Football used to be two different leagues, the National Football League and the American Football league. The two leagues merged in 1970 to form the National Football League, consisting of two conferences: the American Football Conference (AFC) and the National Football Conference (NFC). Currently, each conference has 16 teams, divided into 4 divisions of 4 teams each. The winner of each division and the next top 2 teams, called Wild Cards, go to single elimination playoffs. The winner of each set of playoffs goes to the Super Bowl. This year, the San Francisco 49ers won the NFC championship and so they are going to the Super Bowl against the Kansas City Chiefs who are the winners of the AFC championship.
