>So a lot of people just stuck with H.264 as the "good enough" codec as a result. The only people not using it were organizations who couldn't or wouldn't pay for any patented invention (e.g. most of the web standards people, Wikimedia, etc), who stuck with Theora and later VP8.

h.265 is very popular in the piracy scene, since you can get a file size about half that needed for equivalent-quality h.264. Of course, being pirates, they don't worry about patents. And since decoders are freely downloadable for players like VLC, there's no good reason not to use it.
