Scooby-Doo and Shaggy Rogers

Scooby-Doo (often written as Scooby-Doo!) is an American media franchise owned by Warner Bros. Entertainment and created in 1969 by writers Joe Ruby and Ken Spears through their animated series, Scooby-Doo, Where Are You!, for Hanna-Barbera, which was later absorbed into Warner Bros. Animation in 2001. The series features four teenagers: Fred Jones, Daphne Blake, Velma Dinkley, and Shaggy Rogers, and their talking Great Dane, Scooby-Doo, who solve mysteries involving supposedly supernatural creatures through a series of antics and missteps, while traveling in a brightly colored van called the Mystery Machine. The franchise has numerous shows, films, and specials.

Scooby-Doo was originally broadcast on CBS from 1969 to 1976, when it moved to ABC. ABC aired various versions of Scooby-Doo until canceling it in 1986, and presented a spin-off featuring the characters as children called A Pup Named Scooby-Doo from 1988 to 1991. Two Scooby-Doo reboots aired as part of Kids' WB on The WB and its successor The CW from 2002 to 2008. Further reboots aired on Cartoon Network from 2010 to 2018. Repeats of the various Scooby-Doo series are frequently broadcast on Cartoon Network's sister channel Boomerang in the United States and other countries. The most recent Scooby-Doo series, Scooby-Doo and Guess Who?, premiered on June 27, 2019, as an original series on Boomerang's streaming service and later HBO Max.

In 2013, TV Guide ranked Scooby-Doo the fifth-greatest TV cartoon of all time.

In 1968, parent-run organizations, particularly Action for Children's Television (ACT), began protesting what they perceived as excessive violence in Saturday-morning cartoons. Most of these shows were Hanna-Barbera action cartoons such as Space Ghost, The Herculoids, and Birdman and the Galaxy Trio, and virtually all of them were canceled by 1969 because of pressure from the parent groups. Members of these watch groups served as advisers to Hanna-Barbera and other animation studios to ensure that new programs would be safe for children.
