The very first (and flagship) series of Hanna-Barbera's Scooby Doo series. Scooby-Doo, Where Are You! was the result of CBS and Hanna-Barbera's plans to create a non-violent Saturday morning program which would appease the parent watch groups that had protested the superhero-based programs of the mid-1960s. Originally titled Mysteries Five, and later Who's S-S-Scared?, Scooby-Doo, Where Are You! underwent a number of changes from script to screen. However, the basic concept—four teenagers (Freddie, Daphne, Velma, and Shaggy) and a cowardly, clumsy Great Dane dog (Scooby-Doo) solving supernatural-related mysteries—was always in place.
