1991, 9600 baud dial up in dos.. those were the days!
it was just BBS' but some of them had usenet access, archie, gopher, ftp, text www, etc.
graphic web didn't exist until about 1993, everything before then was text based browsing, mostly universities and military/government sites
first web browsers (visual) were mosaic, netscape navigator, the text based ones were lynx and a slew of others.
