Scooby-Doo is an American animated cartoon franchise, comprising several animated television series 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 four teenagers—Fred Jones, Daphne Blake, Velma Dinkley, and Norville "Shaggy" Rogers— and their talking Great Dane dog named Scooby-Doo, who solve mysteries involving supposedly supernatural creatures through a series of antics and missteps.^[1]
Following the success of the original series, Hanna Barbera and its successor Warner Bros. Animation have 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 Bros.–produced theatrical 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 Scrappy-Doo in addition to or instead of some of the original characters.

Scooby-Doo was originally broadcast on CBS from 1969 to 1976, when it moved to ABC. ABC aired the show until canceling it in 1986, and presented a spin-off featuring the characters as children, A Pup Named Scooby-Doo, from 1988 until 1991. The original series format was revived and updated for The WB Network's Kids' WB programming block as What's New, Scooby-Doo, which ran from 2002 to 2006. Another Scooby series, Shaggy & Scooby-Doo Get a Clue!, aired on the The CW network from 2006 until 2008. The current Scooby-Doo series, Scooby-Doo! Mystery Incorporated, premiered on Cartoon Network in April 2010.^[2] Repeats of the series are broadcasted frequently on Cartoon Network and Boomerang in the United States and other countries.
