History of politically correct terms for Black Americans

In chronological order:

* Negro
* Colored (see NAACP)
* Black
* Afro-American
* African-American
* Person of Color

Even though all of these terms mean the same thing, some are now deemed offensive. Over time, especially in conservative circles, Americans have been moving to a color-blind society, where achievement matters and race is irrelevant. Moving against this trend is the rise in affirmative action.
