The U.S. network that originally aired the M*A*S*H television series was CBS.
The series premiered on September 17, 1972, and remained on CBS through its final broadcast on February 28, 1983. It was developed by Larry Gelbart and produced by 20th Century-Fox Television, adapting the 1970 film and Richard Hooker’s 1968 novel.
CBS was the original broadcaster, not Fox, ABC, or NBC. The program became one of the most successful shows in American television history, combining comedy, medical drama, and war-related storytelling across 11 seasons and 256 episodes.
Its finale, “Goodbye, Farewell and Amen,” aired on CBS in 1983 and drew about 106 million viewers in the United States. That record helped cement the network’s association with one of television’s most enduring series.
