point of original transmission and the ultimate viewer was relatively great — in one instance more than 450 miles — and reception of the signals of those stations by means of an ordinary rooftop antenna, even an extremely high one, would have been impossible because of the curvature of the earth and other topographical factors. In others, the original broadcast was relatively close to the customers’ receiving sets and could normally have been received by means of standard television equipment. Between these extremes were systems involving intermediate distances where the broadcast signals could have been received by the customers’ own television antennae only intermittently, imperfectly, and sporadically.6
Among the various actual and potential CATV operations described at trial the Court of Appeals discerned, *401for copyright purposes, two distinct categories. One category included situations where the broadcast signal was already “in the community” served by a CATV system, and could be received there either by standard rooftop or other antennae belonging to the owners of television sets or by a community antenna erected in or adjacent to the community. Such CATV systems, the court found, performed essentially the same function as the CATV systems in Fortnightly in that they “no more than enhance the viewer’s capacity to receive the broadcaster’s signals,” 392 U. S., at 399. The second category included situations where the CATV systems imported “distant” signals from broadcasters so far away from the CATV community that neither rooftop nor community antennae located in or near the locality could normally receive signals capable of providing acceptable images.
The Court of Appeals determined that “[w]hen a CATV system is performing this second function of distributing signals that are beyond the range of local antennas, . . . to this extent, it is functionally equivalent to a broadcaster and thus should be deemed to ‘perform’ the programming distributed to subscribers on these imported signals.” 476 F. 2d, at 349. The Court of Appeals found that in two of the operations challenged in the complaint — those in Elmira and New York City — the signals received and rechanneled by the CATV systems were not “distant” signals, and as to these claims the court affirmed the District Court’s dismissal of the complaint. As to the three remaining systems, the case was remanded for further findings in order to apply the appellate court’s test for determining whether or not the signals were “distant.” 7 In No. 72-1633 the plaintiffs *402ask this Court to reverse the determination of the Court of Appeals that CATV reception and retransmission of signals that are not “distant” do not constitute copyright infringement. In No. 72 — 1628, the defendants ask us to reverse the appellate court’s determination that reception and retransmission of “distant” signals amount to a “performance,” and thus constitute copyright infringement on the part of the CATV systems.
II
We turn first to the assertions of the petitioners in No. 72-1633 that irrespective of the distance from the broadcasting station, the reception and retransmission of its signal by a CATV system constitute a “performance” of a copyrighted work. These petitioners contend that a number of significant developments in the technology and actual operations of CATV systems mandate a reassessment of the conclusion reached in Fortnightly that CATV systems act only as an extension of a tele*403vision set’s function of converting into images and sounds the signals made available by the broadcasters to the public. In Fortnightly this Court reviewed earlier cases in the federal courts and determined that while analogies to the functions of performer and viewer envisioned by the Congress in 1909 — that of live or filmed performances watched by audiences — were necessarily imperfect, a simple line could be drawn: “Broadcasters perform. Viewers do not perform.” 392 U. S., at 398 (footnotes omitted). Analysis of the function played by CATV systems and comparison with those of broadcasters and viewers convinced the Court that CATV systems fall “on the viewer’s side of the line.” Id., at 399 (footnote omitted).
“The function of CATV systems has little in common with the function of broadcasters. CATV systems do not in fact broadcast or rebroadcast. Broadcasters select the programs to be viewed; CATV systems simply carry, without editing, whatever programs they receive. Broadcasters procure programs and propagate them to the public; CATV systems receive programs that have been released to the public and carry them by private channels to additional viewers. We hold that CATV operators, like viewers and unlike broadcasters, do not perform the programs that they receive and carry.” Id., at 400-401 (footnotes omitted).
