We knew ESPN wasn't happy with Verizon's recently announced flexible TV plans, and now it is ready to take legal action on the matter. According to CNBC, The Worldwide Leader in Sports is suing Verizon over the FiOS Custom TV package, only days after letting it be known that it objected to it. ESPN isn't alone, either: last week, Fox Sports and NBC also came out against Verizon's offering, which lets subscribers pick channels based on their viewing preferences. In a statement, ESPN said, "We simply ask that Verizon abide by the terms of our contracts." Verizon, meanwhile, has said that FiOS Custom TV does not violate any contract agreements with the TV networks.
