On February 28, 1983, the celebrated sitcom M*A*S*H bows out
after 11 seasons, airing a special two-and-a-half hour episode
watched by 77 percent of the television viewing audience. It was
the largest percentage ever to watch a single TV show up to that
time.

Set near Seoul, Korea, behind the American front lines during
the Korean War, M*A*S*H was based on the 1968 novel by Richard
Hooker and the 1970 film produced by 20th Century Fox and
directed by Robert Altman. Its title came from the initials for the
Mobile Army Surgical Hospital.
