The NFL, or National Football League, is a professional American football league consisting of 32 teams. It is divided into two conferences: the AFC (American Football Conference) and the NFC (National Football Conference). The league was founded in 1920 and has grown to become one of the most popular sports organizations in the United States, culminating in the annual championship game known as the Super Bowl. Each NFL season typically runs from September to February, featuring a regular season followed by playoffs. Teams compete for a chance to win the Lombardi Trophy, awarded to the Super Bowl champion. The NFL also has a significant cultural impact, with millions of fans engaging in games, fantasy leagues, and related events.
