.hack (pronounced "dot-hack") is a Japanese multimedia franchise that encompasses two projects; Project .hack and .hack Conglomerate. Both projects were primarily created/developed by CyberConnect2, and published by Bandai. The series franchise revolves around an alternative history setting in the rise of the new millennium regarding the technological rise of a new version of the internet following a major global computer network disaster in the year 2005, and the mysterious events regarding the wildly popular in-universe MMORPG series The World. The series is mainly followed through anime and video game installations, and has been adapted through manga, novels and other related media.
Project .hack was the first project of the .hack series. It launched in 2002 with the anime series .hack//Sign in April 2002 and the PlayStation 2 game .hack//Infection in June 2002. Project developers included Koichi Mashimo (Bee Train), Kazunori Ito (Catfish), and Yoshiyuki Sadamoto, (Gainax). Since then, Project .hack has spanned television, video games, manga, and novels. Project .hack centers mainly on the events and affairs of the prime installment of The World.
