I know that several years ago now already there were some people who would proudly say they "don't watch TV" only to reveal that they did sometimes watch movies or even TV shows on DVD. They'd say it as if somehow that was different and special or something, not just watching whatever was on or whatnot.

I think most people these days say "TV" when they mean television shows no matter how they watch them (streaming, DVD, broadcast, on a DVR, whatever), but the lines really do continue to blur.
