Abstract
The first part of this chapter is essentially all about one technology, the use of electromagnetic waves for audio communication (radio), followed by visual communication (TV). Color TV followed black-and-white TV in the early postwar period. Mobile video technology was a child of the mobile phone and TV, triggered by data compression. Mobile smartphones with cameras are now ubiquitous, as is the huge modern computer gaming industry. Display technology has also changed dramatically, primarily thanks to the invention of liquid-crystal displays and light-emitting diodes (LEDs).
