Teenage Mutant Ninja Turtles has been a global hit, maintaining impressive numbers across the network’s ratings and our digital and consumer products platforms,” said Russell Hicks, president of content development and production at Nickelodeon. “While new episodes will continue to debut on Nickelodeon, we look forward to propelling the momentum with a fourth season for our loyal fans.”

Ciro Nieli executive produces the series, which premiered September 2012 to 12 million viewers in its premiere weekend. Teenage Mutant Ninja Turtles is currently wrapping its second season, which ends later this summer.

The news comes at an opportune time for the Teenage Mutant Ninja Turtles franchise, as Paramount readies the Aug. 8 opening of the Michael Bay-produced live-action feature starring Megan Fox and Will Arnett. It was directed by Jonathan Liebesman and written by Josh Appelbaum, Andre Nemec and Evan Daugherty.
