[395 U.S. 382-383] The objectives of 315 themselves could readily be circumvented but for the complementary fairness doctrine ratified by 315. The section applies only to campaign appearances by candidates, and not by family, friends, campaign managers, or other supporters. Without the fairness doctrine, then, a licensee could ban all campaign appearances by candidates themselves from the air 13 and [395 U.S. 367, 383] proceed to deliver over his station entirely to the supporters of one slate of candidates, to the exclusion of all others. In this way the broadcaster could have a far greater impact on the favored candidacy than he could by simply allowing a spot appearance by the candidate himself. It is the fairness doctrine as an aspect of the obligation to operate in the public interest, rather than 315, which prohibits the broadcaster from taking such a step.

[395 U.S. 383] The legislative history reinforces this view of the effect of the 1959 amendment. Even before the language relevant here was added, the Senate report on amending 315 noted that "broadcast frequencies are limited and, therefore, they have been necessarily considered a public trust. Every licensee who is fortunate in obtaining a license is mandated to operate in the public interest and has assumed the obligation of presenting important public questions fairly and without bias." S. Rep. No. 562, 86th Cong., 1st Sess., 8-9 (1959). See also, specifically adverting to Federal Communications Commission doctrine, id., at 13.

[395 U.S. 383-384] Rather than leave this approval solely in the legislative history, Senator Proxmire suggested an amendment to make it part of the Act. 105 Cong. Rec. 14457. This amendment, which Senator Pastore, a manager of the bill and a ranking member of the Senate Committee, considered "rather surplusage," 105 Cong. Rec. 14462, constituted a positive statement of doctrine 14 and was altered [395 U.S. 367, 384] to the present merely approving language in the conference committee. In explaining the language to the Senate after the committee changes, Senator Pastore said: "We insisted that that provision remain in the bill, to be a continuing reminder and admonition to the Federal Communications Commission and to the broadcasters alike, that we were not abandoning the philosophy that gave birth to section 315, in giving the people the right to have a full and complete disclosure of conflicting views on news of interest to the people of the country." 105 Cong. Rec. 17830. Senator Scott, another Senate manager, added that: "It is intended to encompass all legitimate areas of public importance which are controversial," not just politics. 105 Cong. Rec. 17831.

[395 U.S. 389-390] This is not to say that the First Amendment is irrelevant to public broadcasting. On the contrary, it has a major role to play as the Congress itself recognized in 326, which forbids FCC interference with "the right [395 U.S. 367, 390] of free speech by means of radio communication." Because of the scarcity of radio frequencies, the Government is permitted to put restraints on licensees in favor of others whose views should be expressed on this unique medium. But the people as a whole retain their interest in free speech by radio and their collective right to have the medium function consistently with the ends and purposes of the First Amendment. It is the right of the viewers and listeners, not the right of the broadcasters, which is paramount. See FCC v. Sanders Bros. Radio Station, 309 U.S. 470, 475 (1940); FCC v. Allentown Broadcasting Corp., 349 U.S. 358, 361 -362 (1955); 2 Z. Chafee, Government and Mass Communications 546 (1947).

[395 U.S. 390 ] It is the purpose of the First Amendment to preserve an uninhibited market-place of ideas in which truth will ultimately prevail, rather than to countenance monopolization of that market, whether it be by the Government itself or a private licensee. Associated Press v. United States, 326 U.S. 1, 20 (1945); New York Times Co. v. Sullivan, 376 U.S. 254, 270 (1964); Abrams v. United States, 250 U.S. 616, 630 (1919) (Holmes, J., dissenting). "[S]peech concerning public affairs is more than self-expression; it is the essence of self-government." Garrison v. Louisiana, 379 U.S. 64, 74 -75 (1964). See Brennan, The Supreme Court and the Meiklejohn Interpretation of the First Amendment, 79 Harv. L. Rev. 1 (1965). It is the right of the public to receive suitable access to social, political, esthetic, moral, and other ideas and experiences which is crucial here. That right may not constitutionally be abridged either by Congress or by the FCC.

[395 U.S. 394-395] In FRC v. Nelson Bros. Bond & Mortgage Co., 289 U.S. 266, 279 (1933), the Court noted that in "view of the limited number of available broadcasting frequencies, the Congress has authorized allocation and licenses." In determining how best to allocate frequencies, the Federal Radio Commission considered the needs of competing communities and the programs offered by competing stations to meet those needs; moreover, if needs or programs shifted, the Commission could alter its allocations to reflect those shifts. Id., at 285. In the same vein, in FCC v. Pottsville Broadcasting Co., 309 U.S. 134, 137 -138 (1940), the Court noted that [395 U.S. 367, 395] the statutory standard was a supple instrument to effect congressional desires "to maintain . . . a grip on the dynamic aspects of radio transmission" and to allay fears that "in the absence of governmental control the public interest might be subordinated to monopolistic domination in the broadcasting field."
