When Boondocks was picked up in it's first year by AdultSwim, little did we know what an impact it would have in the animation community.

Originally the fourth season was anounced back in April 2011 with a 2012 air date in mind. But it was later pushed back all the way to April 2014.
And one week before the season begins Adult Swim released the first and presumably only trailer of the show's fourth and final season.
