The National Broadcasting Company's NBC Red Network (after 1942 the NBC Radio Network) is a former American commercial radio
network, which along with the NBC Blue Network was founded in 1926. These were the first two nationwide networks established in the United States. Their major
competitors were the Columbia Broadcasting System (CBS), founded in 1927, and the Mutual Broadcasting System, founded in 1934. In 1943, NBC was required to
divest one of its national networks, so 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. In 1987 NBC sold its remaining radio network operations to Westwood One, which continued using NBC identification for some
of its programming until 2014. Beginning in 2016, NBC Radio News has been distributed in conjunction with iHeartMedia.
