The history of the Federal Communications Commission's content regulation of broadcasting is a history of policymaking in a vacuum. A review of the literature reveals that no one has yet attempted to show whether the Fairness Doctrine results in poorer or better broadcast journalism.

After viewing broadcasting content regulation from these perspectives, one fact is highlighted: no one has done a good job of justifying content regulation. It is clear from a review of content regulation that public policy must be based on evidence to be supportable. (Ninety-five footnotes are appended.) (MM)
