The Buffalo Bills are a professional American football team based in the Buffalo metropolitan area. They compete in the National Football League (NFL) as a member club of the league's American Football Conference (AFC) East division. The team plays its home games at Highmark Stadium in Orchard Park, New York. Founded in 1960 as a charter member of the American Football League (AFL), they joined the NFL in 1970 following the AFL–NFL merger. The Bills' name is derived from an All-America Football Conference (AAFC) franchise from Buffalo that was in turn named after western frontiersman Buffalo Bill. Drawing much of its fanbase from Western New York,[6] the Bills are the only NFL team that plays home games in that state.
