Final episode of M*A*S*H airs

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, an isolated compound that received wounded soldiers and was staffed by the show’s cast of doctors and nurses.

At the heart of M*A*S*H were the surgeons Dr. Benjamin Franklin “Hawkeye” Pierce (played by Alan Alda) and Dr. “Trapper” John McIntyre (Wayne Rogers); these roles were played in the Altman movie by Donald Sutherland and Elliott Gould, respectively. Hawkeye and Trapper’s foils on the TV show were Dr. Frank Burns (Larry Linville) and Senior Nurse Major Margaret “Hot Lips” Houlihan (Loretta Swit), who disapproved of the surgeons’ boozing, womanizing and disregard for military authority. Other key characters in the series were the bumbling camp commander, Lt. Col. Henry Blake (McLean Stevenson) and his clerk and right-hand man, Corporal Walter “Radar” O’Reilly (Gary Burghoff).

M*A*S*H premiered on the CBS television network in September 1972. Under threat of cancellation during its first season because of low ratings, the show turned things around the following year, landing in the top 10 in the ratings and never dropping out of the top 20 for the rest of its run. While the show began as a thinly veiled critique of the Vietnam War, its focus switched to more character-driven plotlines after that war’s anti-climactic end, allowing the series to continue to hold the public’s attention as it developed. In the middle of the show’s tenure, Alda began to take more and more creative control, co-writing 13 episodes and directing more than 30, including the series finale. Alda became the first person ever to win Emmy Awards for acting, directing and writing for the same show.

Elements such as long-range and tracking camera shots as well as sophisticated editing techniques distinguished M*A*S*H from more traditional TV sitcoms. From the beginning, the influence of Altman’s movie was evident in the cinematic nature of the show’s camera work. In addition, each half-hour episode of M*A*S*H contained a signature mixture of dramatic and comedic plot lines, and its success marked the rise of a new genre of TV show dubbed “dramedy.”

After earning consistently high ratings throughout its 11-year run, M*A*S*H enjoyed enduring popularity in the following decades, as it became one of the world’s most syndicated shows. It also spawned an unsuccessful spin-off, AfterMASH, which CBS aired from 1983 to 1985.
