I first had access to the internet in 1995, but it was on someone else's dial up connection and I only went on for a couple minutes, knew nothing about it and found it pretty stupid as the connection was so slow, it was about worthless. Then in 1997 I actually started using it (still slow dial up). I remember in the Spring of '97 buying a book (magazine?) at the book store with a list of websites that were available broken down into categories.....for some reason, I wanna say Shaq was on the cover of this magazine. Not that it had every website in the world listed on it, but was probably a decent % I would think....imagine the size of that magazine today?!
I was studying computer science at a university in the 80's, at that time the internet existed - but primarily for email and that was primarily across education institutions. You could send email to students/profs around the world at other universities that had email servers. You could also read/post to Usenet news groups, which was a precursor to a forum like this, albeit text only, and with little or no moderation: https://en.wikipedia.org/wiki/Usenet
