On October 21, 2009, it was announced that cable channel Nickelodeon (a subsidiary of Viacom) had purchased all of Mirage's rights to the "Teenage Mutant Ninja Turtles" property. Mirage retains the rights to publish 18 issues a year, though the future involvement of Mirage with the Turtles and the future of Mirage Studios itself is unknown. Nickelodeon has developed a new CGI-animated TMNT television series and will partner with fellow Viacom company Paramount Pictures to bring a new TMNT movie to theaters. The TV show premiered on Nickelodeon on September 29, 2012. However, in June 2012, Paramount shut down their planned production due to script issues, pushing their release date out until May 2014.
