The document discusses how representations of race in media have changed over time to reflect societal changes. It uses the example of the Aunt Jemima logo, which originally depicted a racist "mammy" stereotype in blackface but underwent several revisions to become less offensive as attitudes toward race evolved. The document also notes that popular black celebrities today tend to have lighter skin and straighter hair than in the past, though representations are growing more diverse with stars like Lupita Nyong'o gaining prominence.
