The newly created product of a contract between four major cable providers and Pac-12 Commissioner Larry Scott, the Pac-12 Networks launched at 6 p.m. PDT on Wednesday.

The enterprise consists of a national network as well as six regional networks that will broadcast as many as 850 live events this upcoming year. The events include all conference football and men’s basketball games.

The Pac-12 Networks will also eventually be available on iPads, iPhones, PCs and Androids. The timeline for those launches is yet to be determined.

Time Warner, Comcast, Bright House and Cox are the four cable providers that have agreed to the deal, while DirecTV and DISH are still discussing potential contracts with the Pac-12.

Bay Area viewers who subscribe to Comcast will be able to access the regional network in standard definition on Channel 433 and high definition on Channel 823.
