The IAC chief, a major investor in Aereo, says that’s what’s behind recent threats by Fox, CBS, and Univision execs to turn their broadcast networks into pay TV channels if they lose their copyright infringement case against the streaming service. “The law of the U.S. is that if you have an antenna, broadcasters must provide a signal that you can receive without any interference,” Barry Diller told Bloomberg Television‘s Willow Bay — who happens to be married to Disney CEO Bob Iger, whose company is part of the group that’s suing Aereo. Diller adds that his decision to buy Newsweek was “a mistake.”
