The Federal Communications Commission (FCC) has for many years imposed on broadcasters a "fairness doctrine," requiring that public issues be presented by broadcasters and that each side of those issues be given fair coverage. In No. 2, the FCC declared that petitioner Red Lion Broadcasting Co. had failed to meet its obligation under the fairness doctrine when it carried a program which constituted a personal attack on one Cook, and ordered it to send a transcript of the broadcast to Cook and provide reply time, whether or not Cook would pay for it. The Court of Appeals upheld the FCC's position. After the commencement of the Red Lion litigation, the FCC began a rulemaking proceeding to make the personal attack aspect of the fairness doctrine more precise and more readily enforceable, and to specify its rules relating to political editorials. The rules, as adopted and amended, were held unconstitutional by the Court of Appeals in RTNDA (No. 717) as abridging the freedoms of speech and press.
Moved to action by a widely felt need to sponsor independent sources of broadcast programming as an alternative to commercial broadcasting, Congress set out in 1967 to support and promote the development of noncommercial, educational broadcasting stations. A keystone of Congress' program was the Public Broadcasting Act of 1967, Pub. L. 90-129, 81 Stat. 365, 47 U. S. C. § 390 et seq., which established the Corporation for Public Broadcasting, a nonprofit corporation authorized to disburse federal funds to noncommercial television and radio stations in support of station operations and educational programming. Section 399 of that Act, as amended by the Public Broadcasting Amendments Act of 1981, Pub. L. 97-35, 95 Stat. 730, forbids any "noncommercial educational broadcasting station which receives a grant from the Corporation" to "engage in editorializing." 47 U. S. C. § 399. In this case, we are called upon to decide whether Congress, by imposing that restriction, has passed a "law . . . abridging the freedom of speech, or of the press" in violation of the First Amendment of the Constitution.
