Variety reports: “The 4 major broadcast networks have filed a lawsuit against Locast, a New York-based nonprofit that streams local broadcast programming over the internet. In their lawsuit, ABC, CBS, NBC Universal and Fox allege that Locast violates their copyright by retransmitting their programming without permission, likening it to Aereo, the TV retransmission startup that shut down in 2014 as the result of a similar lawsuit.”
