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.
