National Collegiate Athletic Association
The National Collegiate Athletic Association (NCAA) (pronounced "N-C-Double-A") is a nonprofit association of 1,281 institutions, conferences, organizations and individuals that organizes the athletic programs of many colleges and universities in the United States and Canada. It is headquartered in Indianapolis, Indiana.
In August 1973, the current three-division setup of Division I, Division II, and Division III was adopted by the NCAA membership in a special convention. Under NCAA rules, Division I and Division II schools can offer scholarships to athletes for playing a sport. Division III schools may not offer any athletic scholarships. Generally, larger schools compete in Division I and smaller schools in II and III. Division I football was further divided into I-A and I-AA in 1978. Subsequently the term "Division I-AAA" was briefly added to delineate Division I schools which do not field a football program at all, but that term is no longer officially used by the NCAA. In 2006, Divisions I-A and I-AA were respectively renamed the Football Bowl Subdivision (FBS) and Football Championship Subdivision (FCS).

The Bowl Championship Series (BCS), in American football, is a selection system that creates five bowl match-ups involving ten of the top ranked teams in the NCAA Division I Football Bowl Subdivision (FBS), including an opportunity for the top two to compete in the BCS National Championship Game.
The BCS relies on a combination of polls and computer selection methods to determine relative team rankings, and to narrow the field to two teams to play in the BCS National Championship Game held after the other college bowl games. The American Football Coaches Association is contractually bound to vote the winner of this game as the BCS National Champion and the contract signed by each conference requires them to recognize the winner of the BCS National Championship game as the official and only Champion. The BCS was created to end split championships and for the Champion to win the title on the field between the two teams selected by the BCS. Despite this objective on one occasion it failed to produce a consensus champion, as the 2003 NCAA Division I-A football season ended with a split title.
