Life Has Yet to Imitate Art
For all the talk in the industry about the lack of minorites in positions of importance, at least stock photography has long attempted to embrace multiculturalism, presenting us with a rosey picture of racial harmony and good will among men and women. (Although I'm not so sure this is an actual picture from the 70s from Getty Images. I refuse to believe even the sleaziset of used car dealers actually went to work dressed like this. Seems a little "too" 70s.)
We see it everywhere, especially in college brochures. So there's obviously an awareness that in order to appeal to all targets, you must represent all targets. Or is it just White Ad Man's Guilt that causes ads to reflect a mini United Nations?
