The Korean War show that lasted three times as long as the Korean War, taking off from the revolutionary 1970 Robert Altman comedy, as the doctors and nurses of the 4077th Mobile Army Surgical Hospital wait for the next chopper with the next crop of wounded grunts requiring “meatball surgery.” M*A*S*H began as a gritty comedy, with Alan Alda’s Hawkeye and the rest of the staff trying to keep their sense of humor alive amid the daily carnage with booze, sex and hijinks. It evolved into a solemn (if sometimes preachy) meditation on the futility of war. The finale was seen by more than 120 million and remains one of the most-watched TV events of all time.
Among the 15 TV shows considered “greater” than M*A*S*H are The West Wing, Game of Thrones, Freaks and Geeks, All in the Family, The Twilight Zone, and The Simpsons. For the record, here are the five greatest TV shows of all time according to Rolling Stone: Seinfeld, Mad Men, Breaking Bad, The Wire, and The Sopranos.
Lists like these are always subjective and tend to be skewed toward more recent TV shows. Back in 2013, TV Guide published its own list of the 60 Best Series of All Time and M*A*S*H ranked eighth.
