the time that a particular episode aired. During the 1952–53 season, Cantor suffered a heart attack immediately after a Colgate Comedy Hour broadcast in September. Although he quickly recovered and returned in January 1953, he was reluctant to move on with the show. By the fourth season, the sponsor was providing $6,000,000, but the performers were finding difficulty in offering fresh material. Ratings hence began to decline. Cantor had become too ill to continue in the hosting role, and the travel was too stressful and painful for him. His final Colgate appearance was in May 1954. Vic Schoen was hired as the musical director in 1954. In 1954, Tony Martinez, later cast as the farmhand on The Real McCoys, made his television debut on The Colgate Comedy Hour. In June 1955, the show changed its name to the Colgate Variety Hour to reflect a move away from pure comedy. A number of the earlier hosts had left by the end of the 1953–54 season (with the exception of Martin & Lewis) as the show shifted toward mini-musicals, starring hosts such as Ethel Merman and Frank Sinatra, who paired together in truncated version of Cole Porter's "Anything Goes".

The final show, emceed by the series' last continuing host Robert Paige, aired as a Christmas special on December 25, 1955, with Fred Waring and his Pennsylvanians choral ensemble. The Colgate Comedy Hour was replaced on January 8, 1956 with the NBC Comedy Hour, hosted by Leo Durocher for the first three shows. After Durocher, the regular hosts changed, and after 18 broadcasts, the final show aired in June. Regular supporting casts always co-starred in each of the episodes. Jonathan Winters was featured on the show. On May 11, 1967, NBC broadcast a special Colgate Comedy Hour revival (pre-empting The Dean Martin Show, which Colgate sponsored at the time), with guests Nanette Fabray, Kaye Ballard, Edie Adams, Carl Reiner and Mel Brooks (performing one of their "2000
