Gee like this is new. Basically you watch ads first, maybe answer a question or two to prove you are “real” and then you earn credits to watch shows for free. My 2 cents, why not just build the commercials right into the shows like “old TV’ did? The company doing this is called hitbliss and being cheap, I might check this out.
