Geeze, you kids make me feel old.... In the mid-90's, I had a 133MHz Pentium PC with a 1.2GB HDD, 16MB of RAM, and a 28.8k modem. You could find people using 14.4k or even 9600 baud modems. Some folks had T-1 lines, but those were pretty expensive. AOL was still king, and AOL had a lot of not-so-savvy people thinking that they were the Internet. There were a lot of sites for setting up personal homepages (Geocities being one of the bigger ones). There were still a lot of ads, but very few were animated. I'm not including flashing or blinking; there was a lot of that. Downloading was difficult; the modem connections would often drop for no apparent reason. It took about an hour to download a 1 MB file on a 28.8 modem. I don't think YouTube (and Flash in general) took off until after the 56k modems were introduced. CSS was a major innovation when it hit. There were a lot of message boards. There was some online gaming; I mostly remember Warcraft, C&C, and Diablo. I know some of the early shooters were network capable, but I never got into those. Ultima Online was the granddaddy MMORPG.
The premier browser was Netscape. Microsoft had to play catch-up with Internet Explorer, and they bundled it with Windows as part of their plan. They got in a fair amount of trouble for that, but they did manage to kill off Netscape eventually. IE was free with Windows, and Netscape was sold separately for around $35. IIRC, the code for Netscape eventually formed the core for Firefox after Netscape (the company) became defunct.
