As early as the 1930s, debate raged in Washington, D.C., and in the U.S. broadcasting industry over whether continuation of the clear-channel system was justifiable. The licensees of clear-channel stations argued that, without their special status, many rural areas would receive no radio service at all. Rural broadcasters pointed out that most of the clear-channel stations were licensed to serve large cities on the two coasts, which made little sense for a service that was meant to provide radio to the vast rural areas in the middle of the country. The clear-channel licensees requested that the power limit on the "I-A" channels in the U.S., set at 50 kW by the FCC, be lifted entirely. They pointed to successful experiments made by WLW in Cincinnati before the war, and in later years successful implementation by state broadcasters in Europe and the Middle East, as evidence that this would work and improve the service received by most Americans. Other broadcasters, particularly in the western states, argued to the contrary; that if the special status of the clear-channel stations was eliminated, "they" would be able to build facilities to provide local service to those rural "dark areas".
