[RetroTechie]

Same. When I was born, optical storage did not exist in any form. It was vinyl, cassette tapes & floppy disks. Lasers were SoTA things that scientists worked with. Not in consumers' hands.

Then (besides LD & VHS) came the CD, which has gone a bit out of fashion lately.

Then the DVD. Which was popular in its heyday, but also over the hill.

Then Blu-Ray. Not to mention a truckload of recordable & rewrite formats, DVD-RAM, MO discs & what have you. On the computer side, flash & TB hdd's for cheap.

Disclaimer: and I'm not even that old yet! Neither retired or owner of a gray beard.
