Scooby Doo, Where Are You!  is the first incarnation of the long-running Hanna-Barbera Saturday morning cartoon series Scooby-Doo. Created by Joe Ruby and Ken Spears, it premiered on CBS September 13, 1969, and ran for two seasons for a total of 25 episodes. Its final first-run episode aired on October 31, 1970.

Nine episodes from Scooby-Doo's 1978-79 season, first run on ABC, were originally broadcast using the 1969 Scooby Doo, Where Are You! opening and closing sequences (in an attempted stand-alone series revival that was cancelled). The entire 1978–1979 season (which completed its run as part of Scooby's All-Star Laff-A-Lympics and was later syndicated as part of The Scooby-Doo Show) is sometimes marketed as the third season of the original Where Are You! series.

Origin

Scooby Doo, Where Are You! was the result of CBS and Hanna-Barbera's plans to create a non-violent Saturday morning program that 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 (the most notable of which was the downplaying of the musical group angle borrowed from The Archie Show). However, the basic concept—four teenagers (Fred, Daphne, Velma, and Shaggy) and a cowardly, clumsy Great Dane (Scooby-Doo) solving supernatural-related mysteries—was always in place.
