Held: Aereo performs petitioners’ works publicly within the meaning of the Transmit Clause. Pp. 4–18.
(a) Aereo “perform[s].” It does not merely supply equipment that allows others to do so. Pp. 4–10.
(1) One of Congress’ primary purposes in amending the Copyright Act in 1976 was to overturn this Court’s holdings that the activities of community antenna television (CATV) providers fell outside the Act’s scope. In Fortnightly Corp. v. United Artists Television, Inc., 392 U. S. 390, the Court determined that a CATV provider was more like a viewer than a broadcaster, because its system “no more than enhances the viewer’s capacity to receive the broadcaster’s signals [by] provid[ing] a well-located antenna with an efficient connection to the viewer’s television set.” Id., at 399. Therefore, the Court concluded, a CATV provider did not perform publicly. The Court reached the same determination in respect to a CATV provider that retransmitted signals from hundreds of miles away in Teleprompter Corp. v. Columbia Broadcasting System, Inc., 415 U. S. 394. “The reception and rechanneling of [broadcast television signals] for simultaneous viewing is essentially a viewer function, irrespective of the distance between the broadcasting station and the ultimate viewer,” the Court said. Id., at 408. Pp. 4–7.
(2) In 1976, Congress amended the Copyright Act in large part to reject the Fortnightly and Teleprompter holdings. The Act now clarifies that to “perform” an audiovisual work means “to show its images in any sequence or to make the sounds accompanying it audible.” §101. Thus, both the broadcaster and the viewer “perform,” because they both show a television program’s images and make audible the program’s sounds. Congress also enacted the Transmit Clause, which specifies that an entity performs when it “transmit[s] . . . a performance . . . to the public.” Ibid. The Clause makes clear that an entity that acts like a CATV system itself performs, even when it simply enhances viewers’ ability to receive broadcast television signals. Congress further created a complex licensing scheme that sets out the conditions, including the payment of compulsory fees, under which cable systems may retransmit broadcasts to the public. §111. Congress made all three of these changes to bring cable system activities within the Copyright Act’s scope. Pp. 7–8.
(3) Because Aereo’s activities are substantially similar to those of the CATV companies that Congress amended the Act to reach, Aereo is not simply an equipment provider. Aereo sells a service that allows subscribers to watch television programs, many of which are copyrighted, virtually as they are being broadcast. Aereo uses its own equipment, housed in a centralized warehouse, outside of its users’ homes. By means of its technology, Aereo’s system “receive[s] programs that have been released to the public and carr[ies] them by private channels to additional viewers.” Fortnightly, supra, at 400. This Court recognizes one particular difference between Aereo’s system and the cable systems at issue in Fortnightly and Teleprompter: The systems in those cases transmitted constantly, whereas Aereo’s system remains inert until a subscriber indicates that she wants to watch a program. In other cases involving different kinds of service or technology providers, a user’s involvement in the operation of the provider’s equipment and selection of the content transmitted may well bear on whether the provider performs within the meaning of the Act. But given Aereo’s overwhelming likeness to the cable companies targeted by the 1976 amendments, this sole technological difference between Aereo and traditional cable companies does not make a critical difference here. Pp. 8–10.
(b) Aereo also performs petitioners’ works “publicly.” Under the Clause, an entity performs a work publicly when it “transmit[s] . . . a performance . . . of the work . . . to the public.” §101. What performance, if any, does Aereo transmit? Petitioners say Aereo transmits a prior performance of their works, whereas Aereo says the performance it transmits is the new performance created by its act of transmitting. This Court assumes arguendo that Aereo is correct and thus assumes, for present purposes, that to transmit a performance of an audiovisual work means to communicate contemporaneously visible images and contemporaneously audible sounds of the work. Under the Court’s assumed definition, Aereo transmits a performance whenever its subscribers watch a program. What about the Clause’s further requirement that Aereo transmit a performance “to the public”? Aereo claims that because it transmits from user-specific copies, using individually-assigned antennas, and because each transmission is available to only one subscriber, it does not transmit a performance “to the public.” Viewed in terms of Congress’ regulatory objectives, these behind-the-scenes technological differences do not distinguish Aereo’s system from cable systems, which do perform publicly. Congress would as much have intended to protect a copyright holder from the unlicensed activities of Aereo as from those of cable companies. The text of the Clause effectuates Congress’ intent. Under the Clause, an entity may transmit a performance through multiple transmissions, where the performance is of the same work. Thus when an entity communicates the same contemporaneously perceptible images and sounds to multiple people, it “transmit[s] . . . a performance” to them, irrespective of the number of discrete communications it makes and irrespective of whether it transmits using a single copy of the work or, as Aereo does, using an individual personal copy for each viewer. Moreover, the subscribers to whom Aereo transmits constitute “the public” under the Act. This is because Aereo communicates the same contemporaneously perceptible images and sounds to a large number of people who are unrelated and unknown to each other. In addition, neither the record nor Aereo suggests that Aereo’s subscribers receive performances in their capacities as owners or possessors of the underlying works. This is relevant because when an entity performs to a set of people, whether they constitute “the public” often depends upon their relationship to the underlying work. Finally, the statute makes clear that the fact that Aereo’s subscribers may receive the same programs at different times and locations is of no consequence. Aereo transmits a performance of petitioners’ works “to the public.” Pp. 11– 15.
(c) Given the limited nature of this holding, the Court does not be- lieve its decision will discourage the emergence or use of different kinds of technologies. Pp. 15–17.
