This series was created by the American animation company Hanna-Barbera, and was introduced to generations of children on September 8th, 1969 as Scooby-Doo, Where are you! Prior to its debut, the show was pitched as a humorless and scary cartoon series filled with terrifying haunted houses and monsters. What is even more surprising is that the star canine was presented as a mere supporting character. Of course, this concept came to be reworked. As a result, it became one of the longest running animated series of all time, containing a unique mix of mystery, adventure, horror and comedy.
