In the late 1980s I worked for a networking company that built processors and software for connecting terminals to mainframes (think old green-screen CRTs). At one point they were thinking about building products to connect with the fledgling internet and asked me to research the technology and write up an overview document on the architecture. I used telnet to log on to BBN servers and spent several weeks reading the RFCs for IP, TCP, SMTP, FTP, etc.
After I finished the overview document, they decided not to go forward with the project. About 1990 I went to another IT company and eventually got to work on some of that company's earliest web projects. Mosaic was the first browser I had any experience with, and I remember it was a big deal when inline graphics came along. Besides getting to work on an emerging technology, the best thing about being at that company was having access to a really fast network connection. At the time I could justify looking at web sites during work as important research.
