Tl;dr; 20 years is a life time
I still think back to those days in 1983, when fighting my mum over access to the TV. I swear, she never cared watching TV before, until I got that Commodore 64 and didn't have my own screen (yet)
It was the fight of the titans, seeing who was the most stubborn
In the end, I made enough money to buy a 12" black and white TV to put up in my own room. Peace settled over the land and everyone could back to worry about total nuclear war (the real thing, not the later video game)
But it's been a long journey, technologies come and go, concepts come and go, target audiences come and go. VHS won out over Beta MAX, but nobody today knows what the heck either of them are. Tapes were the original medium video games were sold on for home computers, whether they be Acorn BBC model B or Sinclair ZX Spectrums. Floppy disks followed and less floppy, floppy (3.5") followed and eventually cd roms. Even those eventually died out and everyone gets their fix from the internet. Scratching my head and wondering what replaces the current internet some day? All of that in 2x20 years.
