fan fiction has become more popular and widespread since the advent of the world wide web. according to one estimate, fan fiction comprises one-third of all content about books on the web. in addition to traditional fanzines and conventions, usenet group electronic mailing lists were established for fan fiction as well as fan discussion. online, searchable fan fiction archives were also established. the online archives were initially non-commercial hand-tended and fandom, or topic, specific. these archives were followed by non-commercial automated databases. in 1998, the not-for-profit site fanfiction.net came online, which allowed anyone to upload content in any fandom. the ability to self-publish fan fiction at an easily accessible common archive that did not require insider knowledge to join, and the ability to review the stories directly on the site, became popular quite quickly.
