Well look how almost every Zune commercial has folk-y indie rock going on, with white/hispanic kids breakdancing. It's as if the dancing is cool enough, but they don't want to offend the middle of the country with angry black music. There are maybe 6 black people across 5 commercials. Two dogs. No Asians. So: Dogs are a more important demographic to Zune marketing than Asians? There are about a hundred different white folk partying down like it's a minority-free Wonderland.
Even Apple knows to make everyone the same color in their animated ads, with cheery united colors of Benetton backgrounds.
Oh well...at least the Zune comes in black, brown, and white.
