Communication and Information

Show Summary Details

Preview

A rapid succession of technical advances laid the foundations for massive dissemination of information and created new forms of communication. The former innovations included automated typesetting (linotypes) and typewriting, chemical processes for papermaking based on wood pulp, affordable photographic cameras, convenient films, movies, and sound recordings. New means of communication included telephones and the epochal discovery of Hertzian waves that were soon used for the first wireless broadcasts and later developed into the still expanding universe of electronic devices.
