Adventures of Sonic the Hedgehog was created by DiC Entertainment, who produced a total of 65 episodes for its first season. The first episode was "Best Hedgehog" (shown Sept 6) and the last was "Hero of the Year" (shown Dec 3). DiC ceased production to spend more time on it's other cartoon, "Sonic the Hedgehog", a series launched on ABC's Saturday morning line-up. A second season of "Sonic the Hedgehog" (commonly refered as the "Lost Season") had begin preliminary development, but it never got aired. Two other episodes in that season were in the works prior to the cancellations.
This wasn't to be the end of AoStH, however, for DiC created one more episode in the winter of 1996, "Sonic's Christmas Blast" - which ended up being a strange mix of AOSTH and SATAM, another Sonic the Hedgehog cartoon show.
Adventures of Sonic the Hedgehog was most recently shown weekdays at 8:00am Central Time on Toon Disney (a digital cable/sattelite channel). AoStH villains also appeared one weekend on "Chillin' with the Villains" program hour - Robotnik was even on their commercial for it.
