Fox Broadcasting parent News Corp. announced today (Feb. 22) that it will launch a new mini-network this fall called My Network TV that will supply programming to stations left without a network after the merger of UPN and WB. My Network TV’s list of affiliates includes 10 major market stations, but no San Francisco affiliate so far. It remains to be seen whether KBWB Channel 20, which lost the WB network, will get the new network, or whether it will go to KRON Channel 4, which has been without a network since losing NBC three years ago, or possibly KICU Channel 36, sister station of Fox affiliate KTVU Channel 2. The network will be headed by Roger Ailes, who built the Fox News Channel into the top-rated cable news network. All the News Corp. properties will promote the new network, especially the popular MySpace.com web site the company recently bought.
