Scooby-Doo

Scooby-Doo! is a 2D animated series produced for Saturday morning television in several different versions from 1969 to the present. The original series, Scooby-Doo, Where Are You!, was created for Hanna-Barbera Productions by writers Joe Ruby and Ken Spears, CBS executive Fred Silverman, and character designer Iwao Takamoto. Hanna-Barbera produced numerous spin-offs and related works until being absorbed in 2001 into Warner Bros. Animation, which has handled production since then. All versions of the show feature a talking dog named Scooby Doo; the original series included four teenagers or young adults: Fred "Freddie" Jones, Daphne Blake, Velma Dinkley, and Shaggy Rogers. These five characters (officially collectively known as "Mystery, Inc.", but never referred to as such in the original series) drive around in the Mystery Machine van, solving mysteries by exposing seemingly otherworldly ghosts and monsters as flesh and blood crooks. Later versions of Scooby-Doo featured 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.
