You should cheer for the Green Bay Packers. They are the most unique sports team in all of North America.
The Green Bay Packers were founded on August 11, 1919 by Curly Lambeau and George Whitney Calhoun. Lambeau solicited funds for uniforms from his employer, the Indian Packing Company. He was given $500 for uniforms and equipment, on the condition that the team be named for its sponsor. Today, "Green Bay Packers" is the oldest team name still in use in the NFL.
The Packers are now the only publicly owned company in American professional sports. Typically, a team is owned by one person, partnership, or corporate entity; thus, a "team owner." It has been speculated that this is one of the reasons the Green Bay Packers have never been moved from the city of Green Bay, a city of only 102,313 people in the 2000 census. (By comparison, the typical NFL football city's population is in the millions.)
Basically the Packers are the NFL equivalent of Ngamer, except the Pack is literally owned by just over 100,000 everyday people who live in the Green Bay area, whereas Ngamer gets owned everyday by any one of around 100,000 people.
