20 year long patents are a large factor for it, designed for a very different world where progress was extremely slow. It's borderline absurd to keep them going today, they can restrict the usage of a technology for more than the entire duration of its usefulness before it's superseded by something better, which is patented again, giving you a series of sequential monopolies instead of a competitive market. I'm glad that at least the Chinese dgaf about patents so there is still some competition in practice even if questionably legal.

The other large factor is copyright. If we had 21 year copyright terms for shows and movies, I'd imagine someone would have set up a streaming service with every show and movie under the sun that they could fit into that, and people would eat it up, since they often just want to half-watch Seinfield, Friends, Star Trek, et cetera, since its their comfort show. A service that can provide that without being hostile is quite a lot of what many people look for in a streaming service.
