The Ed Sullivan Show is an American television variety show that ran on CBS from June 20, 1948, to March 28, 1971, and was hosted by New York entertainment columnist Ed Sullivan. It was replaced in September 1971 by the CBS Sunday Night Movie. From 1948 until its cancellation in 1971, the show ran on CBS every Sunday night from 8–9 p.m. Eastern Time, and it is one of the few entertainment shows to have run in the same weekly time slot on the same network for more than two decades (during its first season, it ran from 9 to 10 p.m. ET). Virtually every type of entertainment appeared on the show; classical musicians, opera singers, popular recording artists, songwriters, comedians, ballet dancers, dramatic actors performing monologues from plays, and circus acts were regularly featured. The format was essentially the same as vaudeville and, although vaudeville had undergone a slow demise for a generation, Sullivan presented many ex-vaudevillians on his show. The Ed Sullivan Show was originally broadcast via live television from CBS-TV studio 51, the Maxine Elliott Theatre, at Broadway and 39th St. before moving to its permanent home at CBS-TV Studio 50 in New York City (1697 Broadway, at 53rd Street), which was renamed the Ed Sullivan Theater on the occasion of the program's 20th anniversary in June 1968. The last original Sullivan show telecast (#1068) was on March 28, 1971, with guests Melanie, Joanna Simon, Danny Davis and the Nashville Brass and Sandler and Young. It was one of many older shows with followings in undesirable key demographics that were purged from the network lineups that summer leading into the Prime Time Access Rule taking effect that fall. Repeats were scheduled through June 6, 1971.
