NBC Red Network

The National Broadcasting Company's NBC Radio Network was an American commercial radio network which was in continuous operation from 1926 through 1999. Along with the NBC Blue Network, it was one of the first two nationwide networks established in the United States. Its major competitors were the Columbia Broadcasting System (CBS), founded in 1927, and the Mutual Broadcasting System, founded in 1934. In 1942, NBC was required to divest one of its national networks. As such, it sold NBC Blue, which was soon renamed the American Broadcasting Company (ABC). After this separation, the Red Network continued as the NBC Radio Network.
