Something that comes up a lot online is the idea of how much of Doctor Who you have to have engaged with (or have recall of) to legitimately call yourself a fan. Now, my view is that there isn’t a minimum or maximum level. I am not interested in being the keeper at that gate. And while I cannot personally imagine ever not wanting to watch all television Doctor Who, I don’t think that a fan of the twenty first century show who hasn’t got round to The Faceless Ones Episode 3 is some sort of fake fan casual whose views on The Reality War are thus null and void. 

Nevertheless, I also can’t imagine personally being a Big Finish audio drama completist. That’s partially, but not entirely, because there’s so much of it I’m not sure it’s an affordable hobby even if I had the time. Which I don’t. That’s also despite me being of an age to be a fan when they started, and thus I could theoretically have followed them month to month. But even then it wasn’t a priority as an affordable hobby for 1999 me, even if I’d had the time. (Which, if I’m honest, I did.) I have bought and heard many of them. Probably more than there are twentieth century TV stories. But it’s still a very small percentage of the vast whole and I wouldn’t know where to start a tidying up exercise now.

Of course, it’s arguable that there are different BF ranges for different sub audiences within Doctor Who fandom. Those aforementioned fans of just the twenty first century show who haven’t got round to The Faceless Ones Episode 3 are even less likely to want an audiobook featuring two of its now octogenarian cast. I assume. People who hate the concept of pre-Hartnell Doctors are unlikely to shell out for the Fugitive Doctor box sets. (Although there will be inevitably be exceptions in both cases.) That makes sense; but it just underlines the idea that Doctor Who is undergoing its own smaller version of the siloing of media we see across the west, or at least in English speaking culture. (I feel less qualified to comment on any other.)
