When does M*A*S*H* return?

M*A*S*H (an acronym for Mobile Army Surgical Hospital) 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, which, in turn, was based on Richard Hooker's 1968 novel MASH: A Novel About Three Army Doctors. The ensemble cast originally featured Alan Alda and Wayne Rogers as surgeons Benjamin "Hawkeye" Pierce and "Trapper" John McIntyre.
The series is usually categorized as a situation comedy, though it has also been described as a "dark comedy" or a "dramedy" because of the often dramatic subject matter. The show is an ensemble piece revolving around key personnel in a U.S. Army Mobile Army Surgical Hospital (MASH) in the Korean War (1950–53)
