["Have you noticed an increase of race mixing ads aimed at kids?"]

It is certainly the 'norm' nowadays in the world of advertising. If they do show a white without the insinuation that there's an Orc hanging out of the back of it, they usually pick a red head to still represent a minority.
You never see an Indian/Pakistani girl with a white/black bloke of course. If they did that they'd have to have the 'uncles' loitering in the background sharpening the knives...
