I’m a day late on this but April 7th, 1969 was the day that the first Request for Comment was filed. RFCs are the governing documents on how the Internet is supposed to run. Companies like GoDaddy and Microsoft don’t follow them that often but they’re supposed to. As I read RFC #1, it was about how data is supposed to be transfered from one computer to another.
Spam came later. 🙂
