The success of "The Mary Tyler Moore Show", "All in the Family", and newer, more urban variety shows such as "The Carol Burnett Show" in 1967 and "The Flip Wilson Show" in 1970 (on arch-rival NBC), allowed cancellations of most of the "undesired shows" at the end of 1971, despite their high ratings and popularity. Both "Green Acres" and "The Beverly Hillbillies" had dropped from the Nielsen top 30 by the 1970–71 season, yet both shows continued to win their respective time slots and had loyal followings, warranting renewal for another season. Other shows still pulling in even higher ratings when canceled included "Mayberry R.F.D.", which finished the season at number 15, "Hee Haw" at number 16, and "The Jim Nabors Hour" at number 29.
