Conference USA, officially abbreviated C-USA, is a group of college sports teams that play each other on the NCAA Division I level. It was formed in 1995 when the Great Midwest Conference and Metro Conference merged, and has added several members since then. Most of the new members have come from either the Western Athletic Conference or the Sun Belt Conference. From 2005 to 2014, it also lost many members, mostly to the original Big East Conference and its football-playing offshoot, the American Athletic Conference.
