From 1968, the game usually featured the champion of the former Big Eight Conference (whose members formed the basis of the current Big 12 Conference). Since 1998, however, with the creation of the Bowl Championship Series system, team selection for the Orange Bowl is now tied into the other three BCS Bowls. From 1998-2005, the game hosted the champion of either the ACC or Big East conferences, unless they were invited to the National Championship game. Starting with the 2006 season, the Orange Bowl will be exclusively tied with the ACC and will use the brand Home of the ACC Champion. As one of the Bowl Championship Series (BCS) bowl games (the others being the Sugar, Fiesta, and Rose Bowls), the Orange Bowl had hosted the national championship game once every four years under the BCS system (as it did on January 4, 2005).
