In 1996, 15-year-old Eric Harris created a private website on America Online (AOL). It was initially to host levels (WADs) Harris created for use in the first-person shooter video games "Doom" and "Doom II", as well as "Quake". On the site, Harris began a blog, which included jokes and his thoughts on his family, friends and school. It also detailed Harris sneaking out of the house to cause mischief and vandalism, such as lighting fireworks, with his friend Dylan Klebold and others.
