This book describes the stage-by-stage creation and development, from the mid-nineteenth century to the present day, of the remarkable global communications technologies that have profoundly transformed the way that people live and work.

Written in a highly readable style, this book provides a fascinating account of the key innovators from Faraday, Maxwell and Hertz to the inventors of the transistor, microchip, optical fibre systems and the World Wide Web. The book explores the background and motivation of these pioneers and the social and economic environment in which they worked. The significance of each innovative step is shown in terms of the impact - in scale and relevance - on today's communications world. John Bray also looks to the future for innovations yet to come.

This book will be interest to all those interested in the human thread running through the history of technological advances in telecommunications and broadcasting.
