There were these thigns called 'modems'. They were acoustically coupled at up to 300 baud! You took your phone off the hook and put it on this modem thing and your computer would call a phone number for you and letters would flow though the phone. Sometimes they got stuck. But a lot of times, you got the letters to form into a screen. Sometimes in color, but you had to have one of those nifty 4 color monitors.
You could communicate with a ton of people at a time, if the sysop was good, maybe even up to 16 :gasp;. there were games that were made from letters. And p0rn made from letters because you could never get enough porn.
That way was good for a long time. At one point you stopped needing to put the phone on top of the modem and speeds quadrupeled to 1200 baud. 1.2kbps. It was godlike!
then, gopher came along. You could see exactly one site, the Smithsonian museum and you could see a few real pictures of rocks and some dinosauts when the site was up, and it usually was not. But wow, real pictures. Joygasm!
Then came WWW. And it was good. Someone figured out people would pay for p0rn and then everyone needed a bigger pipe; a common lament among the geeky. some called them tubes. A series of tubes. The tubes got bigger till you could drive a car through them. Then a bus, then an airplane. Somewhere in there, along '98 or so, some guy made a computer site. The site had a forum. the conversations were about butter mostly.
