RKO General Inc. was an American broadcasting company that, from 1952 through 1991, served as the main holding company for the noncore businesses of the General Tire and Rubber Company and later on GenCorp. The concern was based around the consolidation of its parent company's broadcasting interests, which dated to 1943 and were brought together under the General Teleradio umbrella in 1952. The company was renamed RKO Teleradio Pictures following its 1955 purchase of the RKO Pictures film studio, and then RKO General in 1959 after dissolving the motion picture division. Headquartered in New York City, the company operated six television stations and more than a dozen major radio stations around North America between 1959 and 1991.
