The Pacific-12 Conference, which has made no secret of its desire to create a network to showcase its newly expanded league, announced Wednesday that it would create six regional channels and a national one.

There will be a network for each of the six regions that have two colleges: Washington, Oregon, Northern California, Southern California, Arizona and Mountain. All will carry national programming, including 35 football games, more than 100 men’s basketball games and 40 women’s basketball games, as well as the Olympic sports that traditionally have gotten little or no television exposure.

The regional networks will be carried in Pac-12 markets on expanded basic cable; the national network in Pac-12 states will be shown on digital basic, and the national network will be seen on digital sports tiers, which require extra fees, in non-Pac 12 states and markets. So far, the conference has signed the cable operators Time Warner Cable, Comcast, Cox and BrightHouse to carry the networks, and expects to add satellite and telephone companies.

“It’s such a unique opportunity,” said Larry Scott, the Pac-12’s commissioner. “We’ve had a national brand, but the tribal nature make college sports very local. So this is an attempt through the unique structure of our conference and the cable industry to super-serve fans in a hyper-local way.”
