Throughout the history of cinema, a radical avant-garde has existed on the fringes of the film industry. A great deal of research has focused on the pre- and early history of cinema, but there has been little speculation about a future cinema incorporating new electronic media. Electronic media have not only fundamentally transformed cinema but have altered its role as a witness to reality by rendering "realities" not necessarily linked to documentation, by engineering environments that incorporate audiences as participants, and by creating event-worlds that mix realities and narratives in forms not possible in traditional cinema.
