From Wikipedia:
Perry Como made the move to television when NBC initially televised the Chesterfield Supper Club radio program on December 24, 1948. During the 1949-50 season, it became a weekly half-hour offering on Sunday nights, directly opposite Ed Sullivan's Toast of the Town. In 1950, Perry moved to CBS and the show's title was changed to The Perry Como Show, again sponsored by Liggett & Myers' Chesterfield cigarettes. Como hosted this informal 15 minute musical variety series on Monday, Wednesday and Friday, immediately following the CBS Television News (later known as Douglas Edwards with the News). The Faye Emerson Show was initially broadcast in the same time slot on Tuesday and Thursday.
Como's 15-minute television show, which was also simulcast on radio via the Mutual Broadcasting System for several years, continued through the early 1950s until he moved back to NBC in the fall of 1955 on Saturdays with a weekly hour long variety show featuring additional musical and production numbers, comedy sketches and guest stars. On September 15, 1956, the season premiere of The Perry Como Show was broadcast from NBC's new color television studios at the New York Ziegfeld Theatre, making it one of the first weekly color TV shows. In 1959, Como moved to Wednesday nights, hosting the Perry Como's Kraft Music Hall for the next eight years, the last four seasons (1963-67) as monthly specials alternating with Kraft Suspense Theatre, The Andy Williams Show, and finally The Road West.
