RKO Radio Network

The RKO Radio Networks, a subsidiary of RKO General, were the first commercial radio networks to distribute programming entirely by satellite. When it began operations on October 1, 1979, the initial RKO network was the first new full-service American radio network in 40 years. Satellite distribution allowed high-fidelity (15 kHz) stereo programming to its affiliates. 
News and programming.
The newscasts, aimed at a young adult audience, had a conversational, high-energy style developed by co-founders Vice President and News Director Dave Cooke, and Vice President of Programming Jo Interrante. 
RKO was popular from the start, signing up hundreds of affiliates coast to coast. 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. 
The original network, which fed newscasts at :50 repeated at :00, became known as "RKO 1" when "RKO 2" debuted on September 1, 1981. "RKO 2" fed newscasts at :20 repeated at :30 and was aimed at an older audience. Both networks offered sportscasts, music, public affairs programming and closed-circuit affiliate feeds of news and sports correspondent reports and news-maker actualities.
The networks were home to three groundbreaking long-form programs. "NightTime America with Bob Dearborn" was the first live, daily, satellite-delivered music show in radio history. Dearborn produced and hosted the five-hour adult contemporary show from January 9, 1981, until 1984. January 9, 1981, was also the premier of "America Overnight", a six-hour interview and call-in show hosted by Eric Tracey in Los Angeles and Ed Busch from Dallas. It was the first national talk show delivered by satellite. It also marked the first time a network offered simultaneous overnight programs. Dick Bartley created, produced and hosted the first live national oldies radio show, "Solid Gold Saturday Night".
Headquarters.
The RKO Radio Networks were headquartered at 1440 Broadway in New York City, also the home of co-owned WOR (AM). The offices were the former headquarters of the Mutual Broadcasting System when RKO General owned Mutual. RKO also staffed news bureaus in Washington, D.C., and London.
Notable events.
Last John Lennon interview.
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.
Billing scandal and sale.
After advertising billing scandals involving RKO's television stations and later the radio networks came to light, the RKO Radio Networks were sold in 1985 to the United Stations Radio Networks. Dick Clark Productions, owner of United Stations, sold the RKO Radio Network entity to Tom Ficara in 1990. United Stations was merged with Transtar Radio Networks to form Unistar Radio Networks in 1987. Unistar was absorbed by Westwood One in 1994 and its affiliates were switched to the Mutual Broadcasting System.
