The Pittsburgh Steelers are a professional American football team based in Pittsburgh, Pennsylvania. They were established on July 8, 1933, and have been playing in the National Football League (NFL) since then. The team has won six Super Bowl titles and eight American Football Conference (AFC) championships, making them one of the NFL's most successful franchises. The Steelers were founded by Pittsburgh resident Art Rooney, who used winnings from a wager on a horse race to establish the franchise. The team was originally called the Pittsburgh Pirates, but the name was changed to the Steelers in 1940 to better reflect the city's dominant steel industry. The team's colors are black and gold, and their mascot is Steely McBeam. The Steelers are currently owned by the Rooney family, and the team is headquartered in the UPMC Rooney Sports Complex in Pittsburgh.
