The targeting of blacks in commercials isn’t flattering or preferential treatment for them; it occurs because advertisers believe they are one of the last groups that responds to goofy Jedi mindtricks like TV commercials. It also reflects the fact that they are among the last holdouts watching regular TV.

The whites that watch get a good laugh at the goofy role reversals, and blacks go out and buy things...

I've read other studies that claim blacks are far more likely to purchase consumer goods and that they are a highly sought demographic for people selling stuff, so that sort of makes sense.

That is probably it. When in doubt, follow the money.
