Two major cable-TV operators that also own several cable networks are refusing to sign deals that would allow those networks to be carried by Verizon's new video service, Daily Variety reported today (Wednesday). The two are Comcast, which owns E! Entertainment, Outdoor Life, the Golf Channel and several regional sports networks, and Cablevision, which owns AMC, WE, IFC, the MSG sports network and Fox Sports New York. According to the trade publication, the two cable giants are concerned that their cable systems will lose customers to Verizon if their channels are carried by the phone company's Fios fiber-optic TV service.
