As a kid I interned at a bookstore, and before closing we'd write the book orders on a sheet of paper, slide it into the Fax machine to send to the book wholesale. I think the Fax printed out some kind of response a minute later.

Next day, the books would arrive. This was maybe 1996, but I thought it was pretty cool.

Fax was mind blowingly cool.

Maybe you can relate to seeing webcams or Facetime when it came out or something.

Being able to see a signed document or a picture someone took 5000km away quickly was mind boggling in its age.
