Karen Thomas, an executive editor at Grand Central Publishing, answered three questions from Publisher's Weekly. Of the three, this was most interesting:

PW: How do you perceive the differences between black and white readers?

KT: I think with some titles, depending on the genre, the gap is closing. A lot of the books I’ve been dealing with are targeted somewhat to a younger market, and because, I think, of the hip-hop generation, the differences aren’t as great as they used to be…What I do know is that people love pop culture, whether you’re black or white. So if you put a pop culture book out there, it’s going to sell across the board. When you have different celebrities, their core market may be African-American, but it crosses the board.
