The District Court concluded that a less restrictive alternative is available: § 504, with adequate publicity. No one disputes that § 504, which requires cable operators to block undesired channels at individual households upon request, is narrowly tailored to the Government’s goal of supporting parents who want those channels blocked. The question is whether § 504 can be effective.
When a plausible, less restrictive alternative is offered to a content-based speech restriction, it is the Government’s obligation to prove that the alternative will be ineffective to achieve its goals. The Government has not met that burden here. In support of its position, the Government cites empirical evidence showing that § 504, as promulgated and implemented before trial, generated few requests for household-by-household blocking. Between March 1996 and May 1997, while the Government was enjoined from enforcing § 505, § 504 remained in operation. A survey of cable operators determined that fewer than 0.5% of cable subscribers requested full blocking during that time. . . .
The District Court was correct to direct its attention to the import of this tepid response. Placing the burden of proof upon the Government, the District Court examined whether § 504 was capable of serving as an effective, less restrictive means of reaching the Government’s goals. It concluded that § 504, if publicized in an adequate manner, could be.
