This is a great idea, but how do you protect yourself from Netflix and Amazon simply deciding to eat your category? It seems like as the 800 pound gorillas in the market, there's nothing preventing them from simply beefing up their catalogs and adding some categories to do the same thing.
FWIW, Amazon does offer Middle of Nowhere (the film in the article screenshot) for rental (no free streaming with Prime) and the "Customers Who Watched This Item Also Watched" is all African-American films as well. That said, it's not clear how deep their catalog goes, and they don't actually have an African-(American) category one can browse.
(Also, why did you write your last name in ALL CAPS? I've seen people do this before, but I've never understood what the convention is trying to achieve).
