Disc media is probably on its way out, in general people stopped using discs for music ages ago and using them for movies and PC software has also started to fizzle out.
Games will be next.
Your kids will laugh at you when you tell them you used to play video games on plate sized shiny discs.
That's a bit misleading as all album sales are declining in favor of streaming
Yet about 80 million CD sales in the US last year, that's not stopped using discs ages ago.
It's more fair to say people stop caring about actually owning music, movies and next games. Streaming is the future :( Ownership is on its way out.
Btw my kids play video games on discs!
