Non-rural-themed shows canceled by CBS included sitcoms "Family Affair" and "Hogan's Heroes" in 1971, with the long-running "My Three Sons" ending in 1972. Variety shows that had been around since the late 1940s and early 1950s, such as "The Jackie Gleason Show" and "The Ed Sullivan Show", were canceled in 1970 and 1971, respectively; likewise, "The Original Amateur Hour" (a stalwart of network television since its debut, and before that on radio since 1934) ended on its own accord in 1970 due to the show's aging demographics. "The Red Skelton Show" was canceled by CBS at the end of the 1969–70 season, and was picked up by NBC (the series' original network) for one more season. NBC would also revert Skelton's show to its original half-hour format in place of its more familiar hour-long format on CBS. By the end of 1972, Lucille Ball remained the only long-time star from television's golden era to still have her own show. Ball's show, "Here's Lucy", still rated in the Nielsen top ten and would continue to pull in high ratings until its end in 1974.
