Well when it comes to magazines, people will buy it if they're interested in the person gracing the cover. But then you'd have to remember the magazines target market. Teenage white girls most likely aren't gonna buy an issue of Seventeen Magazine if Ciara's on the cover, but if it were Rihanna, they'd definitely buy it because they're most likely interested in her. And Rihanna and Ciara's complexions are kinda similar...just like a black woman most likely wouldn't buy an issue of Essence Magazine if Heidi Klum were on the cover...

BUT we ALL know that the skinny blonde-haired, blue-eyed chick will be worshiped before the brown, olive colored or yellow girls....
