I know its mostly supposed to be funny, but to be that guy...
The original development for SCOOBY-DOO, WHERE ARE YOU? was inspired by THE ARCHIES cartoon (where Archie, Reggie, Jughead, Betty, Veronica and Jughead's dog Hotdog are a band) crossed with the radio serial I LOVE A MYSTERY (where former WWII Pacific theater vetrans Jack Packard, Doc Long, Reggie York form a detective agency and travel the world to help people caught up in mysteries and intrigue).
The show at that time was called MYSTERIES FIVE and had 5 kids in the band (Mysteries Five) named Geoff, Mike, Kelly, Linda, and Linda's brother W.W. and a bongo playing dog named Too Much. Between gigs, the group would solve mysteries. This idea would be developed further to become SCOOBY DOO, WHERE ARE YOU, but would also be used for the most obvious Scooby-Doo clones:
Goober and the Ghost Chasers (like Scooby-Doo, but with less kids, Scooby could turn invisible, ghosts were real and would usually assist in helping against the fake ghosts + the Partridge Family. No the real ghosts didn't assist AGAINST the Partridge Family, the Partridge Family just showed up a lot) -
Clue Club (like Scooby Doo, but with two dogs helping solve crimes)
and The Funky Phantom (like Scooby-Doo, but the dog is a normal dog and they partner with the Ghost of a revolutionary war ghost to solve mysteries) -
But the Mysteries Five format is also the starting point for Hanna-Barbera's adaption of Josie and The Pussycats (the version where they tended to solve spy mysteries between gigs), Speed Buggy (three kids and their anthropomorphic buggy car stopped villains between races), Jabberjaws (where a band in the future stopped threats to their marine world with the help of their drum playing shark), and Inch High Private Eye (a tiny detective, his two friends and their dog stops criminals). Arguably Hanna-Barbera wouldn't have tried The Amazing Chan and the Chan Clan either, even if the source for the show pre-dates Scooby-Doo...
