Will broadcasters including Fox and CBS make good on threats to take their programming to pay TV if the courts say that Aereo can stream their over-the-air signals without compensating them? Probably not, Aereo CEO Chet Kanojia tells CNBC. Companies wouldn’t want to endanger their local newscasts, a big attraction for viewers. Besides, broadcasters ultimately should see Aereo as an ally: Many viewers want a simple way to replace today’s pay TV with a Web-delivered combination of library and live programming — and Aereo can help with the live part.