The petitioners claim that certain basic changes in the operation of CATV systems that have occurred since Fortnightly bring the systems in question here over to the broadcasters’ “side of the line.” In particular, they emphasize three developments that have taken place in the few years since the Fortnightly decision. First, they point out that many CATV systems, including some of *404those challenged here, originate programs wholly independent of the programs that they receive off-the-air from broadcasters and rechannel to their subscribers.8 It is undisputed that such CATV systems “perform” those programs which they produce and program on their own; but it is contended that, in addition, the engagement in such original programing converts the entire CATV operation into a “broadcast function,” and thus a “performance” under the Copyright Act. Second, these petitioners assert that Teleprompter, unlike the CATV operators sued in Fortnightly, sells advertising time to commercial interests wishing to sell goods or services in the localities served by its CATV systems. The sale of such commercials, they point out, was considered in the Fortnightly opinion as a function characteristically performed by broadcasters. Id., at 400 n. 28, citing Intermountain Broadcasting & Television Corp. v. Idaho Microwave, Inc., 196 F. Supp. 315, 325. Finally, they contend that by engaging in interconnection with other CATV systems — whereby one CATV system that originates a program sells the right to redistribute it to other CATV systems that carry it simultaneously to their own subscribers — the CATV operators have similarly transferred their functions into that of broadcasters, thus subjecting themselves to copyright infringement liability.9
*405The copyright significance of each of these functions— program origination, sale of commercials, and interconnection — suffers from the same logical flaw: in none of these operations is there any nexus with the defendants’ reception and rechanneling of the broadcasters’ copyrighted materials. As the Court of Appeals observed with respect to program origination, “[e]ven though the origination service and the reception service are sold as a package to the subscribers, they remain separate and different operations, and we cannot sensibly say that the system becomes a ‘performer’ of the broadcast programming when it offers both origination and reception services, but remains a nonperformer when it offers only the latter.” 476 F. 2d, at 347. Similarly, none of the programs accompanying advertisements sold by CATV or carried via am interconnection arrangement among CATV systems involved material copyrighted by the petitioners.10
For these reasons we hold that the Court of Appeals was correct in determining that the development and implementation of these new functions, even though they may allow CATV systems to compete more effectively with the broadcasters for the television market, are simply extraneous to a determination of copyright infringement liability with respect to the reception and retransmission of broadcasters’ programs.
*406Ill
In No. 72-1628 Teleprompter and its subsidiary, Conley Electronics Corp., seek a reversal of that portion of the Court of Appeals' judgment that determined that the importation of “distant” signals from one community into another constitutes a “performance” under the Copyright Act. In concluding that rechanneling of “distant” signals constitutes copyright infringement while a similar operation with respect to more nearby signals does not, the court relied in part on a description of CATV operations contained in this Court's opinion in United States v. Southwestern Cable Co., 392 U. S. 157, announced a week before the decision in Fortnightly:
“CATV systems perform either or both of two functions. First, they may supplement broadcasting by facilitating satisfactory reception of local stations in adjacent areas in which such reception would not otherwise be possible; and second, they may transmit to subscribers the signals of distant stations entirely beyond the range of local antennae.” Id., at 163.
The Court in Southwestern Cable, however, was faced with conflicting assertions concerning the jurisdiction of the Federal Communications Commission to regulate in the public interest the operations of CATY systems. Insofar as the language quoted had other than a purely descriptive purpose, it was related only to the issue of regulatory authority of the Commission. In that context it did not and could not purport to create any separation of functions with significance for copyright purposes.11
*407In the briefs and at oral argument various rationales for the distinction adopted by the Court of Appeals have been advanced. The first, on which the court itself relied, is the assertion that by importing signals from distant communities the CATV systems do considerably more than “enhance the viewer’s capacity to receive the broadcaster’s signals,” Fortnightly, 392 U. S., at 399, and instead “bring signals into the community that would not otherwise be receivable on an antenna, even a large community antenna, erected in that area.” 476 F. 2d, at 349. In concluding that such importation transformed the CATV systems into performers, the Court of Appeals misconceived the thrust of this Court’s opinion in Fortnightly.
