The AFL-NFL merger occurred in 1970, combining the two rival professional football leagues in the United States: the American Football League (AFL) and the National Football League (NFL). This merger aimed to unify the leagues, enhance competition, and create a more structured playoff system, culminating in the annual Super Bowl championship game. As a result of the merger, the NFL expanded to include AFL teams, leading to the formation of two conferences: the AFC and the NFC. The merger also established a common draft system and improved television contracts, significantly increasing the popularity and financial success of professional football in America.
