During the eight years of President Ronald Reagan's administration, deregulation of broadcasting was pursued at least as vigorously as other attempts of the "Reagan Revolution" to lessen the impact and influence of the federal government. The Federal Communication Commission's (FCC) "one-to-a-market" rule (which limits licenses to one broadcast facility in any given market) was one of the broadcast ownership rules that was rendered far less important by the exceptions granted by the Reagan appointees' influence. The purpose of the rule, insuring a "plurality of voices" in the marketplace through diversity of ownership, was a worthy and appropriate goal of regulation. However, the actions of the FCC in granting an increasing number of exceptions have not helped attain that goal. (Twenty-six references are attached.) (Author/RAE)