In the Fortnightly case the Court of Appeals had concluded that a determination of whether an electronic function constituted a copyright “performance” should depend on “how much did the [CATV system] do to bring about the viewing and hearing of a copyrighted *408work.” 377 F. 2d 872, 877. This quantitative approach was squarely rejected by this Court:
“[M]ere quantitative contribution cannot be the proper test to determine copyright liability in the context of television broadcasting. . . . Rather, resolution of the issue before us depends upon a determination of the function that CATV plays in the total process of television broadcasting and reception.” 392 U. S., at 397.
By importing signals that could not normally be received with current technology in the community it serves, a CATV system does not, for copyright purposes, alter the function it performs for its subscribers. When a television broadcaster transmits a program, it has made public for simultaneous viewing and hearing the contents of that program. The privilege of receiving the broadcast electronic signals and of converting them into the sights and sounds of the program inheres in all members of the public who have the means of doing so. The reception and rechanneling of these signals for simultaneous viewing is essentially a viewer function, irrespective of the distance between the broadcasting station and the ultimate viewer.
In Fortnightly the Court reasoned that “[i]f an individual erected an antenna on a hill, strung a cable to his house, and installed the necessary amplifying equipment, he would not be ‘performing’ the programs he received on his television set,” id., at 400, and concluded that “[t]he only difference in the case of CATV is that the antenna system is erected and owned not by its users but by an entrepreneur.” Ibid. In the case of importation of “distant” signals, the function is essentially the same. While the ability or inclination of an individual to erect his own antenna might decrease with respect to distant signals because of the increased cost of bringing *409the signal to his home, his status as a “nonperformer” would remain unchanged. Similarly, a CATV system does not lose its status as a nonbroadcaster, and thus a “nonperformer” for copyright purposes, when the signals it carries are from distant rather than local sources.
It is further argued that when a CATV operator increases the number of broadcast signals that it may receive and redistribute, it exercises certain elements of choice and selection among alternative sources and that this exercise brings it within scope of the broadcaster function. It is pointed out that some of the CATV systems importing signals from relatively distant sources could with equal ease and cost have decided to import signals from other stations at no greater distance from the communities they serve. In some instances, the CATV system here involved “leapfrogged” nearer broadcasting stations in order to receive and rechannel more distant programs.12 By choosing among the alternative broadcasting stations, it is said, a CATV system functions much like a network affiliate which chooses the mix of national and local program material it will broadcast.
The distinct functions played by broadcasters and CATV systems were described in Fortnightly in the following terms:
“Broadcasters select the programs to be viewed; CATV systems simply carry, without editing, whatever programs they receive. Broadcasters procure programs and propagate them to the public; CATV systems receive programs that have been released to *410the public and carry them by private channels to additional viewers.” Id., at 400.
Even in exercising its limited freedom to choose among various broadcasting stations, a CATY operator simply cannot be viewed as “selecting,” “procuring,” or “propagating” broadcast signals as those terms were used in Fortnightly. When a local broadcasting station selects a program to be broadcast at a certain time, it is exercising a creative choice among the many possible programs available from the national network with which it is affiliated, from copyright holders of new or rerun motion pictures, or from its own facilities to generate and produce entirely original program material. The alternatives are myriad, and the creative possibilities limited only by scope of imagination and financial considerations. An operator of a CATY system, however, makes a choice as to which broadcast signals to rechannel to its subscribers, and its creative function is then extinguished. Thereafter it “simply carr [ies], without editing, whatever programs [it] receive [s].” Ibid. Moreover, a CATV system importing “distant” signals does not procure programs and propagate them to the public, since it is not engaged in converting the sights and sounds of an event or a program into electronic signals available to the public. The electronic signals it receives and rechannels have already been “released to the public” even though they may not be normally available to the specific segment of the public served by the CATV system.
