Cable customers of Cablevision Systems Corp. in New York and Philadelphia could face a second weekend of blacked out Fox content as a result of failed carriage negotiations. News Corp., owner of Fox, pulled its signal from Cablevision distribution on Oct. 16 after the two parties could not reach an agreement on carriage rates for the over-the-air channel. Cablevision has three million television subscribers in New York and Philadelphia affected by the blackout. Fox issued a statement Friday telling customers to change cable providers or buy over-the-air television antennas if they want to watch popular programming over the weekend, such as a playoff baseball game between the Philadelphia Phillies and San Francisco Giants as well as National Football League coverage. Fox says it will not enter binding arbitration, which would put the channel back on the cable system until a deal is reached. Fox says it wants to settle the dispute through direct negotiation. The U.S. Federal Communications Commission sent a letter to the two parties Friday expressing concern about the impact of the blackout on consumers and asked that they demonstrate they are meeting obligations to negotiate in “good faith.” The American retransmission consent regime, which allows over-the-air broadcasters to pull their signals if negotiations fail, is similar to the CRTC’s value-for-signal regime now being considered by the Federal Court of Appeal.
