AltaVista
Back in 1996, whilst working in the IT Department of a company with around 100+ users, I was tasked with setting up the internet access on all the computers.
As we were still running Windows 3.1 at the time, this not only meant installing a TCP/IP stack and a web browser, but I also had to spend several minutes explaining what the internet was to each user after I had upgraded their PC. At that time this mostly consisted of showing them a few sites relevant to the business as well as introducing them to AltaVista. I would ask if they had any hobbies so that we could search on a topic in which they were interested. Most people would respond with topics such as gardening, knitting, tropical fish and so on, and I'd type that into AltaVista so that they understood how to get at the data they wanted.
After upgrading the PC of a user I will call Barry (mainly because that was his name) I asked about his hobbies and, with a large grin on his face, he replied, "Necrophilia." I shrugged and typed it into AltaVista. Now, given that this was only 1996, it was still amazing how many results were returned! It was a good job Barry had his own office so that no one else could see what we were looking at!
