Not just TV. My bank’s website has a carousel of rotating images and most have a person in the image. 3 out of 4 will be black or hispanic. This area if 97% white.
I call it the “Unicorn technique”.
The local bank uses a picture of a light-skinned black man holding a baby.
Our area is totally segregated—the suburbs are virtually all white—cannot remember when I saw any black person in a suburban bank.
In the big city there are a lot of blacks in the bank, but they are dark-skinned, almost no light-skinned blacks to be found.
As for babies, their black mothers in the city are almost all single moms—the fathers disappeared long ago.
The light skinned black father with a baby is a Unicorn—never been seen anywhere in the area!
My wife doesn’t believe me that this is a thing, and when commercials play, I point out the complete lack of white males. Those who are often in commercials are cast as buffoons. This isn’t in my head. It’s definitely happening.
