I was just watching the documentary about the long ago startup, General Magic, when about halfway through, they show a sequence representing when the Internet entered public awareness. And what do they use to represent the pre-browser era, but the ZModem tool I wrote for Aladdin Systems when I was in grad school.
Ironically, I don't think it was widely used over the Internet, but was generally used for BBS downloads.
Something to proudly show the kids.
