when did the pac 8 become pac 10
Pac-12 Conference In 1978, the conference added Arizona and Arizona State from the Western Athletic Conference, becoming the Pacific-10 Conference or Pac-10. The invitations to the schools were extended in December 1976,[81] and the expansion formally announced in May 1977.[82]
Big East Conference (1979–2013) On October 28, 2011 it was announced by the Big 12 Conference that West Virginia accepted its invitation to join, with membership beginning in 2012. This timeline was challenged by the Big East, and countersuits were launched by the school and conference. Eventually, a settlement was reached with allowed West Virginia's departure for 2012 in exchange for sizable compensation.[21] Syracuse and Pittsburgh then used the acquiescence of the Big East to West Virginia's departure to challenge the validity of their own commitment, and the Big East agreed to a settlement with both schools in July 2012 to allow their departure for the 2013 academic year.[22][23]
