The history of communications is extensive and this book explains how communications have evolved from the time of Aeschylus's Agamemnon (485BC) to circa 1940. It discusses the essential factors - technical, political, social, economic and general - which have enabled modern communications to evolve from early primitive stages of development. Considerable endeavour has been taken to present the views of scientists and engineers, newspaper reporters and editors, cartoonists and others so that the progress of communications is seen from the perspective of the times and not from the standpoint of a later generation.
