What team is the only non-profit, community owned major league professional sports team in the U.S.?

The Green Bay Packers are the only non-profit, community owned major league professional sports team based in the United States. They play their home games at Lambeau Field in Green Bay, Wisconsin.

The Packers are the last vestige of "small town teams" common in the NFL during the 1920s and 1930s. Founded in 1919 by Earl "Curly" Lambeau and George Whitney Calhoun, the franchise traces its lineage to other semi-professional teams in Green Bay dating back to 1896. In 1919 and 1920, the Packers competed against other semi-pro clubs from around Wisconsin and the Midwest. They joined the American Professional Football Association (APFA), the forerunner of today's NFL, in 1921. Although Green Bay is by far the smallest professional sports market in North America, its local fan and media base extends 120 miles south into Milwaukee, Wisconsin where it played selected home games between 1933 and 1994.

The Packers are long-standing adversaries of the Chicago Bears, Minnesota Vikings and Detroit Lions, who together comprise the NFL's NFC North division. The Bears and Packers rivalry is one of the oldest in NFL history, dating back to 1921.
