Teenage Mutant Ninja Turtles (2003)

Teenage Mutant Ninja Turtles is the second animated series based on the comic book series of the same name created by Kevin Eastman and Peter Laird. It was co-produced by Mirage Studios (the company that published the original comics) and 4Kids Entertainment, and originally aired on FOX from February 8, 2003 to October 27, 2007, and then on The CW from September 13, 2008 to March 27, 2010.

This series stuck closer in tone to the original comics than its longer-running predecessor, with several early episodes being direct adaptations of stories from the comics, but also included some new takes on the franchise (such as Shredder actually being an evil Utrom).

The first five episodes of this series were aired in reruns on Cartoon Network for the week of December 29, 2003 to January 2, 2004. Cartoon Network began regularly airing reruns of the series as part of the Miguzi programming block on April 19, 2004, though only the first 74 episodes were actually shown. Reruns of Ninja Turtles continued to air on the network through 2006, with a final marathon airing on March 24, 2007 to promote the CGI-animated TMNT movie that came out the previous day.

In 2009, the Ninja Turtles franchise, including this series, was sold to Viacom, bringing the Turtles under the Nickelodeon banner. However, the Turtles would eventually be seen on Cartoon Network again when it aired the 2014 live-action Teenage Mutant Ninja Turtles movie (which, ironically, was co-produced by Nickelodeon Movies) on October 3, 2021.
