About American Football Conference (AFC)
The American Football Conference (AFC) is one of the two conferences of the National Football League (NFL). This conference and its counterpart, the National Football Conference (NFC), currently contain 16 teams each, making up the 32 teams of the NFL.
The American Football Conference originated as the American Football League (AFL), which joined with the NFL in the AFL–NFL merger of 1970. As such most of its teams originally played in the AFL, while three others were NFL teams that were added to the AFC to equalize the number of franchises, and another three are more recent expansion teams.
