The actors are black... the actresses are White.

Commercials for some time now have been pushing, pushing, pushing the black man with a White woman. EVERYWHERE. Doesn't even have to be any kind of implied romantic relationship.... just a "random" White woman with a "random" black man. Almost EVERY commercial, without fail. Just look. At virtually any commercial. Could be for a car, potato chips, a restaurant, breath mints, insurance, anything. You will almost invariably see black man, White woman.

They have now begun showing commercials with White men (or rather... males) with black (or usually, high-yellow) women. It took them longer to start doing this, and it's still not nearly as prevalent, because basically White men just ain't gonna go for it. Unfortunately, White women often do.
