Scooby Doo, Where Are You! [3] 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.\r Nine episodes from Scooby-Doos 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).[4] The entire 1978–1979 season (which completed its run as part of Scoobys 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.
