It rotates between 4 or now maybe 5 different bowl games. Fiesta, Sugar, Orange, Rose and I believe a new historic bowl was added this last year.

The 2007 national championship game (actually to be played in 2008) will be in the Louisiana Superdome (site of the Sugar Bowl). The date of the game is 1 week after the BCS game played at the same site (though, for some reason, this year's game will be on Jan 7, just 6 days after the Sugar Bowl.)
The National Football League was founded in 1920 under the name American Professional Football Association. The name was changed to National Football League in 1922.
