Really interesting and radical idea. Having content specifically for a black audience seems so controversial at first but could be a great way to include black people more in pop culture. I think there is definitely demand for this: both from producers and viewers. If such a service existed it may even help cross-cultural knowledge sharing.

I read a good comment here from a netflix employee about the technical challenges. DRM seems like its going to be a bitch. Would be a cool startup to work for though
