The two groups and the Madison Academics’ Gaming Enthusiast Society were planning the convention by March 2007. Geek.Kon was first held began in October 2007 at the University of Wisconsin–Madison's George L. Mosse Humanities Building as a two day free convention. Expecting hundreds, it received over 1800 attendees. In 2008, the convention expanded to include one of the upper floors of nearby Vilas Hall.
