The AFL–NFL merger of 1970 was the merger of the two major professional American football leagues in the United States at the time: the National Football League (NFL) and the American Football League (AFL). The merger paved the way for the combined league, which retained the "National Football League" name and logo, to become one of the most popular sports leagues in the United States.
The AFC West is a division of the National Football League's American Football Conference, currently comprising the Denver Broncos, San Diego Chargers, Kansas City Chiefs, and Oakland Raiders.
The division has sent teams to the Super Bowl fourteen times beginning with Super Bowl I vs. Green Bay. The Raiders entering 2012 lead in Super Bowl wins with a 3–2 record; the Broncos presently are 2–4 in Super Bowls; the Chiefs are 1–1 while the Chargers went winless in Super Bowl XXIX, their lone Super Bowl appearance.
