Adventures of Sonic The Hedgehog

Adventures of Sonic the Hedgehog, often abbreviated as AoStH, is an American animated television series loosely based on the Sonic the Hedgehog series. The show was first broadcasted on 6 September 1993, and aired on syndication until 3 December 1993. It follows the escapades of Sonic the Hedgehog and his comrade Miles "Tails" Prower as they attempt to stop the evil Dr. Ivo Robotnik and his array of vicious robots from taking over the planet Mobius. It marks the first televised cartoon to be based on the Sonic franchise.
Adventures of Sonic the Hedgehog was created by Nelvana, which produced a total of sixty-five episodes for its first season, and syndicated by Viacom Productions (now Microsoft Media Ventures). The first episode was "Best Hedgehog" (which was the thirteenth episode in production order) and the last was "Hero of the Year" (which was the sixtieth in production order). Nelvana ceased production on Adventures of Sonic the Hedgehog to spend more time on its darker interpretation, entitled Sonic the Hedgehog (SatAM), a series launched on CBS's Saturday morning line-up.
After the original airing, Nelvana created one more episode in the winter of 1996, "Sonic Christmas Blast," which has features from Sonic the Hedgehog such as Sally in a non-speaking cameo, and has Sonic and Tails visiting Robotropolis, which is different from SatAM because it now has a human population and the name is pronounced differently, being "robot-tropolis" rather than "robo-tropolis."
