Note: Cleveland Rams were in AFL 1936 before moving over to the NFL in 1937. Cleveland Browms & San Francisco 49’ers were in AAFC (All-America Football Conference 1946-1949) before moving over to NFL in 1950. Baltimore Colts were in AAFC (1947-1949), before moving over to NFL in 1950, but folded in 1951, and were replaced by Dallas Texans (1952), who also folded and the were also replaced by a new team called the Baltimore Colts. The NFL terms each of these teams (Baltimore Colts 1947-1951, Dallas Texans 1952 & Baltimore Colts 1953 onwards) as separate teams.
Note 2: The AFL (American Football League) of 1960-1969 was so successful it merged with the NFL in 1970, and played the Super Bowl between the two Leagues since 1966. All of the teams added in 1960 (bar Dallas Cowboys & Minnesota Vikings) were originally mermbers of the AFL.
