The Steelers, whose history may be traced to a regional pro team that was established in the early 1920s, joined the NFL as the Pittsburgh Pirates on July 8, 1933. The team was owned by Art Rooney and took its original name from the baseball team of the same name, as was common practice for NFL teams at the time. To distinguish them from the baseball team, local media took to calling the football team the Rooneymen, an unofficial nickname that persisted for decades after the team had adopted its current nickname. The ownership of the Steelers has remained within the Rooney family since the organization's founding. Art Rooney's son, Dan Rooney, owned the team from 1988 until his death in 2017. Much control of the franchise has been given to Dan Rooney's son, Art Rooney II.
