The comic book industry is dominated by white people, like a lot of industries in the western world. And for a long time the most popular characters published by DC and Marvel have been written and drawn by a very narrow spectrum of people.
There remain more hurdles for people of colour getting into the comic book industry than others, but one way to show that they represent voices that we want to hear, is to vote with our wallets, and buy and read books by a variety of creators from different backgrounds.
Fans often fallen prey to the laziness and tunnel vision of sticking to a small subset of writers that they repeatedly seek out, and the industry dynamic is such that most of whom are likely to be white men. But that's no reason to continue to do so, especially with the resources available to us these days.
To that end, we've put together a list of some black artists and writers worth checking out, who have a body of work to choose from, but by all means do your own further research into black creators. There are plenty of great books based around black issues such as the civil rights movement, but just as many involving standard superhero escapism.