Finally, it is contended that importation of “distant” signals should entail copyright infringement liability because of the deleterious impact of such retransmission upon the economics and market structure of copyright licensing. When a copyright holder first licenses a copyrighted program to be shown on broadcast television, he *411typically cannot expect to recoup his entire investment from a single broadcast. Rather, after a program has had a “first run” on the major broadcasting networks, it is often later syndicated to affiliates and independent stations for “second run” propagation to secondary markets. The copyright holders argue that if CATV systems are allowed to import programs and rechannel them into secondary markets they will dilute the profitability of later syndications, since viewer appeal, as measured by various rating systems, diminishes with each successive showing in a given market. We are told that in order to ensure “the general benefits derived by the public from the labors of authors,” Fox Film Corp. v. Doyal, 286 U. S. 123, 127, and “ 'the incentive to further efforts for the same important objects,’ ” id., at 127-128, citing Kendall v. Winsor, 21 How. 322, 328, current licensing relationships must be maintained.
In the television industry, however, the commercial relations between the copyright holders and the licensees on the one hand and the viewing public on the other are such that dilution or dislocation of markets does not have the direct economic or copyright significance that this argument ascribes to it. Unlike propagators of other copyrighted material, such as those who sell books, perform live dramatic productions, or project motion pictures to live audiences, holders of copyrights for television programs or their licensees are not paid directly by those who ultimately enjoy the publication of the material — that is, the television viewers — but by advertisers who use the drawing power of the copyrighted material to promote their goods and services. Such advertisers typically pay the broadcasters a fee for each transmission of an advertisement based on an estimate of the expected number and characteristics of the viewers who will watch the program. While, as members of the *412general public, the viewers indirectly pay for the privilege of viewing copyrighted material through increased prices for the goods and services of the advertisers, they are not involved in a direct economic relationship with the copyright holders or their licensees.13
By extending the range of viewability of a broadcast program, CATV systems thus do not interfere in any traditional sense with the copyright holders’ means of extracting recompense for their creativity or labor. When a broadcaster transmits a program under license from the copyright holder he has no control over the segment of the population which may view the program— the broadcaster cannot beam the program exclusively to the young or to the old, only to women or only to men— but rather he gets paid by advertisers on the basis of all viewers who watch the program. The use of CATV does not significantly alter this situation. Instead of basing advertising fees on the number of viewers within the range of direct transmission plus those who may receive “local signals” via a CATV system, broadcasters whose reception ranges have been extended by means of “distant” signal CATV rechanneling will merely have a different and larger viewer market.14 From the point of *413view of the broadcasters, such market extension may-mark a reallocation of the potential number of viewers each station may reach, a fact of no direct concern under the Copyright Act. From the point of view of the copyright holders, such market changes will mean that the compensation a broadcaster will be willing to pay for the use of copyrighted material will be calculated on the basis of the size of the direct broadcast market augmented by the size of the CATV market.15
*414These shifts in current business and commercial relationships, while of significance with respect to the organization and growth of the communications industry, simply cannot be controlled by means of litigation based on copyright legislation enacted more than half a century ago, when neither broadcast television nor CATV was yet conceived. Detailed regulation of these relationships, and any ultimate resolution of the many sensitive and important problems in this field, must be left to Congress.16
*415The judgment of the Court of Appeals is affirmed in part and reversed in part, and these cases are remanded to the District Court with directions to reinstate its judgment.
It is so ordered.
