David Gardner: Quote No.4. This one comes from one of my favorite recent television shows. The show is slightly off-color. The quote is, too. I hope you'll forgive me. But if you've never seen The IT Crowd -- which is a British sitcom centering on two guys who are running the IT department at a nameless, faceless corporation, and the antics that they go through trying to help other people who are clueless with their computers -- I would highly recommend you try to watch a couple of clips at least on the Internet, because you'll see The IT Crowd clips out there.

It's kind of a great buddy comedy with Roy and Moss, but in one particular episode, Moss is the ultimate geeky character. This is a show, by the way, which celebrates geek culture. Before I explain much more about just the nature of geekiness, let me just give this quote, which is from Moss, played by the wonderful British comic actor Richard Ayoade. Moss's line -- and I'll explain a little bit more in just a sec -- is this:

I came here to drink milk and kick ass, and I've just finished my milk.

What I love about that quote is not only that it's just funny on its own -- he is actually in a situation where he is going to try to kick some ass, but he's drinking milk, because that's just part of who he is -- but I want to opine about the nature of geekiness. This show is a geeky show, and a book that I recommended to some of you on this podcast which you've enjoyed -- you told me that online a few months ago -- is Ready Player One. That's a very geeky book, as well.

But my observation about geekiness is this: It grows less geeky and increasingly mainstream over time. Back when I first read The Lord of the Rings somewhere in the 1980s -- I know some of you read it in the 1970s and 1960s -- that was really pretty geeky stuff back then.

Then it became a multibillion-dollar movie franchise on top of all those books and all the history there. Or how about Star Trek? Or Star Wars? These are incredibly geeky franchises. They started with small splinter groups of fanatically geeky people who loved them, and yet now, they all end up being, again, multibillion-dollar franchises that run transmedia. It might be a lunchbox, it might be a movie, and everything in between.

So I think part of the nature of things like Ready Player One -- which, by the way, is about to go mainstream, itself, and Steven Spielberg is making it into a movie as we speak -- is that I think what's really at the heart of this is that people seriously love these characters, or situations, or stories. And it's really the fanatical affection -- even if it starts as a small group of people -- that really burns bright and can burn for a long, long time.

And especially I think people often associate geeky with fantastical things -- sci-fi, or swords-and-sorcery fantasy -- things that are not part of the here and now and the everyday. And so when you combine those two things -- a fantastical thing and potentially a very geeky initial readership, or listenership, or audience -- you have the stuff that makes, well, Harry Potter.
