The All-America Football Conference (AAFC) was a major professional American football league that challenged the established National Football League (NFL) from 1946 to 1949. One of the NFL's most formidable challengers, the AAFC attracted many of the nation's best players, and introduced many lasting innovations to the game. However, the AAFC was ultimately unable to sustain itself in competition with the NFL. After it folded, three of its teams were admitted to the NFL: the San Francisco 49ers, the Cleveland Browns and the original Baltimore Colts.
Below is a list of professional football Championship Games in the United States, involving:
The 1990 NFL season was the 71st regular season of the National Football League (NFL). To increase revenue, the league, for the first time since 1966, reinstated bye weeks, so that all NFL teams would play their 16-game schedule over a 17-week period. Furthermore, the playoff format was expanded from 10 teams to 12 teams by adding another wild card from each conference, thus adding two more contests to the postseason schedule; this format was modified with realignment in 2002 before the playoffs expanded to 14 teams in 2020.
