The Big Ten Conference is the oldest Division I collegiate athletic conference in the United States. Founded as the Intercollegiate Conference of Faculty Representatives in 1896, it predates the founding of its regulating organization, the NCAA. It is based in the Chicago area in Rosemont, Illinois. For many decades the conference consisted of 10 prominent universities, which accounts for its name. As of 2014, it consists of 14 member institutions and 2 affiliate institutions, with 4 new member institutions scheduled to join in 2024. The conference competes in the NCAA Division I and its football teams compete in the Football Bowl Subdivision (FBS), formerly known as Division I-A, the highest level of NCAA competition in that sport.

NCAA Division I (D-I) is the highest level of intercollegiate athletics sanctioned by the National Collegiate Athletic Association (NCAA) in the United States, which accepts players globally. D-I schools include the major collegiate athletic powers, with large budgets, more elaborate and nicer facilities and a few more athletic scholarships than Divisions II and III as well as many smaller schools committed to the highest level of intercollegiate competition.
