TheNFLHistorian

The NFL was formed on August 20, 1920 as the American Professional Football Conference; the league changed its name to the American Professional Football Association (APFA) on September 17, 1920 and changed their name to the National Football League on June 24, 1922 after spending the 1920 and 1921 season as the APFA. In 1966, the NFL agreed to merge effective 1970 with the rival American Football League (AFL); the first Super Bowl was held at the end of that same season in January 1967. Today, the NFL has the highest average attendance (67,591) of any professional sports league in the world and is the most popular sports league in the United States. The Super Bowl is among the biggest club sporting events in the world and individual Super Bowl games account for many of the most-watched programs in American history.
