The SEC was the first NCAA conference in any division to hold a football championship game that was exempt from NCAA limits on regular-season contests. Such a game was made possible by two separate developments. The first came in 1987, when the NCAA membership approved a proposal sponsored by the Division II Pennsylvania State Athletic Conference and Central Intercollegiate Athletic Association that allowed any conference with at least 12 football members to split into divisions and stage a championship game between the divisional winners. The SEC took advantage of this rule by adding the University of Arkansas and the University of South Carolina in 1992, bringing the conference membership to 12, and splitting into two football divisions. The format has since been adopted by other conferences to decide their football champion (the first being the Big 12 in 1996).
