I've been online since... The early 90s, about 1994 or 1995.
Playing Descent, Quake and Doom at school with friends via LAN, looking up information on shows, printing off fanfiction (didn't know what the term was at the time) to read later, looking up information on how to find all the items on various video games, information on movies, video games that were coming out, email, chatting with complete strangers.
Remembering how Geocities was the awesome webhosting website, the dotcom boom of 1996-1997.
Um, one of the first things that the internet was used for was creating chat rooms for people to chat and discuss things with each other, followed by fanfiction and gamefaqs.
Movies and music came along much, MUCH later than that, mostly due to technical restraints.
In fact, if not for the internet, I guarantee you that anime would not be anywhere near as popular in the West as it is today. Nevermind such anime like One Piece, while absolutely huge in Japan, it has a far more modest following in the West (still big though), however, most people wouldn't bother with it outside of Japan if not for the internet scanning the manga and posting it up online.
