The Buffalo Bills are a professional American football team based in Buffalo, New York. They are members of the National Football League (NFL) as part of the American Football Conference (AFC) in the AFC East division. They play their home games in the suburb of Orchard Park at Ralph Wilson Stadium (since 1973), and since 2008 have played one home game per season in Toronto.
The Bills began competitive play in 1960 as a charter member of the American Football League (AFL). The franchise won two consecutive AFL titles in 1964 and 1965, but the club has not won a league championship since the AFL-NFL merger in 1970. Buffalo is also the only team to win four consecutive AFC Championships -- and the only team ever to play in four consecutive Super Bowl games.
The Bills were named as the result of the winning entry in a local contest, which named the team after the AAFC Buffalo Bills, a previous football franchise from the All-America Football Conference (AAFC) that merged with the Cleveland Browns and San Francisco 49ers in 1950. That team, in turn, was named after William Frederick "Buffalo Bill" Cody.
