A 1:00 short featuring Plastic Man, which will be part of the DC Nation programming block that premieres March 3 (see “DC Nation Programming Block Set”), has been released through the Nerdist Channel.  The Saturday morning DC Nation block will launch with Green Lantern: The Animated Series and Young Justice, plus various shorts featuring DC characters.  The Nerdist Channel was launched on YouTube late last year (see “Geek Culture Key to Streaming Services”).
