I'm not sure that's entirely true - as someone who hangs around in bookstores a lot, it seems to me that most of the successful authors these days (the novelists, anyway) tend to be women. I'm not sure why this is, but that's what it looks like to me. Also, most bookstores worth their salt will have a section devoted to gender issues, along with those of race. (At least, again, that's my experience, judging by the bookstores I've frequented.) If the bookstore is at all large, some of these sections can be HUGE. So in some ways, regular bookstores are actually more inclusive than the specialist ones, since they have books devoted to these specific issues as well as more general subject material. As to TV, that's a bit different. Throughout most of its history, TV shows have not really had the opportunity to be specialist - they've had to try to appeal to EVERYONE, as impossible as that is, to keep up their ratings and avoid being deluged with angry phonecalls - and, unfortunately, for a number of years the people most likely to make the angry phone calls were bigoted white people. Now that there are all these hundreds of channels available on cable, that's changed things a bit, but old habits die hard.
