The Rose Bowl was the only major college bowl game in 1930. By 1940, there were five major college bowl games: the Rose Bowl, the Sugar Bowl (1935), the Cotton Bowl Classic (1937), the Orange Bowl (1935), and the Sun Bowl (1935). By 1950, the number had increased to eight games. This figure of eight bowl games persisted through 1960, but by 1970 the number had increased again, to 11 games. The number continued to increase, to 15 games in 1980, to 19 games in 1990, 25 games in 2000, 35 games in 2010, and 41 games by 2015 (40 games plus two teams playing a second game to determine the National Champion). Up until around the 1950s, the small number of games were played solely on New Year's Day, with the only major exception being the holiday occurring on a Sunday. For the 2016–17 bowl season, the 41 games require a little over three weeks, starting December 17 and ending on January 9. While bowl games were originally exclusive to warm cities thought of as winter vacation destinations, indoor stadiums allow games to be played in colder climates.
