The Packers were formed and joined the NFL in 1921, 1 year after the league was founded. They are currently the 2nd oldest team in the NFL, 2 years younger than the Chicago Bears. Therefore the Packers are a very historic franchise, and they have more NFL titles than anyone else: 9 NFL Championships, and an additional 3 modern era Super Bowl victories for a grand total of 12. The Chicago Bears have the 2nd most with 9. Those facts are the basis for the distinguished rivalry that exists between the Packers and Bears. Together they own the longest rivalry in the NFL, having played each other over 170 times.
Green Bay Packers fans are referred to as "Cheeseheads" because of the state of Wisconsin's large cheese production. While it is often debated which NFL team has the biggest/best fan base, it is hard to deny the Packers are at the top since every Packers home game has been sold out since 1960, and the waiting list for season tickets has over 70,000 people on it.
