Its base was the RKO General-owned radio stations in New York, Los Angeles, San Francisco and other large markets.
RKO initially purchased downlink satellite dishes for its affiliates, creating the nation's first satellite-delivered commercial radio network.
Both networks offered sportscasts, music, public affairs programming and closed-circuit affiliate feeds of news and sports correspondent reports.
The network aired the last interview with John Lennon, recorded at The Dakota just hours before his death on December 8, 1980, by Dave Sholin, a San Francisco DJ, and scriptwriter/newscaster Laurie Kaye, with radio producer Ron Hummel, who put together many music specials for RKO.
The RKO Radio Networks were headquartered at 1440 Broadway in New York City, also the home of co-owned WOR (AM).
