"may require adjustments in marketing strategy, but it did not establish even a likelihood of harm.” Id., at 469. “Television production by plaintiffs today is more profitable than it has ever been, and, in five weeks of trial, there was no concrete evidence to suggest that the Betamax will change the studios’ financial picture.” Ibid. The District Court’s conclusions are buttressed by the fact that to the extent time-shifting expands public access to freely broadcast television programs, it yields societal benefits. Earlier this year, in Community Television of Southern California v. Gottfried, — U.S. — -, — - - — -, n. 12, 103 S.Ct. 885, 891-892, 74 L.Ed.2d 705 (1983), we acknowledged the public interest in making television broadcasting more available. Concededly, that interest is not unlimited. But it supports an interpretation of the concept of “fair use” that requires the copyright holder to demonstrate some likelihood of harm before he may condemn a private act of time-shifting as a violation of federal law. When these factors are all weighed in the “equitable rule of reason” balance, we must conclude that this record amply supports the District Court’s conclusion that home time - shifting is fair use. In light of the findings of the District Court regarding the state of the empirical data, it is clear that the Court of Appeals erred in holding that the statute as presently written bars such conduct."
