^Uh, yes, we all know that. That's why we've been tossing around the word "historical" in our posts as if we knew what it meant. The point is about whether the first serial fits that category or not.
And it does. There's no need to be pedantic about those terms, in my opinion. Or we could argue that, since they're all fictional anyway, there's no point in calling any of these stories "historical".
