over at TVequals.com has illustrated the racial diversity of the Fall 2012 TV season.
NBC leads the pack as the network with the most diversity in its scripted programming. ABC and Fox are in the middle and CBS and CW are in the bottom.
NBC was the only network with an actor of color in every single one of its series. However, the analysis doesn’t look at the number of appearances or number of lines for each actor.
For example, Fox got a D grade but they’re also the network with “The Mindy Project” that stars “Mindy Kaling.” A show with a women in the leading role goes a long way compared to supporting actors of color who may just have a couple of lines in each episode.
