In 1975, Gunsmoke was cancelled after 20 years on the air (the longest running prime-time drama until Law and Order tied it). This was in spite of still high ratings, and the cancellation came as a surprise to the people involved as they didn't know CBS was even thinking about it. To quote James Arness, who played sheriff Matt Dillion, "We didn't do a final, wrap-up show. We finished the 20th year, we all expected to go on for another season, or two or three. The (network) never told anybody they were thinking of canceling." In it's place, CBS put the Mary Tyler Moore spin-offs Rhoda and Phyllis.
Gunsmoke avoided cancellation once before when in 1967, it was removed from the schedule due to fan pressure and the wife of the president of CBS urging him not to cancel it. Gilligan's Island was cancelled instead.
So what if Gunsmoke avoided being cancelled, and ran for that extra 1, 2, or 3 seasons mentioned by Arness, if not more?