The exclusive rights of copyright owners are specified in § 1 of the Copyright Act:
“Any person entitled thereto, upon complying with the provisions of this title, shall have the exclusive right:
“(a) To print, reprint, publish, copy, and vend the copyrighted work;
“(b) To translate the copyrighted work into other languages or dialects, or make any other version thereof, if it be a literary work; to dramatize it if it be a nondramatic work; to convert it into a novel or other nondramatic work if it be a drama; to arrange or adapt it if it be a musical work; to complete, execute, and finish it if it be a model or design for a work of art;
“(c) To deliver, authorize the delivery of, read, or present the copyrighted work in public for profit if it be a lecture, sermon, address or similar production, or other nondramatic literary work; to make or procure the making of any transcription or record thereof by or from which, in whole or in part, it may in any manner or by any method be exhibited, delivered, presented, produced, or reproduced; and to play or perform it in public for profit, and to exhibit, represent, produce, or reproduce it in any manner or by any method whatsoever. The damages for the infringement by broadcast of any work referred to in this subsection shall not exceed the sum of $100 where the infringing broadcaster shows that he was not aware that he was infringing and that such infringement could not have been reasonably foreseen; and
“(d) To perform or represent the copyrighted work publicly if it be a drama or, if it be a dramatic work and not reproduced in copies for sale, to vend any manuscript or any record whatsoever thereof; to make or to procure the making of any transcription or record thereof by or from which, in whole or in part, it may in any manner or by any method be exhibited, performed, represented, produced, or reproduced; and to exhibit, perform, represent, produce, or reproduce it in any manner or by any method whatsoever; and
“(e) To perform the copyrighted work publicly for profit if it be a musical composition; and for the purpose of public performance for profit, and for the purposes set forth in subsection (a) hereof, to make any arrangement or setting of it or of the melody of it *398in any system of notation or any form of record in which the thought of an author may be recorded and from which it may be read or reproduced . . . .” 17 U. S. C. § 1.
Although the Copj'right Act does not contain an explicit definition of infringement, it is settled that unauthorized use of copyrighted material inconsistent with the “exclusive rights” enumerated in § 1, constitutes copyright infringement under federal law. See 1 M. Nimmer, Copyright § 100, p. 376 (1973). Use of copyrighted material not in conflict with a right secured by § 1, however, no matter how widespread, is not copyright infringement. “The fundamental [is] that 'use’ is not the same thing as 'infringement,' that use short of infringement is to be encouraged ....’’ B. Kaplan, An Unhurried View of Copyright 57 (1967).
It appears to be conceded that liability in this case depends entirely on whether the defendants did "perform” the copyrighted works. Teleprompter has not contended in this Court that, if it did "perform” the material, its performance was not “in public” within the meaning of § 1 (c) of the Act (nondramatic literary works) or "publicly” under § 1 (d) (dramatic works). Cf. Fortnightly Corp. v. United Artists Television, 392 U. S. 390, 395 n. 13.
The plaintiffs’ amended complaints also contained allegations of additional copyright infringements on various dates in 1969 and 1971.
The Court of Appeals in this ease described the differences between point-to-point microwave transmission and broadcasting in the following terms:
“A microwave link involves the transmission of signals through the air. However, microwave transmission in itself is not broadcasting. A broadcast signal, according to 47 U. S. C. § 153 (o), is transmitted by a broadcaster for '[reception] by the public.’ In the case- of microwave, the signal is focused and transmitted in a narrow beam aimed with precision at the - receiving points. Thus, microwave transmission is point-to-point communication. The receiving antenna must be in the path of the signal beam. If the transmission must cover a considerable distance, the microwave signal is transmitted to the first receiving point from which it is retransmitted to another receiving point, and this process is repeated until the signal reaches the point from which it is distributed by cable to subscribers.” 476 F. 2d 338, 343 n. 6.
The plaintiffs argued in the District Court and in the Court of Appeals that “the use of microwave, in and of itself, is sufficient to make a CATV system functionally equivalent to a broadcaster *400and thus subject to copyright liability . . . Id,., at 348-349. This contention was rejected by the Court of Appeals on the ground that microwave transmission “is merely an alternative, more economical in some circumstances, to cable in transmitting a broadcast signal from one point in a CATV sj'stem to another,” id., at 349, and the argument has not been renewed in this Court.
For general descriptions of CATV sj'stems and their operation, see United States v. Southwestern Cable Co., 392 U. S. 157; M. Seiden, An Economic Analysis of Community Antenna Television Systems and the Television Broadcasting Industry (1965); Note, Regulation of Community Antenna Television, 70 Col. L. Rev. 837 (1970); Note, The Wire Mire: The FCC and CATV, 79 Harv. L. Rev. 366 (1965).
