The Buffalo Bills were a charter member of the American Football Association, joining the NFL when the two leagues merged. They are the only team in the league to have won four consecutive AFC Championships and are also the only ones to move onto four consecutive Super Bowls, losing each.
Although one of three teams based in New York, the Bills are the only team that actually plays their home games in the state, with both the Jets and the Giants playing their home games in New Jersey. The Bills are also the only team that plays home games in Canada. One home game each year is held in Toronto as a result of a five year deal called the “Bills Toronto Series.”
