As one of the oldest franchises in National Football League history, the Pittsburgh Steelers have made the playoffs 27 times as of 2014. The Steelers were founded in 1933, and the Arizona Cardinals, Chicago Bears, Green Bay Packers and New York GiantsÂ are the only teams that have played in the NFL longer.
Until the beginning of the Super Bowl era in 1967, the Steelers only made the playoffs once in 1947. However, they lost their only playoff game that season. Since the merger of the American Football League and the NFL in 1970, the Steelers have been one of the league's dominant teams. They have won the Super Bowl six times and lost twice.
