History
The Bills began competitive play in 1960 as a charter member of the American Football League led by head coach Buster Ramsey and joined the NFL as part of the AFL–NFL merger in 1970.
Logos and uniforms
For their first two seasons, the Bills wore uniforms based on those of the Detroit Lions at the time. Ralph Wilson had been a minority owner of the Lions before founding the Bills, and the Bills' predecessors in the AAFC had also worn blue and silver uniforms.
Rivalries
The Bills have rivalries with their three AFC East opponents, and also have had historical rivalries with other teams such as the Baltimore/Indianapolis Colts (a former divisional rival), Kansas City Chiefs, Houston Oilers/Tennessee Titans, Jacksonville Jaguars, and Dallas Cowboys. They also play an annual preseason game against the Detroit Lions .
Notable players
The Buffalo Bills have retired three numbers in franchise history: No. 12 for Jim Kelly, No. 34 for Thurman Thomas and No. 78 for Bruce Smith. Despite the fact that the Bills have retired only three jersey numbers, the team has other numbers no longer issued to any player or in reduced circulation.
Radio and television
The Buffalo Bills Radio Network is flagshipped at WGR AM 550 in Buffalo, with sister station WWKB AM 1520 simulcasting all home games. John Murphy is the team's current play-by-play announcer; he was a color commentator alongside, and eventually succeeded, longtime voice Van Miller after Miller's retirement at the end of the 2003 NFL season.
Mascots, cheerleaders and marching band
The Bills' official mascot is Billy Buffalo, an eight-foot-tall, anthropomorphic blue American bison who wears the jersey "number" BB.
