In August 1920, representatives from four states: Akron, Canton, Cleveland, and Dayton, held a meeting and formed the American Professional Football Conference (APFC) to improve footballing standards in the country. A month later, they formed the American Professional Football Association (APFA) and played a league with 14 teams. In 1922, they changed the name to the National Football League (NFL).
In 1960, a new professional league, the American Football League (AFL) started as a competition against the NFL. After six years, in 1966, the two leagues announced a merger that would take effect in 1970. During the four years between the announcement and the actual merger, the leagues started playing a Championship game which was called The Super Bowl. Since then, the two leagues have been recognized as two separate conferences within the same league, the NFL.
There are 32 teams in the NFL divided equally into two conferences: National Football Conference (NFC) and the American Football Conference (AFC). Each conference is further divided into 4 divisions: East, North, South, and West, with each division containing four teams.
