The Pac-12 Conference, which until July 1 was known as the Pacific-10 Conference, announced today that it is forming a national and regional sports network to launch in August 2012 that will broadcast 850 sporting events a year, including every football and basketball game, with subscribers also able to watch games on mobile and the iN Demand VOD platforms. A national network will join six regional channels — Washington, Oregon, Northern California, Southern California, Arizona and Mountain — to cover the six states in the college sports conference, which has added the University of Colorado and the University of Utah to its roster to give it 12 members. The 350 nationally televised games will be split with Fox and ESPN, which already have a long-term contract with the conference worth $3 billion. Comcast, Time Warner Cable, Cox Communications and Bright House Networks also are part of the venture, with satellite and telco platforms expected to come into play later. At its launch, the conference said the network will reach about 40 million cable customers nationwide.
