Champion History of Superbowl?

The SuperBowl is an annual American football game that determines the champion of the National Football League NFL. The contest is held in an American city that is chosen three to four years beforehand, usually in warm-weather or domed sites. The winner of the American Football Conference AFC Championship Game faces the winner of the National Football Conference NFC Championship Game in the culmination of the NFL playoffs. Before the 1970 merger between the American Football League AFL and the National Football League (NFL), the two leagues met in a World Championship Game and Super Bowl III in 1969 was the first Super Bowl that carried the "Super Bowl" moniker at the time of the game. The NFC leads in Super Bowl wins with 22, while the AFC has won 21. The NFL and AFL each won two World Championships.
