Brodcasting Whitnesss?

I read an article today and the title of it was called "Brodcasting Whiteness". From the title of this article i could already tell that there were going to include something about being racist in there. The article basically was talking about how TV shows nowadays do not include enough races in there such as Hispanic, Black, Chinese, Asian, people. When you really think about it there is not enough race in TV shows. The excuse for this is that producers put the races that other people wan to see thats why there is more white people than other races on Tv. I think this is not a good excuse and something needs to be done about it. They also said that people would not find the most shows interested if not enough people were not in the shows. TV series like Law and Order: Specials Victims Unit has former rappr like Ice-T and a lot of people seem to enjoy this show. I think if this was to be brought over on the news or something this article would get a lot of negative reviews because things like this shouldnt be happening. I think this is encouraging racism and something should be done about it.. If i were a producer i wouldnt look for specific races i would look for talent, what people are good at doing, isnt this what the hollywood thing is all about.. ?
