M*A*S*H is an American television series developed by Larry Gelbart, adapted from the 1970 feature film MASH. The series was produced in association with 20th Century Fox Television for CBS, which follows a team of doctors and support staff stationed at the "4077th Mobile Army Surgical Hospital" in Uijeongbu, South Korea during the Korean War. The show's title sequence features an instrumental version of "Suicide Is Painless", the theme song from the original film. The show was created after an attempt to film the original book's sequel, M*A*S*H Goes to Maine, failed. It is the most well known version of the M*A*S*H works.
The series premiered in the U.S. on September 17, 1972, and ended February 28, 1983, with the finale, "Goodbye, Farewell and Amen", becoming the most watched television episode in U.S. television history at the time, with a record-breaking 125 million viewers, according to the New York Times. It had struggled in its first season and was at risk of being cancelled. Season two of M*A*S*H placed it in a better time slot; the show became one of the top ten programs of the year and stayed in the top twenty programs for the rest of its eleven-season run. It is still broadcast in syndication on various television stations. The series, which depicted a three-year military conflict, spanned 256 episodes and lasted eleven seasons.
