ABC News provides news and features content for select radio stations owned by Citadel Broadcasting, which purchased the ABC Radio properties in 2007 (however relaunched in 2014). In the 1930s, radio in the United States was dominated by three companies: the Columbia Broadcasting System (CBS), the Mutual Broadcasting System, and the National Broadcasting Company (NBC). The last was owned by electronics manufacturer Radio Corporation of America (RCA), which owned two radio networks that each ran different varieties of programming, NBC Blue and NBC Red. The NBC Blue Network was created in 1927 for the primary purpose of testing
NBC Sarnoff. After losing on final appeal before the U.S. Supreme Court in May 1943, RCA sold Blue Network Company, Inc., for $8 million to the American Broadcasting System, a recently founded company owned by Life Savers magnate Edward J. Noble. After the sale was completed on October 12, 1943, Noble acquired the rights to the Blue Network name, leases on landlines, the New York studios, two-and-a-half radio stations (WJZ in Newark/New York City; KGO in San Francisco and WENR in Chicago, which shared a frequency with Prairie Farmer station WLS); contracts with actors; and agreements with around 60 affiliates.
