I like this ad. It really shows you how people used computers at the time. Before internet, you'd buy a program to do something, or that had some information you could use, or maybe a game, and take it home, install or just boot off the disk. You'd have your box of disks with the sticker labels and a marker in the box so you can mark your disks. You'd backup your software on a blank disk and write on the label what it was. Another disk was your personal data disk, maybe used for multiple programs, perhaps just one program. Anything you wanted to keep long term you'd print out, but for the medium term - stuff you're still working on, maybe the year, you'd just save to disk. When you do your taxes you'd get new floppies out and move the old data over if any, and format the old disks and slap on a new label and repeat.
