Scooby-Doo is an American media franchise created by Joe Ruby and Ken Spears and produced by Hanna-Barbera.
It is the second-highest-rated American cartoon ever, second only to The Simpsons, with 30 seasons and more than 580 episodes. But with new seasons ordered it should soon be the oldest design and with the most seasons.
It has been screened in Brazil by TV Tupi, Rede Manchete, Rede Globo and is currently on SBT, Boomerang, Tooncast and Cartoon Network. In Portugal, the animation is shown by Cartoon Network.
Consisting of a group of four detainees Fred, Velma, Daphne, and Sausage, with a talking Great Dane named Scooby-Doo, who travels in a van called the Mystery Machine, and help investigate mysterious cases. They visit inhospitable places, haunted houses, abandoned parks, swamps, and islands, most often threatened by monsters, zombies, villains, but considering the episodes, they are often referred to as “ghosts,” even if they are not.
Detectives follow clues, flee the villains, and often find themselves lost in mazes, secret passageways, and dark basements. They always split into two groups when they go looking for clues: Fred and Daphne go for one, while Sausage and Scooby accompany Velma, who, despite his cleverness and intelligence, keeps losing his glasses and getting into the trouble of Sausage and Scooby.\
The formula of the episodes is always the same, but that doesn’t detract from the show’s glow: after a chase scene or a musical sequence, and through some mind-boggling plan or idea, villains are always caught. They are always masked and true identities are revealed as they remove their masks. Behind them is always the face of some character already known in the story. Each time they are unmasked, the villains always say, “I would have made it if it wasn’t for those gutted boys and this stupid dog.” This slogan (the translation for the voice acting almost always changes the words) is part of almost all the drawings and films made.
