Henry Jenkins is the Provost's Professor of Communication, Journalism, and Cinematic Arts at the University of Southern California. He arrived at USC in Fall 2009 after spending the past decade as the Director of the MIT Comparative Media Studies Program and the Peter de Florez Professor of Humanities. He is the author and/or editor of twelve books on various aspects of media and popular culture. He was one of the first media scholars to chart the changing role of the audience in an environment of increasingly pervasive digital content, and he has been at the forefront of understanding the effects of participatory media on society, politics and culture. His research gives key insights to the success of social-networking Web sites, networked computer games, online fan communities and other advocacy organizations, and emerging news media outlets.
