Communications: An international history of the formative years traces the evolution of communications from 500 BC, when fire beacons were used for signalling, to the 1940s, when high definition television systems were developed for the entertainment, education and enlightenment of society. The book does not simply provide a chronicle of dates and events, nor is it a descriptive catalogue of devices and systems. Rather, it discusses the essential factors - technical, political, social, economic and general - that enabled the evolution of modern communications. The author has taken a contextual approach to show the influence of one discipline upon another, and the unfolding story has been widely illustrated with contemporary quotations, allowing the progress of communications to be seen from the perspective of the times and not from the standpoint of a later generation.

The Struggle for Unity: Colour television, the formative years traces the evolution of colour television from 1928, when rudimentary colour television was demonstrated for the first time, to c.1966, when the NTSC system and its variants, the PAL and SECAM systems, became widely available for the entertainment, education and enlightenment of society. Among the many topics discussed in the book, mention is made of the following: compatibility and non-compatibility; mechanical and all-electronic systems; field, line and dot sequential scanning; bandwidth constraints and band-sharing techniques; the CBS-RCA conflict; the relative merits of the different systems; the attempt to achieve unity of purpose in Europe; standards; and the development of colour cameras and display tubes. The book, which is based predominantly on written primary source material, does not simply provide a chronicle of dates and descriptions of events, devices and systems. Rather, it discusses the essential factors of colour television history from a general, technical and political viewpoint. Great care has been taken to ensure that an unbiased, accurate and balanced history has been written. Numerous references are given at the end of each chapter and the book is profusely illustrated.
