Many short films produced by Sam Register air on the show; they are mainly comedy. In the first season, these included New Teen Titans, S.B.F.F. and DC’s World’s Funnest from Aardman Studios. Season two saw two additional short series: JL Animals and Amethyst: Princess of Gemworld.
On October 13, 2012, two weeks after the block had returned from a summer break and ten hours before the block was supposed to air, the block was ceased from the schedule by Cartoon Network; an hour of DreamWorks Dragons was shown on Saturdays with Johnny Test on Sundays. DC Nation workers were told about the action by fans. Later that day, Cartoon Network and DC Nation's Facebook and Twitter profiles stated that the block had been put on hiatus and will resume airing in January 2013. An online petition was started that day to bring back the block by the end of the year and reached its first goal of 10,000 signatures on October 15. Green Lantern episode "Steam Lantern" and Young Justice episode "Before the Dawn", episodes that had been scheduled to air, were released to the iTunes Store and became the top two television programs of that day, and became available on Amazon.com on October 16. The episodes have since been removed from the stores. No official explanation has been given for the extended hiatus. Currently, All DC Nation seems to consist of is Teen Titans Go and various shorts. Young Justice, Green Lantern and Beware the Batman were all canceled with little or no information given to the fans about these shows other than a rumored report that the DC parent company didn't feel these super heroes were meant for kids anymore and so they pulled funding for the cartoons.
