For a society to be considered truly democratic, there should be a high degree of protection accorded to the expression of ideas in published form, whether the medium is newspapers, magazines, books, pamphlets, motion pictures, television or, most recently, the Internet.

Of course, these experiences are unique to the culture and history of the United States, but the general principles they elucidate have wide applications in other democratic societies.
