The history of the Green Bay Packers is rich with on-field accomplishments and a special bond with the community that has supported the organization throughout its 91-year history. As the legend of the Green Bay Packers has grown through time, so has the Packers' responsibility to the community like no other team in the NFL.
Green Bay Packers, Inc., has been a publicly owned, nonprofit corporation since Aug. 18, 1923, when original articles of incorporation were filed with Wisconsin’s secretary of state.
A total of 4,750,937 shares is owned by 112,158 stockholders —none of whom receives any dividend on the initial investment. 
One of the more remarkable business stories in American history, the team is kept viable by its shareholders — its unselfish fans. Even more incredible, the Packers have survived during the current era, permeated by free agency and the NFL salary cap. And, thanks in large part to Brown County’s passage of the 2000 Lambeau Field referendum, the club will remain solvent and highly competitive well into the future due to its redeveloped stadium.
To protect against someone taking control of the team, the articles of incorporation prohibit any person from owning more than 200,000 shares. Keeping the organization loyalty to the fans and community that supports them.
In 1960, the league wrote a rule into its own constitution prohibiting additional nonprofit, publicly owned teams.
