African-American representation in Hollywood

The presence of African Americans in major motion picture roles has stirred controversy and been limited dating back decades due to lingering racism following slavery and segregation. "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." While African American representation in the film industry has improved over the years, it has not been a linear process; "Race in American cinema has rarely been a matter of simple step-by-step progress. It has more often proceeded in fits and starts, with backlashes coming on the heels of breakthroughs, and periods of intense argument followed by uncomfortable silence."
