Since its opening in 1957, fans attending games have seen many expansions. By 1961, City Stadiums' capacity was increased to over 38,000. Two years later the capacity was once again increased to over 42,000. In 1965, City Stadium was renamed Lambeau Field, after the death of the Packers founder, E.L. Lambeau. During the same year the capacity was increased to 50,852. Once this addition was completed, Lambeau Field got its basic shape. The entire field was enclosed by seats. In 1985, 72 luxury suites were added along with additional seating areas, bringing the capacity to over 56,000. Again in 1990, 80 more luxury suites were added along with over 1,900 club seats along the top rim of the stadium. In 1993, the first video/scoreboard was installed above the south endzone; and in 1995, 90 more luxury suites were added.

Instead of opting to build a new stadium, the Packers announced in January of 2000, that they would extensively renovate and expand Lambeau Field. Between 2001 and the start of the 2003 season, Lambeau Field underwent many improvements to make it more fan and player friendly. The main concourse was expanded, a new upper concourse was added with ramps and elevators, and more restrooms were added. In addition, nearly 12,000 seats were added along the top of the stadium. This included club seats and new luxury suites. An atrium, known as "Titletown" was built as part of the new facade of Lambeau Field. Here fans find a Packers Hall of Fame and a team store. A new Packers locker room, football operations facility, and administrative offices were also constructed. All the renovations to Lambeau Field were completed in time for the start of the 2003 season. Throughout these additions to Lambeau Field, the stadium has become one of the NFL’s recognizable stadiums. Today, Lambeau Field has a capacity of over 72,000. One tier of bleacher seats circle the entire field. The luxury boxes, club seats, and press boxes, are atop the stadium rim. Over its 40 years of existence, Lambeau Field has been the site of many historical moments including the first NFL Championship game in Green Bay in 1961and the "Ice Bowl" in December of 1967, when the temperature was 13 degrees below zero.
