Debuted on Christmas Eve, 1948 on NBC. Switched to CBS in October 1950 but would revert back to NBC in September 1955 until its final weekly broadcast on 12 June 1963. From time to time the show would return still bearing the title "The Perry Como Show", but, like the "Hallmark Hall of Fame", not as a weekly series. Perry remained quite popular and would continue doing irregular specials through 1966 along with his ubiquitous Christmas shows.
Shown as a 15 minute show until June 1949 on NBC. Expanded to a 30 minute format on NBC after its return from summer hiatus but reverted to a 15 minute show when it moved over to CBS in October 1950 until June, 1955. After another summer hiatus and a move back to NBC, it expanded to a full hour until it ended its weekly run in June 1963. Kraft Foods assumed sponsorship from Chesterfield Cigarettes in 1961.
