Associated Press: ESPN is suing Verizon in an escalating clash over how the popular sports channel is being sold in a discounted pay-TV package. The complaint alleges Verizon is breaking its contract with ESPN by unbundling the sports channel from the main lineup of Verizon’s FiOS TV. The legal showdown could have ripple effects on how other pay-TV programming is packaged. Cable and satellite services are scrambling to retain subscribers as the advent of Internet video spawns new and less expensive ways to stay entertained and informed.
