The United States Congress created the Federal
Communications Commission. In addition to regulating landline
interstate telephone business, they also began managing the radio
spectrum. It decided who would get what frequencies. It gave priority
to emergency services, government agencies, utility companies,
and services it thought helped the most people. Radio users like
a taxi service or a tow truck dispatch company required little
spectrum to conduct their business. Radio telephone used large
frequency allocations to serve a few people. The FCC designated
no radio-telephone channels until after World War II.
