Locast TV is a streaming service that provides you with free, no catch, access to your local broadcast stations in select U.S. markets.
You get access to many local broadcast channels including CBS, ABC, Fox, NBC and more.
Locast TV is a non-profit which technically allows them to rebroadcast local signals for free.
This loophole was expected to be challenged in court by the broadcasters, but AT&T just donated $500,000 to the non-profit. With the largest pay tv provider and their subsidiary Warner Media owning so much programming this changes the game.
How long will it be free? Maybe forever.
Is it legal. Yes, the current wording of the law is technically being followed.
Is there a catch? Streaming costs bandwidth, so donating $5/mo if you use it regularly is encouraged but not required.
