Bateman was responsible for the building of 36 new buildings for the university both on and off campus, including the expansion of the Harold B. Lee Library. He was also one of several key college leaders who brought about the creation of the Mountain West Conference, which BYU's athletics program joined — BYU previously participated in the Western Athletic Conference. A BYU satellite TV network also opened in 2000 under his leadership. Bateman was also president during the September 11th attacks in 2001. The planes crashed on a Tuesday, hours before the weekly devotional normally held at BYU. Previous plans for the devotional were altered, as Bateman led the student body in a prayer for peace. Bateman was followed by Cecil O. Samuelson in 2003. Samuelson was succeeded by Kevin J Worthen in 2014.
