Scooby-Doo is an American media franchise based around several animated television series and related works produced from 1969 to the present day. The original series, 'Scooby-Doo Where Are You' was created for Hanna-Barbera-Productions by writers Joe Ruby and Ken Spears in 1969. This Saturday morning cartoon series featured a talking Great Dane named Scooby-Doo and four teenagers — Fred jones, Daphne Blake, Velma Dinkley, and Norville "Shaggy" Rogers — who solve mysteries by exposing seemingly otherworldly ghosts and monsters as non-supernatural criminals.

Hanna-Barbera and its successor Warner Bross Animationhave produced numerous follow-up and spin-off animated series and several related works, including television specials and telefilms, a line of direct to video films, and two Warner Bross-produced feature films. Some versions of Scooby-Doo feature different variations on the show's supernatural theme, and include characters such as Scooby's cousin Scooby-Dum and nephew Scraapy-Doo in addition to or instead of some of the original characters.
