Black Comedy in America

I tried to find an episode list before I posted this, alas I only found episode 1 and 2. I hope I get the chance to change this rating down the road. I do not understand why they did not start with, "Fox, Pryor, Murphy, Rock, Morris. Black comedy started before the 90's, hell... Where is Sandford and Son, Good Times, What's Happening, The Jefferson's? It's like they just forgot the 70's and 80's. These performers and shows deserved to be first and noted, not just "blips," in someone else's episode. I hope somewhere down the road the "real OG's" get an episode, however it should have been chronological and they should be first.
