The historic timing of bowl games, around the new year, is the result of two factors—warm climate and ease of travel. The original bowls began in warm climates such as Southern California, Louisiana, Florida, and Texas as a way to promote the area for tourism and business. Since commercial air travel was either non-existent or very limited, the games were scheduled well after the end of the regular season to allow fans to travel to the game site. While modern travel is more convenient, all but 5 of 41 bowl games (as of 2016-17) are still located in cities below approximately 36° N.
