the character. Scooby-Doo, Where Are You! premiered on CBS on September 13, 1969, at 10:30 a.m. Eastern Time. It ran for two seasons, with a total of 25 episodes. Its final first-run episode aired on October 31, 1970. Personality In most incarnations of the series, Scooby is regarded as a unique Great Dane dog who is able to speak in broken English, and usually puts the letter "R" in front of words and noises made. Other incarnations, such as A Pup Named Scooby-Doo, present him as a speech-impaired dog in the larger fictional universe as nobody in Coolsville seems bothered by his speaking ability. In recent years (most notably in Scooby-Doo! Mystery Incorporated), Scooby is able to speak in complete sentences and has more dialogue, though partially retaining his speech impediment. He consistently shows about the same level of intelligence as his friends, while also being subject to the same knack for clumsiness and moments of being dimwitted as well. Different iterations of the character have been developed and expanded in the various series featuring the characters, many of them contradicting, such as the original series and the recent live-action films where Shaggy and Scooby first meet as older teenagers for the first time. This contradicts the animated series A Pup Named Scooby-Doo, where they know each other from almost infancy, though the films may be seen as having a different continuity altogether than the cartoon products. As an adult canine, Scooby is usually treated as a mix of a pet and a friend by his companions. In all versions of the character, Scooby and Shaggy share several personality traits, mostly being cowardly and perpetually hungry. Yet their friends (Fred, Daphne, and Velma) encourage them to go after the costumed villains, usually with "Scooby Snacks". The biscuit-like dog treat or cookie snack is usually shaped like a bone or, in later versions of the cartoons, Scooby's dog tag. However, Scooby's inherent loyalty and courage do often force him to take a more heroic stance even without any prodding. Scooby is also extremely ticklish, and this is seen in many of the television series and films. Scooby has a speech impediment and tends to pronounce most words as if they begin with an "R"; however, most characters are able to understand him almost perfectly. In most iterations, he keeps his sentences relatively short, usually using charades for anything longer than three
