As older forms of media such as film and video converge with new digital technologies and networked communications, we are challenged to expand and redefine our critical understanding of the media and its intersection with the social, cultural, and educational institutions in the 21st century. In 1983, the Walker Art Center hosted Media Arts in Transition, a major national conference focusing on the emerging forms of independent film and video production. The conference examined the technological, social, economic, and aesthetic forces shaping the future of the media arts. Many of the questions posed at the 1983 conference remain relevant today, but their contexts and implications are far broader. Sins of Change: Media Arts in Transition, Again unites curators, academics, and artists from around the world who share their perspectives on the issues underlying the state of media arts in transition, again. Events take place at the Walker Art Center, Minneapolis, unless otherwise noted. Media Arts in Transition, Again is copresented by the Walker Art Center and The Kitchen with support from the Ford Foundation. Major funding for this program has been provided by The Bush Foundation and Northwest Airlines, Inc.
