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 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 named Scooby-Doo, who solve mysteries involving supposedly supernatural creatures through a series of antics and missteps, while traveling using a brightly colored van called the "Mystery Machine". The franchise has several live-action films and shows.
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 until 1991. Two Scooby-Doo reboots aired as part of Kids' WB on The WB and its successor The CW from 2002 until 2008. Further reboots were produced for Cartoon Network beginning in 2010 and continuing through 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.
