I guess I'm thinking mainly about franchise characters that keep getting sequels and reboots and not so much television. Maybe that's where the disconnect is between you and me on this issue. The reason I'm looking at it from that narrow view is because the white characters that are being turned black. Probably even more often they are being changed from white male to some type of female. That's what's triggering me to even think about this. In doing so it occurred to me that a lot of black characters are very much centered around their race and you really couldn't change the race of that character without completely changing their nature. My thoughts on this issue might not be complete or 100% fair but I do think I'm pretty accurate. I mean, I'm giving you stuff like Batman, and James Bond.....or maybe Luke Skywalker. You are giving me forgettable characters from a shitty 90's sitcom. lol. Where is the good stuff?
Edited to add......
I'm trying to be fair to you here but after reading your most recent post a second time I think you are just too dumb to follow what I'm saying. 
Yeah. I'm so dumb I can't even finish a newspaper article before whining for 5 pages about something that's not happening.
Meanwhile, you asked the question and I responded. I actually responded initially with an explanation and examples of why creating franchise characters was prohibitively difficult for minorities, and instead of following that line of convo, you asked me for any examples of black creations. In the follow up post, I gave you examples and instead of saying you were talking exclusively about franchise characters, you came up with a laundry list of reasons why those black creations didn't count as black creations. I addressed that, and sarcastically said that soon enough you'd be claiming comedy doesn't count or only a black version of James Bond counts. Instead of saying that's what you were talking about in the first place (which you weren't), you went back to your argument that those examples don't count as creations, and that no character counts if it has any racially specific element (which is insane.) But despite all that, you actually meant what I sarcastically asked you all along? Which just goes to show, you're just making up new excuses with each post.
If you were asking "why haven't blacks created a black version of James Bond or Batman" you could have veered into that at any point, but you chose not to. Besides, anyone with even a casual understanding of how the entertainment industry has worked for the last 50 years shouldn't even have to ask.
And no, I didn't give you examples of shitty forgettable 90s sitcoms. I gave you examples megasuccessful properties that spanned time. The Cosby Show was the highest rated show at its peak. Elmo has been far and away most popular and profitable character on that show for decades. The Boondocks is a multimedia franchise. Power is the most popular show on Starz and has driven that channel's growth for the last 5 years. There is an endless list of black writers, producers, creators,etc I could've referenced, but these properties fit the discussion well because they were popular and impactful. I could've talked about someone like Shonda Rhimes, but chose not to as her most popular show (which has been running for like 15 seasons) features a white actress in the lead.
