Film theory once again underwent re-thinking in the 1990s with the introduction of digital imaging. It discussed how this revolution would have an impact on the filmmaking industry and thus film theory. There was a proliferation of new theories, among them one which theorists called "the gaze." It refers to the way the audience views and looks at the film. With the new technology everything became more "real" and the audiences saw things differently. Film theorists began revisiting old films and began analyzing them to see how "the gaze" affected them.
