Small to medium.

I'm either too lazy to count ours or too afraid, but I'm sure it's much larger than that.

Although it also depends on how many videotapes that is on top of.

Supergee is not one for watching movies or TV in general; over the years, people (mostly Womzilla & I) have bought him some of his favorite movies on DVD, but that's not much. And none of the TV shows--boxed sets of an entire run of a TV show take up a lot of space.

We've just bought a big-ass (50") TV and will set it up to stream Netflix; we'll see if the latter makes us less likely to buy/keep DVDs.

I think we have roughly 100, and (1) I didn't have any DVDs when I moved here (1998 -- they were available, but not yet the primary format) and (2) neither of us is terribly fond of TV/movies. So yeah, small.

I recuse myself as I note that my sense of books vs. other media varies widely, and that having been in a severely ascetic environment (being a liveaboard on a boat) has warped my ideas further.
