Chase Carey, COO for media giant News Corp. (NWS), said the company may move its Fox broadcast TV network to cable to keep its channel off online services such as Aereo. Speaking at an NAB event in Las Vegas, Carey called Aereo's use of Fox's signals "disappointing," Reuters said. The broadcast networks have sued — unsuccessfully thus far — to block Aereo. News Corp. plans to split Fox Entertainment from its newspaper operations in June. News Corp. shares rose 2.5% to 31.41.
