When and why did the term "Era" come about when referring to Vanilla Classic?

iirc blizzard themselves termed the forever vanilla realms the classic era realms

Yeah, I mean look at all the sticked threads that say Era, this is a Blizzard term first.

Anyway, I don’t even suspect this is even an actual question. I’m probably not going to bite on any more of this OPs threads. I think I know who they are.
