TV streaming iPad app and there have even been whispers of cease-and-desist letters in the offing, Fox has put a request to have its channels excluded in writing. At issue is whether or not their agreement allows Time Warner to provide the channel on devices other than the TV -- while TWC is confident it does since it only works within the customer's home, the networks would apparently like to renegotiate before conceding anything. Senior VP of Fox Networks Group Scott Grogin confirmed the letter was sent but did not reveal any details about its contents. Following the battle plan of its last battle with Fox, Time Warner Cable has preemptively put up a IWantMyTWCableTVApp site asking customers to show support for the TWCable TV app against the networks. We'll wait to see who blinks first and remember that Dish is already slinging channels to tablets with wild abandon while Comcast and Cablevision have plans for similar implementations on the way.
