misteryo: The old media was doomed to be lost until digital distribution came along. Ancient hardware will fail eventually, too.
teceem: Not available to new customers you mean - that's not the same as "lost". Making backups has always been possible.
And there are emulators for ancient hardware, VMs, or backward compatible OS software running on new hardware.
misteryo: The rise of Netflix did not spell the end of people buying even physical DVDs and BluRays.
teceem: The rise of email didn't stop people from writing letters (pen&paper). When did you last get one?
Do all (video) media get a physical release these days? And if not, do you think there'll be more or less in the future?
It's hard not to see a certain precedent repeated in the future. The PC physical releases (and far from all games get them) have been very minimal in the last decade. Very few games get anything more than a standard DVD box, most of those don't even contain any printed booklets anymore. Codes in a box are often replacing the discs.
Ok, this transition even started before Steam - but I'm sure the rise of digital distribution only made it worse.
I'm glad the internet made niche markets viable - but I'm not going to pretend that things'll always stay the same.
I think you misunderstand me a bit.
Ancient media will fail. It happened (and is still happening) with film. It has happened to a big extent with video tape. It is happening with Digital Audio Tape (DAT). Old cds are losing their data. Governments and militaries can't transfer their old archives to new technologies fast enough, and ancient papers in files crumble with age, get destroyed in a flood, get lost or mislabeled...
I'm not saying it's a good thing, just that it is fact. And it's not as bad as some people make it out to be. We lost the library at Alexandria, and that's too bad. But we produce new stuff at a far greater rate than we can store up the old. It's kind of a shame, but not really.
So, losing old media because of new technology and new markets is nothing new.
Also, to email-snail mail: Snail mail does still exist and will continue to, because it has some qualities that email lacks. It's more of a niche market, but it won't die out. Likewise, physical copies of games with manuals, maps, etc., have become a niche market. So has vinyl records. Cassette tapes are currently trying to make a niche comeback.
BUT, there is still no indication that the rise of subscriptions will do the same to buying a digital library of games. They both seem to be able to exist in a growing market space.
We shall see.
