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 brown Great Dane named Scooby-Doo, who solve mysteries involving supposedly supernatural creatures through a series of antics and missteps.

Scooby-Doo! Mystery Incorporated (also known as Mystery Incorporated or Scooby-Doo! Mystery, Inc.) is the eleventh incarnation of Hanna-Barbera's Scooby-Doo animated series, and the first incarnation not to be first-run on Saturday mornings. The series is produced by Warner Bros. Animation and Cartoon Network and premiered in the United States on Cartoon Network on April 5, 2010, with the next twelve episodes continuing, and the first episode re-airing, on July 12, 2010. The series concluded on April 5, 2013 with two seasons and fifty-two episodes, with a total of twenty-six episodes per season. By episode count, this is the longest running Scooby-Doo series to date.
