The show's final episode which aired on February 28, 1983 was one of the most watched shows in TV history. It was viewed by 125 million people. There have been several spin-off series of "M*A*S*H". The first was "AfterMASH", which was about a Veteran's Hospital soon after the war was over. It was about Colonel Potter (Harry Morgan), who got a job there, Maxwell Klinger (Jamie Farr), who became his assistant, and Father Mulcahy (William Christopher), who came there as a patient who abused alcohol after he lost his hearing in the TV series. All three of them were major characters on the original series. The second spin-off was "W*A*L*T*E*R*", which was about Walter "Radar" O'Reilly (Gary Burghoff). It was an unsold pilot that was shown as a special television program. The most successful "M*A*S*H" spin-off was "Trapper John, M.D.", a spin-off of the movie. It starred Trapper John McIntyre (Pernell Roberts), but never talks about anything from the movie. It lasted 151 episodes across seven seasons.