In two of the cities involved in this suit signals not normally receivable by household sets because of distance or terrain could be received by rooftop antennae because of the use by the broadcasting stations of “translators,” under license from the Federal Communications Commission, which rebroadcast a specific station’s signals. See 476 F. 2d, at 344 and n. 7.
The Court of Appeals acknowledged that a determination of what is a “distant” signal was “difficult,” and “that a precise judicial definition of a distant signal is not possible.” 476 F. 2d, at 350. FCC *402regulations at one time provided that for regulatory purposes a distant signal was one “which is extended or received beyond the Grade B contour of that station.” 47 CFR § 74.1101 (i) (1971) (removed in 37 Fed. Reg. 3278 (1972)). A Grade B contour was defined as a line along which good reception maj’ be expected 90% of the time at 50% of the locations. United States v. Southwestern Cable Co., supra, at 163 n. 16. The Court of Appeals recognized that “this definition [is] unsuitable for copyright purposes because . . . any definition phrased in terms of what can be received in area homes using rooftop antennas would fly in the face of the mandate of Fortnightly.” 476 F. 2d, at 350. The court found instead that “it is easier to state what is not a distant signal than to state what is a distant signal. Accordingly, we have concluded that any signal capable of projecting, without relay or retransmittal, an acceptable image that a CATV system receives off-the-air during a substantial portion of the time by means of an antenna erected in or adjacent to the CATV community is not a distant signal.” Id., at 351 (footnote omitted).
Program origination initially consisted of simple arrangements on spare channels using automated cameras providing time, weather, news ticker, or stock ticker information, and aural systems with music or news announcements. The function has been expanded to include coverage of sports and other live events, news services, moving picture films, and specially created dramatic and nondramatic programs. See CATV-First Report and Order, 20 F. C. C. 2d 201; United States v. Midwest Video Corp., 406 U. S. 649.
The Court of Appeals limited its discussion of interconnection among CATV systems to two instances of live coverage of championship heavyweight boxing contests. While the respondents contend *405that additional examples of interconnection were presented in the trial testimony, they do not suggest that material copyrighted by anyone other than the CATV operators was carried by any such interconnection, and thus the exact number of such instances is of no significance.
While the technology apparently exists whereby a CATV system could retransmit to its subscribers broadcast programs taken off-the-air but substitute its own commercials for those appearing in the broadcast, none of the instances of claimed infringement involved such a process.
The FCC has consistently contended that it is without power to alter rights emanating from other sources, including the Copyright Act. In 1966 it indicated that its proposed rules regulating CATV *407operations would not “affect in any way the pending copyright suits, involving as they do matters entirely beyond [the FCC's] jurisdiction.” Second Report and Order, Community Antenna Television Systems, 2 F. C. C. 2d 725, 768. This position is consistent with the terms of the Communications Act of 1934, the source of the Commission’s regulatory power, which provides, in part:
“Nothing in this chapter contained shall in any .way abridge or alter the remedies now existing at common law or by statute, but the provisions of this chapter are in addition to such remedies.” 47 U. S. C. § 414.
Thus, it is highly unlikely that the “distant” signal definition adopted by the Commission or a differentiation of function based on such a definition was intended to or could have copyright significance. Indeed, as noted, the Court of Appeals in the present case found that the Commission’s definition of a “distant” signal was unsatisfactory for determining if a “performance” under the Copyright Act had occurred. See n. 7, supra.
For example, it was represented in a brief before this Court that the Farmington, New Mexico, CATV system imported signals from a Los Angeles station even though 113 other stations were closer or equidistant, including a number which, unlike the Los Angeles station, were in the same time zone as the Farmington community.
