Do you still buy movies physically?

[Barozi]

The difference is that people can use DVDs in modern devices which wasn't possible for VHS when DVD players came out (there are hybrid players of course but naturally more expensive). Also the discs are cheaper than BluRays and there are still quite a lot of older TV series and movies that never saw a BluRay release. People probably wouldn't buy those to experience better audio and visual quality (depends on how they were filmed) but some would maybe consider getting a 3-disc BluRay boxset of a series instead of a 30-disc DVD boxset.

It's crazy when you think about it. A series as recent and successful as How I Met Your Mother doesn't have a Blu Ray boxset, only DVD. In fact, the only season that was released on Blu Ray was Season 4. Despite the fact that the majority of seasons (maybe even all of them?) were shot in HD, so there's no reason not to release them on BluRay. Two and a Half Men would be another example....
