Might have been the late 90's. Home computers were still fairly rare in the mid 90's, dial up and all that stuff. I think I installed a home computer somewhere around '97 or '98? I was working at Tektronix at the time and in those days we had full access to the internet. Message boards, games, even porn. The sysadmins started to crack down somewhere after 2000. These days the employees at some of the places I worked can't log into message boards. And porn became an instant firing offense somewhere around 2005. They started walking people out the door for accessing porn on work computers.

I managed the data center for a few years at Xerox and it opened my eyes to privacy and security issues. Before I worked that job I really didn't understand that all digital content in a large corporation is captured, stored, reviewed, etc. I used to think that I just wrote stuff on my computer and sent emails to people and that it was all private. I quickly learned that nothing is private. Every transaction is recorded and stored, typically for 7 years. HR or Security can review anything and everything at any time. So around that time I stopped logging into message boards from work.
