I was around 13 or 14 years old, so it was 1996/1997. Because of school, I was using the Internet more often, which translated to me using it more at home. I didn't really get heavy into it until I was fifteen, after Titanic came out.
Back then I used it for chat rooms (horrible, horrible idea), and Teen People.com. I mainly used the computer for games, but the Internet games were slow and boring in the late 90s.
Now I use to keep in touch with friends, view videos, and pretty much everything I would have found out through newspapers, and TV.
