I'll just post what I said about this earlier:
this is why there can never be a black controlled entertainment industry because people are too concerned about getting love from cacs and believing that the grass is greener on the side.
I've fantasized and scenario'd for a while what your talking about and the unfortunately the conclusion I keep coming to is..Black controlled entertainment industry wouldn't start off like the Negro Leagues...it WOULD BE the Negro Leagues.
And like the MLB, Hollywood would marginalize it and use it as farm system to cherry pick the best talent all the while blocking distribution or them being distribution for it which makes it a subsidiary of cac industries. Blacks would use it to build up a resume just so they can walk across the street to get those higher paying gigs in hollywood. They would rather fly coach in the white mans plane that sit in first class in their own.
There would very little loyalty and as the more popular more talented blacks are offered more money by cacs to come over the fence they would say its just business draining black hollywood of its best more popular talent (becuz we know an aspect of their deal would be youre either play with us or you don't..ever)
And the Black Hollywood would go the way the Negro Leagues went and eventually peter out after 10 or so years or stay marginalized until its novelty factor was no longer viable.
and this shows how kendrick lamar is on the road to the sell out...last year was complaints and this year is compensation...give the negroes extra to keep them compliant. It doesn't mean anything really but a little bit of acknowledgement from the white establishment goes a long way and they know it.
