M*A*S*H is an American television series developed by Larry Gelbart, adapted from the 1970 feature film MASH (which was itself based on the 1968 novel MASH: A Novel About Three Army Doctors, by Richard Hooker). The series is a medical drama/black comedy that was produced in association with 20th Century Fox Television for CBS. It follows a team of doctors and support staff stationed at the 4077th Mobile Army Surgical Hospital in Uijeongbu, South Korea, during the Korean War. M*A*S*H's title sequence featured an instrumental version of the song "Suicide Is Painless", which also appears in 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 on September 17, 1972, and ended February 28, 1983, with the finale becoming the most-watched television episode in U.S. television history, with about 106 million viewers. The show is still broadcast in syndication on various television stations. The series, which covered a three-year military conflict, spanned 251 episodes and lasted eleven seasons.
Many of the stories in the early seasons are based on real-life tales told by real MASH surgeons who were interviewed by the production team. Like the movie, the series was as much an allegory about the Vietnam War (still in progress when the show began) as it was about the Korean War.
