Scoobidoo Were Are You!
Scooby-Doo, Where Are You! is the first (and flagship) incarnation of the long-running Hanna-Barbera Saturday morning cartoon series, Scooby-Doo. It premiered on September 13, 1969 at 10:30 a.m. EST and ran for two seasons comprised of 25 episodes, with its final first-run CBS episode airing on October 31, 1970.

Nine episodes from Scooby-Doo's 1978-79 season, first run on ABC, were originally broadcast with the 1969 Scooby-Doo, Where Are You! opening and closing sequences. The entire 1978-79 series (which completed its run as part of Scooby's All-Stars and was later syndicated as part of The Scooby-Doo Show) is sometimes marketed as a third season of the original "Where Are You!" series.

Scooby-Doo, Where Are You! was a breakaway hit for Hanna-Barbera and CBS, who quickly introduced similar cartoons to accompany Scooby-Doo: Josie and the PussycatsThe Pebbles and Bamm-Bamm ShowThe Funky PhantomSpeed BuggyJabberjawCaptain Caveman and the Teen Angels, and Fangface.

The series began airing reruns on Cartoon Network in June 1994. Reruns on the channel remained so popular, that it was one of the few remaining classic cartoons left on the channel when reruns finally ceased in December 2008. The series returned briefly for a marathon on the weekend of September 12–13, 2009, in commemoration of the show's 40th Anniversary. In October 2012, reruns returned to the network, remaining until September 2013.
