The ol' web slinger has really got himself in deep trouble this time, gang.
The first Spider-Man animated television series ran from September 1967 to June of 1970. It was jointly produced in Canada (for voice talent) and the United States (for animation). This first animated adaptation of the Spider-Man comic book series, created by writer Stan Lee and artist Steve Ditko was extremely popular and still sells DVDs 40 years later!
Spider-man first aired on the ABC television network in the United States and went into syndication at the start of the third season. Seasons two and three were created by legendary animator Ralph Bakshi (Wizards) in New York City. In season two and three Bakshi adopted a darker tone for the show with darkly colored settings, psychedelic images, and atmospheric music.
