The Philadelphia 76ers are an American professional basketball team based in the Philadelphia metropolitan area. They compete in the National Basketball Association (NBA) as a member of the Atlantic Division of the Eastern Conference. The team is the oldest franchise in the NBA and is named for the 1776 signing of the Declaration of Independence in Philadelphia. The 76ers have won three NBA championships (1955, 1967, and 1983) and have advanced to the NBA finals on nine occasions. The team plays its home games at the Wells Fargo Center located in the South Philadelphia Sports Complex. The shorter name "Sixers" is often used for marketing purposes and has been officially interchangeable with "76ers" for most of the last 60 years. The team has had periods of both success and struggle throughout its history, including a team-record seven-year playoff drought from the 1991-92 season to the 1997-98 season, and a recent period of predominately average play in the 2010s. However, the team has also had notable players such as Wilt Chamberlain, Hal Greer, Billy Cunningham, and Allen Iverson, who led the 76ers to the 2001 NBA finals. The team is currently at a critical crossroads in the offseason.
