Black Characters in Search of Reality - NYTimes.com: Through most of the 20th century, images of African-Americans in advertising were mainly limited to servants like the pancake-mammy Aunt Jemima and Rastus, the chef on the Cream of Wheat box. Imagine a Rip Van Winkle who fell asleep during the era of the Negro as household retainer and woke up in 2012. He would be struck speechless by billboards and commercials featuring affluent black people advising consumers on pharmaceuticals, real estate, financial services and the virtues of owning expensive cars. This kind of transformation has yet to take hold in the dramatic arts.
