I've bought a ton of movies in the past. The vast majority I've sold second hand or thrown away because I just didn't care to watch again and I didn't feel like storing something I'd never use forever.

Same goes for a lot of other media. Some amount of it I'll want to keep but most is practically disposable to me. Even most videogames.

No, I do own some (actually it was more in the VHS days so tapes) and I just found that I never really watched them again. So I stopped buying movies. I'm the same with books. Once I read it, I've read it. I would rarely read a novel twice. I know what's going to happen, so what's the point? Reference books are different of course.
