The term "bowl" originated from the Rose Bowl stadium, site of the first post-season college football games. The Rose Bowl Stadium, in turn, takes its name and bowl-shaped design from the Yale Bowl, the prototype of many football stadiums in the United States. The term has since become almost synonymous with any major American football event, generally collegiate football with some significant exceptions. Two examples are the Egg Bowl, the name of the annual matchup between the Mississippi State Bulldogs and the Ole Miss Rebels, and the Iron Bowl, a nickname given to the annual game between the Alabama Crimson Tide and the Auburn Tigers. In professional football, the names of the National Football League (NFL)'s Super Bowl and Pro Bowl are references to college football bowl games.