Some commentators have suggested that if CATV systems must pay license fees for the privilege of retransmitting copyrighted broadcast programs, the CATV subscribers will in effect be paying twice for the privilege of seeing such programs: first through increased prices for the goods and services of the advertisers who pay for the television broadcasts and a second time in the increased cost of the CATV service. Note, CATV and Copyright Liability: On .a Clear Day You Can See Forever, 52 Va. L. Rev. 1505, 1515 (1966) ; Note, CATV and Copyright Liability, 80 Harv. L. Rev. 1514, 1522-1523 (1967). See n. 15,infra.
Testimony and exhibits introduced in the District Court indicate that the major rating services cover in their compilations statistics concerning the entire number of viewers of a particular program, including those who receive the broadcast via “distant” transmission *413over CATV systems. The weight given such statistics by advertisers who bid for broadcast time and pay the fees which support the broadcasting industry was not, however, established. See n. 15, infra.
It is contended that copyright holders will necessarily suffer a net loss from the dissemination of their copyrighted material if license-free use of “distant” signal importation is permitted. It is said that importation of copyrighted material into a secondary market will result in a loss in the secondary market without increasing revenues from the extended primary market on a scale sufficient to compensate for that loss. The assumption is that local advertisers supporting “first run” programs will be unlikely to pay significantly higher fees on the basis of additional viewers in a “distant” market because such viewers will typically have no commercial interest in the goods and services sold by purely local advertisers. For discussion of the possible impact of CATV “distant” signal importation on advertiser markets for broadcast television, see 52 Va. L. Rev., at 1513-1516; 80 Harv. L. Rev., at 1522-1525. The Court of Appeals noted that “[n]o evidence was presented in the court below to show that regional or local advertisers would be willing to pay greater fees because the sponsored program will be exhibited in some distant market, or that national advertisers would pay more for the relatively minor increase in audience size that CATV carriage would yield for a network program,” and concluded that “[i]ndeed, economics and common sense would impel one to an opposite conclusion.” 476 F. 2d, at 342 n. 2. Thus, no specific findings of fact were made concerning the precise impact of “distant” signal retransmission on the value of program copyrights. But such a showing would be of very little relevance to the copyright question we decide here. At issue in this *414case is the limited question of whether CATV transmission of “distant” signals constitutes a “performance” under the Copyright Act. While securing compensation to the holders of copyrights was an essential purpose of that Act, freezing existing economic arrangements for doing so was not. It has been suggested that the best theoretical approach to the problem might be “[a] rule which called for compensation to copyright holders only for the actual advertising time 'wasted' on local advertisers unwilling to pay for the increase in audience size brought about by the cable transmission,” Note, 87 Harv. L. Rev. 665, 675 n. 32 (1974). But such a rule would entail extended factfinding and a legislative, rather than a judicial, judgment. In any event, a determination of the best alternative structure for providing compensation to copyright holders, or a prediction of the possible evolution in the relationship between advertising markets and the television medium, is beyond the competence of this Court.
The pre-Fortnightly history of efforts to update the Copyright Act to deal with technological developments such as CATV was reviewed in the Fortnightly opinion, 392 U. S., at 396 n. 17. At that time legislative action to revise the copyright laws so as to resolve copyright problems posed by CATV was of such apparent imminence that the Solicitor General initially suggested to this Court that it defer judicial resolution of the Fortnightly case in order to allow a speedy completion of pending legislative proceedings. Those legislative activities, however, did not bear fruit, apparent^ because of the diversity and delicacy of the interests affected by the CATV problem. See 117 Cong. Rec. 2001 (1971) (remarks of Sen. McClellan). Further attempts at revision in the 91st Congress, S. *415542, and the 92d Congress, S. 644, met with a similar lack of success. At present, Senate hearings in the Subcommittee on Patents, Trademarks and Copyrights have been held on a bill that would amend the Copyright Act, S. 1361, but the bill has not yet been reported out of that subcommittee. A companion bill has been introduced in the House of Representatives, H. R. 8186, and referred to Judiciary Committee No. 3, but no hearings have yet been scheduled.
