Eventually McDuffie co-founded Milestone Media and explained this about it:
"If you do a black character or a female character or an Asian character, then they aren't just that character. They represent that race or that sex, and they can't be interesting because everything they do has to represent an entire block of people. You know, Superman isn't all white people and neither is Lex Luthor. We knew we had to present a range of characters within each ethnic group, which means that we couldn't do just one book. We had to do a series of books and we had to present a view of the world that's wider than the world we've seen before."
Milestone released it's comics through DC comics and with McDuffie as editor-in-chief, he co-created Static amongst other characters. When Milestone stopped releasing new comics, McDuffie's character Static got his own show,Static Shock,which McDuffie was hired to write and story-edit on the series, writing eleven episodes.
