Black people: 4% of population but >50% of TV ads
South Asians: 9% of pop. but 17% of ads
East Asians: 1% of pop. but 8% of ads*
Two other important issues:
1. White men grossly under-represented
2. When featured, white men are often portrayed negatively (as dim, helpless, incompetent or bad). One will almost never see a black man portrayed negatively
Why do people think they are being bombarded with ethnic minorities in advertising? Because they are.
Almost every advertiser wishes to demonstrate their DEI credentials. Thus, should a commercial break feature 6 adverts, there's a strong chance that every one of those 6 adverts will feature black and Asian people.
Seeing ad after ad pushing the same progressive / DEI narrative will inevitably lead many - if not most - people to think they are being bombarded and manipulated.
