The Packers were formed in 1919
and joined the NFL in 1921. No team in NFL history has
won more championships than the Packers which has earned Green
Bay the moniker, "Titletown USA." Over the years,
the Packers have twice strung together three straight league
crowns (1929-31, and 1965-67). In all, the franchise has
claimed a record 12 NFL championships including three Super
Bowl titles.
