 Given the interest of the impromptu " championship game " , and the desire of the league to create a more equitable means of determining a champion , the league divided into two conferences beginning in 1933 . The winners of each conference ( the first place teams in the conferences ) will play in the NFL Championship Game after the season . There was no tie @-@ breaker system in place ; any ties in the final standings of either conference resulted in a playoff game being played in 1941 , 1943 , 1947 , two games in 1950 , and one each in 1952 , 1957 , 1958 , and 1965 . Since the venue and date of the championship game were often not known until the last game of the season had been played , these playoff games sometimes resulted in delaying the end of the season by one week .

 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 . An earlier league , the All @-@ America Football Conference , was in play from 1946 to 1949 . After the league dissolved , two AAFC teams , the Cleveland Browns and the San Francisco 49ers , became members of the NFL ; another member , the Baltimore Colts joined the league , but folded after just a year in the NFL .

 American football leagues exist throughout the world , but the game has yet to achieve the international success and popularity of baseball and basketball . NFL Europa , the developmental league of the NFL , operated from 1991 to 1992 and then from 1995 to 2007 . At the time of its closure , NFL Europa had five teams based in Germany and one in the Netherlands .

 A new professional league , the fourth American Football League ( AFL ) , began play in 1960 . The upstart AFL began to challenge the established NFL in popularity , gaining lucrative television contracts and engaging in a bidding war with the NFL for free agents and draft picks . The two leagues announced a merger on June 8 , 1966 , to take full effect in 1970 . In the meantime , the leagues would hold a common draft and championship game . The game , the Super Bowl , was held four times before the merger , with the NFL winning Super Bowl I and Super Bowl II , and the AFL winning Super Bowl III and Super Bowl IV . After the league merged , it was reorganized into two conferences : the National Football Conference ( NFC ) , consisting of most of the pre @-@ merger NFL teams , and the American Football Conference ( AFC ) , consisting of all of the AFL teams as well as three pre @-@ merger NFL teams .

 The National Football League ( NFL ) playoffs are a single @-@ elimination tournament held after the end of the regular season to determine the NFL champion . Six teams from each of the league 's two conferences qualify for the playoffs based on regular season records , and a tie @-@ breaking procedure exists in the case of equal records . The tournament ends with the Super Bowl , the league 's championship game , which matches the two conference champions .
