The fight over Aereo is moving to Utah.
On Monday afternoon, Fox Broadcasting Co., Sinclair Broadcast Group and Local TV filed suit in federal court in Utah against Aereo, the start-up company that streams broadcast TV signals to consumers via the Internet.
Broadcasters have already challenged Aereo on copyright violation in New York and Boston. This suit, filed in U.S. District Court in Utah, where Aereo recently launched its service, makes similar allegations.
Aereo, whose financial backers include media mogul Barry Diller, provides access to broadcast TV signals via smartphones, tablets and Internet-friendly TVs. For a fee, Aereo subscribers get a tiny antenna that can pick up the signals of broadcasters. The antenna and a cloud-based digital video recorder can hold up to 40 hours of programming.
