The past century has seen developments in communications technology probably unrivalled in any other field of human activity. Significant advances are made every year, and both our work and leisure activities are critically influenced by these developments. Getting the message explores the fascinating history of communications, starting with ancient civilisations, the Greeks and Romans, then leading through the development of the electric telegraph, and up to the present day with email and cellular phones. The technology is explained in a particularly simple and accessible way, and themes from politics, economics, and society weave in and out of the scientific ideas. The book concludes with a look at the possible future of communications, the new developments to come, and the implications these will have for our everyday lives. Lavishly illustrated, and including many original illustrations that show just how these new developments were received in their time, the book presents an informative and highly entertaining introduction to the field of communications.
