M*A*S*H* 4077th Vintage T-Shirt. M*A*S*H aired weekly in its original CBS run, with most episodes being a half-hour in length. The series is usually categorized as a situation comedy, though it is sometimes also described as a "dark comedy" or a "dramedy" because of the dramatic subject material often presented. Mash ran in our homes from 1972-1983. The show was an ensemble piece revolving around key personnel in a United States Army Mobile Army Surgical Hospital (MASH; the asterisks in the name are meaningless, a contrivance introduced in the novel) in the Korean War (1950–53). The 4077th MASH was just one of several surgical units in Korea. As the show developed, the writing took on more of a moralistic tone. In America, the series was shown complete with laugh track - but in the UK, it aired on BBC 2, and the laughter track was removed - the BBC insisted on all comedy programmes having a laughter track - but removed it from MASH. One episode was accidentally broadcast with the laugh track left in - the announcer apologized for "the technical problems we had".
