Clearly not always. Even when the show changed titles, it was clearly supposed to be the same series. So when was the first alternate continuity? A Pup Named Scooby Doo? Being a prequel makes it weird, but I think it's still intended to be just a prequel, not a reboot. Would the animated movies be a new continuity? And if so, which ones? The ones from the '80s, or just the series that started in the '90s, with Zombie Island? The tv series actually ended by that point, and this was essentially restarting it. But then are all those movies in that series one continuity? And what makes those a different continuity and not the same as the continuity they followed? I think it's still the same continuity as the original series. I mean, why wouldn't it be?
It would be easy to say the live action movies are a new continuity, especially because they largely reuse the plots of two of the then-recent animated movies, but then it's not like Scooby Doo has never done very similar plots before.
Would the first of the revived tv series be a new continuity? They were on at the same time that the animated movie series was still going, but obviously looked quite different. So would What's New Scooby Doo be the start of a new continuity? And would any of the later animated series also be new continuities, or could any be the same? And really, just because they might have different art styles, and even air at the same time as another series, doesn't mean they can't still be the same continuity.
Now, the live-action tv movies are again prequels, like A Pup Named Scooby Doo, so that seems to present a problem if you want to say those two things are the same continuity as each other. You could then take this to imply that the other live action movies are the same continuity as these ones, and there's a cartoon universe and a live action universe. But the live action movies also strongly present themselves as sequels to the tv series, so could just these prequel movies be their own universe? Or are the movies a universe where the original tv series was canon except for A Pup Named Scooby Doo?
Perhaps it's like Godzilla, where the original entry is always canon, and new continuities all count it. But where does the original entry end? It would be ridiculous to imply Scooby Doo Where Are You and The New Scooby Doo Movies different continuties. They're clearly supposed to be the same. And the same goes for the unbroken string of Scooby Doo tv series that would continue for the next 20 years. The only one that ever presents a problem is A Pup Named Scooby Doo, and that's only because of the live action tv movies, which suck even harder than the entry they contradict, which is what got the franchise cancelled in the first place. Both the animated movie series and the live action theatrical films treat the tv series as canon, and there's no reason given to disregard any particular part of it. So are they just alternate branches that both continue from the original tv series continuity?
tl;dr: Until some autist who has watched every episode of Scooby Doo ever made explains to me precisely where the cutoffs are for different continuities, and why these must be different continuities, I'm treating most series as being the same continuity. I know that probably doesn't work, but I want specifics.
