This wasn’t technically my introduction to Who; I’m pretty sure I had seen some Tom Baker/Fourth Doctor repeats as a small child and I had a figurine of that version. But this was my first time new series were in production during my lifetime and my first time watching at an age where I could form memories.
This is more or less me, as well. I have very fuzzy memories of Classic Who reruns, but really jumped in with the 2005 series (although even then I started in 2007 or so). I have gone back and watched some Classic serials here and there, but my knowledge is far from complete.
It looks like they've been quite the global football.
