The Adventures of Ozzie and Harriet premiered on ABC-TV on October 10, 1952
and due to declining ratings, the show was canceled with the last episode airing 
on September 3, 1966. The Adventures of Ozzie and Harriet ran for a total of 
fourteen seasons, and for almost four de cades, held the record as the longest  
running television sitcom, live or animated, until that record was broken by The
Simpsons in 2004. It still holds the record for the longest running live-action
sitcom in television history.
