On June 27, 1945, the FCC allocated 88-108 MHz for FM radio broadcasting – spectrum that it occupies to this day. In 1940 the Commission had allocated 42 to 50 MHz for FM radio, but made the move citing interference from atmospheric propagation anomalies. The change was controversial, with critics claiming it was intended to protect AM radio’s dominance. FM stations broadcast in both bands until January 8, 1949.
