At the moment the catch word "interactivity" is common talk. Most often it is mentioned in connection with a revolution in television. Techno-prophets anticipate more than 200 TV channels for the near future in each home. Thus, viewers will not only be able to choose from an almost unlimited offer, they will also be able to determine the course and outcome of individual programs.
Proponents of these new opportunities are already praising interactivity as a means to change the passive reception of the viewer into an active one. Thus, it seems as if Bertolt Brecht's Radio Theory , which he developed in the late twenties, is now to become reality. Brecht envisioned the transformation of broadcasting from a distribution machine into a communication device that offers listeners the opportunity to help create its content.
And actually this development has been actively persued for years by groups such as the Ponton Media Art Lab, by persons such as Myron Krueger, and by the communication structure of the internet.
