Corporate Racial Bias

I'm beginning to see more and more racial bias within television commercials. Especially on ESPN who is owned by the conglomorate ABC. Each and every commercial I see portrays white people and families as thee main characters within their advertisement, and cast minorities as extras. I'm not saying that blacks, asians, and hispanics are not playing the leading role ever, but the statistics far outweigh those of whites. I'm sure if I were to watch any prolonged television of BET or MTV which has a different audience, the statistics would skew towards the middle or the other side.
