Obama Family Obsession, The Huxtables, and the Black Image on the Screen by Nordette, on BlogHer. I enjoyed following her links to YouTube clips of "Room 222" and "Julia"!
The Obama win didn't happen just because of a TV show, but it's possible America's acceptance of the Obama family and an African American as President of the United States may be correlated to the image of African Americans changing in fictional media. Our images shifted from slave, mammy, maid, butler, cook, clown, thug, drug-addict, pimp, hooker, rapist, drug dealer, and parasite on both the small and big screen to teacher, police officer, military leader, lawyer, doctor, judge, patriot, hero, and President of the United States.
Our transformation from more negative images to more positive images did not happen accidentally. African-American actors, directors, producers, and professors with the help of sympathetic white professionals in the entertainment industry worked hard to get positive images of African-Americans on the screen, and frequently attempts to present a better image met opposition.
