The highest level of professional American football in the United States is the National Football League (Nfl). The National Football League was formed by eleven teams in 1920 as the American Professional Football Association, with the league changing its name to the national Football League (Nfl) in 1922.
The Nfl currently consists of thirty-two teams from the United States.
The league is divided into two conferences: the american Football Conference and National Football Conference, and each conference has four teams each, for a total of 16 teams in each conference.
The Nfl is the most attended domestic sports league in the world by average attendance per game, with 66,960 fans per game in the season of 2010-2011.
The Nfl is an unincorporated association and a fedral nonprofit designation comprising its 32 teams.
The National Football League was the idea of the American-Indian Olympic legendary Jim Thrope, player-coach of the Canton Bulldogs, and Leo Lyons, owner of the Rochester Jeffersons in 1917.
On the twentieth of August in 1920, at a Hupmobile dealership in Canton, Ohio, the league was formalized, as the American Professional Football Conference, consisting only of the Ohio League teams.
A month later, the league was renamed the American Professional Football Association, in which the eleven founding teams struck an agreement over player poaching and the declaration of an end-of-season champion.
In 1958 , when that season’s Nfl championship game become known as “The Greatest Game Ever Played”, the Nfl was on its way to become one of the most popular sports leagues in the United States.
The Nfl solidified its dominance as America’s top spectator sport and its important role in American culture in the 1970s and 1980s.
