MASH was a unique mixture of tragedy and comedy, and while it could heartbreakingly sad, it still had its share of hilarious episodes too. This medical sitcom debuted in 1972, and while it was always intended to have an anti-war tone, it was much more of a comedy initially. The death of Henry Blake in MASH season 3 stunned audiences after it aired, and underlined the fact its main characters faced life-or-death situations daily. From there, the series evolved into one of the first real dramedies on television.
