The major broadcast networks today sued the makers of Locast, a nonprofit organization that provides free online access to broadcast TV stations. The lawsuit filed by ABC, CBS, Fox, and NBC seeks financial damages and a permanent injunction that would shut Locast down.

Broadcast TV networks are available for free over the air with an antenna. But selling the rights to retransmit those signals in other ways is a big business. Broadcasters reportedly collected $10.1 billion in 2018 via retransmission fees they charge cable and satellite TV companies.
