Welcome to BF, but Q factor has been a known thing for quite a while. I'm pretty sure I'd seen the term used back into my younger days without internet in the 70's and before.
I agree, the term is pretty old. I don't know when I first heard or saw it, but I think it was in the first half of the 1970s.
