 Several professional football leagues have been formed as rival leagues to the NFL . The most successful rival league was the American Football League ( AFL ) , which existed from 1960 to 1969 . The AFL became a significant rival in 1964 before signing a five @-@ year , US $ 36 million television deal with NBC . AFL teams began to sign NFL players to contracts , and the league 's popularity grew to challenge that of the NFL . The two leagues merged in the 1970 season , and all AFL teams joined the NFL .
