The Green Bay Packers are a professional American football team based in Green Bay, Wisconsin. They were founded in 1919 by Earl "Curly" Lambeau and George Whitney Calhoun. The team's name comes from their original sponsor, the Indian Packing Company, a meat packing company where Lambeau worked. The company provided funds for uniforms and equipment on the condition the team be named the "Packers." The team played locally in Wisconsin and the upper peninsula of Michigan before joining the National Football League (then the American Professional Football Association) in 1921. The Packers are well known for being the only non-profit, community-owned major league professional sports team in the U.S. and they have a rich history with many championships to their name.
