the four American college football games that would make up the Bowl Championship Series, the former unofficial national championship of the Division I Football Bowl Subdivision (formerly Division I-A). The game was played at Sun Devil Stadium in Tempe, Arizona through 2006 before moving to University of Phoenix Stadium in Glendale, Arizona in 2007. Following the 2006 season, Tostitos was the title sponsor for the BCS National Championship Game, a new game matching the number one and two teams in the final BCS standings. The title sponsor for the championship game rotated depending upon which site is hosting the 1 vs. 2 matchup. On June 9, 2014, Frito-Lay withdrew their sponsorship of the Fiesta Bowl citing the higher costs of sponsoring the event through the new College Football Playoff system.
