It is true that electronics developed from the study of electricity. Early ideas about the way electric current could flow through conductors and through a vacuum led to the development of useful radio systems and telephones. It was possible to send messages with what was, by today's standards, incredibly simple and crude equipment.

The invention of radar required a big step forward in theory and even bigger step forward in engineering. The study of electronics gradually became an important study in its own right, and the radio engineer became a specialized technician The post-war development of television led to one of the most massive social changes that have ever taken place: many households became the owners of televisions, as well as radios and record players.
