The Red Skelton Show was on the air for 20 years, the longest-running primetime network comedy variety series on television. It was a top 10 series for nine years--an accomplishment surpassed only by Gunsmoke and Home Improvement. The series has a few unimpressive achievements too, such as becoming the first top 10 series to be cancelled by a network. Here is the history of The Red Skelton Show, beginning with its debut in 1951, one of the top five that year. The show then declined in popularity, moved from CBS to NBC in 1953, slowly rose back to the top. In its glory days of the 1960s it became an hour long show and finished at number two in two different years. The cancellation of the show by CBS in 1970 despite its place in the top 10 was a surprise; the last season back with NBC was a failure. Appendices list cast and crew credits and special guests by season, and offer information on the post-Red Skelton lives of many of the principal players.
