BET worked. CrunchyRoll worked. I think the service has a good chance of making it if there's demand in this niche and they focus on delivering where it's strongest. If they stream to U.S., too, we might also see some interesting movies and culture we'd otherwise not be exposed to. Regarding Netflix, they might compete but I doubt it given what the co-founder has said. More likely, a company like Netflix would acquire them to inherit and exploit the market they created. That's just my guess.
Good luck, Ludovic.
