Based on a Richard Hooker novel of the same name, MASH was released in 1970 as a full-length feature film by 20th Century Fox before experiencing widespread success as a groundbreaking television sitcom in the Fall of 1972. The show's brilliant integration of drama and comedy made it one of the most celebrated shows in TV history, culminating in an eleven year prime time series stint. The 1983 series finale of MASH made history as the program with the single largest audience in television history, beating out several SuperBowls and the fabled "Who Shot J.R." episode of Dallas. With the proliferation of new television mediums, it's a record likely to never be broken

The sitcom is set in South Korea during American involvement in the Korea War (with M*A*S*H standing for "Mobile Army Surgical Hospital"). Buffered from the front lines by a mountain range and a minefield, the men and women of MASH were tasked with patching up wounded American soldiers. Unique to its genre, the cast of MASH was unusually large. Surgeons Dr. Benjamin Pierce (Alan Alda) and Dr. "Trapper" John McIntyre (Wayne Rogers) play the roles of excellent doctors who enjoy women and booze, while Dr. Frank Burns (Larry Linville) and Nurse Practitioner Margaret "Hot Lips" Houlihan (Loretta Swit) play foil to the two men's shenanigans (due to a contract dispute, Rogers' character was later replaced by Dr. B.J. Hunnicutt - played by Mike Farrell). The character of Frank Burns was also later replaced by Dr. Charles Emerson Winchester (David Ogden Stiers)

Corporal Max Klinger (Jamie Farr) provides comic relief with his early attempts to procure a discharge by dressing in women's clothing, and Father Francis Mulcahy (William Christopher) adds flavor to a diverse cast of characters. Also rounding out the cast are Lt. Col. Henry Blake (McLean Stevenson), Corporal Walter "Radar" O'Reilly (Gary Burghoff), and Col. Sherman Potter (Harry Morgan)

The MASH (Season 4) DVD offers a number of hilarious episodes including the series premiere "Welcome to Korea" in which Trapper John McIntyre receives orders to ship home and is replaced by Dr. B.J. Hunnicutt (Mike Farrell). Meanwhile, Pierce butts heads with temporary commanding officer Frank Burns as he attempts to say goodbye to Trapper John before he leaves (Pierce was on leave when the orders came in) Other notable episodes from Season 4 include "The Late Captain Pierce" in which Pierce's father is mistakenly notified of his son's death, and "The Gun" in which a wounded colonel's collectable gun turns up missing (prompting Pierce and B.J. to hunt down the culprit)
