There you go with another anti-disc post.I actually think DVD is more likely to be the last physical format that survives. The numbers aren’t trending in a great direction for any disc format long term. DVD still has the largest consumer install base. For circumstances where streaming isn’t used, it’s more likely to be because someone never moved past DVD.
There is a small but relatively robust specialty market for DVD coming from places where picture quality isn’t a consideration and where streaming is not yet practical. For example, schools. It’s still easier in a lot of schools to wheel in a cart with a TV and DVD player to show something than it is to install WiFi and streaming boxes. People who check out physical media at public libraries statistically are much more likely to be watching on DVD.
DVD has value as a lowest common denominator and that’s what will likely keep it afloat as the last physical format. By the time we get there, they won’t be moving many units, but I think that’ll be the last one to go.
