ABSTRACT
As computers become the printing presses of the twenty-first cen tury, ink marks on paper will continue to be read, and broadcasts to be watched, but other new major media will evolve from what are now but the toys of computer hackers. Videodisks, integrated memories, and data bases will serve functions that books and libraries now serve, while information retrieval systems will serve for what magazines and news papers do now. Networks of satellites, optical fibers, and radio waves will serve the functions of the present-day postal system. Speech will not be free if these are not also free.
