It is the purpose of the First Amendment to preserve an uninhibited marketplace 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. It is the right of the public to receive suitable access to social, political, aesthetic, moral and other ideas and experiences which is crucial here. That right may not constitutionally be abridged either by Congress or by the FCC.

McCarthy abridged that right by giving Tucker the monopoly on the videos.
