Commissioner Larry Scott said on February 9, 2010, that the window for expansion was open for the next year as the conference began negotiations for a new television deal. Speaking on a conference call to introduce former Big 12 commissioner Kevin Weiberg as his new deputy, Scott talked about possibly adding new teams to the conference and launching a new television network. Scott, the former head of the Women's Tennis Association, took over the conference in July 2009. In his first eight months on the job, he saw growing interest from the membership over the possibility of adding teams for the first time since Arizona and Arizona State joined the conference in 1978. In early June 2010, there were reports that the Pac-10 was considering adding up to six teams to the conference: the University of Texas, Texas A&M University, Texas Tech University, the University of Oklahoma, Oklahoma State University, and the University of Colorado. On June 10, 2010, the University of Colorado Boulder officially accepted an invitation to join the Pac-10 Conference, effective starting with the 2012–2013 academic year. The school later announced it would join the conference a year earlier than previously announced, in the 2011–2012 academic year. On June 15, 2010, a deal was reached between Texas and the Big 12 Conference to keep Texas, Texas A&M, Texas Tech, Oklahoma, and Oklahoma State in the Big 12. Following Texas' decision, the other Big 12 schools that had been rumored candidates to join the Pac-10 announced they would remain in the Big 12. This deal effectively ended the Pac-10's ambition to potentially become a sixteen-team conference. On June 17, 2010, the University of Utah officially accepted an invitation to join the Pac-10 Conference, effective starting July 2011. Utah was a member of the Western Athletic Conference (WAC) with Arizona and Arizona State before those two left for the Pac-10 in 1978. The Utes left an expanded WAC with seven other schools in 1999 to form the new Mountain West Conference. Utah became the first "BCS Buster" to join a BCS conference, having played in (and won) two BCS games beforehand. On July 27, 2010, the conference unveiled a new logo and announced that the Pac-10 would be renamed the Pac-12 when Utah and Colorado formally joined in July 2011. On October 21, the Pac-12 announced that its football competition would be split into two divisions—a North Division comprising the Pacific Northwest and Bay Area schools, and a South Division comprising the Mountain Time Zone and Southern California schools.
