I've just been reading an article in the Irish Times about cartoons:
"Which brings us neatly to the 50th anniversary of Scooby-Doo, Where Are You! The Hanna-Barbera show was conceived to fill a gap after Action for Children’s Television (ACT), one of those endless busy-body organisations concerned with filth on telly, forced the cancellation on US TV of several cartoons deemed too violent. ACT had, in the era of the Altamont rock festival, no problem with a bunch of young weirdos travelling the country in a brightly coloured van.
Fred (cravat), Daphne (damsel in distress) and Velma (intellectual with Agnes Varda’s haircut) bounced off outer levels of the counterculture. But Shaggy and Scooby were something else. Voiced by popular DJ Casey Kasem, Shaggy spoke in, like, the unmistakable patois of the dope fiend, man, and moved with a lobotomised languor that suggested he should stay away from heavy machinery. Both he and Scooby, apparently a great Dane, were always hungry. It’s almost as if they were in the grip of something the uninformed ACT wouldn’t balk at hearing described as “the munchies”."
Apparently the creators were appalled at such a suggestion
