I don't view a lot of TV in general, but don't think I can even remember the last time I saw a monoracial white couple in a TV commercial. I don't think it's very common anymore (luckily there is more representation of other races in  CHRISTMAS adverts now since the way non-whites were discriminated constituted a hate crime). Now it's basically always a mixed-race couple/family, particularly Black/White. It makes me really happy, it's so open-minded it makes me proud. Who do we have to thank for these changes?
