Diversity Among Winners at the Oscars

A lot of attention was paid to the lack of diversity among Oscar nominations in 2015.  This video by Bard Edlund shows how many black, Hispanic, and Asian winners there have been throughout history (including this year), across four main categories -- best actor/actress, supporting actor/actress, writing (original and adapted screenplays), and directing.  You can see why a lot of eyebrows continue to be raised.
