M*A*S*H is an American war comedy drama television series that aired on CBS from September 17, 1972, to February 28, 1983. It was developed by Larry Gelbart as the first original spin-off series adapted from the 1970 feature film M*A*S*H, which, in turn, was based on Richard Hooker's 1968 novel MASH: A Novel About Three Army Doctors. The series, which was produced with 20th Century Fox Television for CBS, follows a team of doctors and support staff stationed at the "4077th Mobile Army Surgical Hospital" in Uijeongbu, South Korea, during the Korean War (1950–53).
