It is true that electronics developed from the study of electricity. Early ideas about the way electric 1 could flow through conductors and through a vacuum led to the development of useful radio 2 and telephones. It was possible to send messages round the 3 with what was, by today’s standards, incredibly simple and crude equipment.

The Second World War provided an urgent requirement for more sophisticated communication and other electronic systems. The 4 of radar required a big step forward in theory and an 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 5_ .

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 6 . In some branches of industry electronic systems were regarded as useful, but 7 systems not directly concerned with wireless or television were still unusual.

Only in that early 1960s did electronics 8 early ‘came of age’, thanks to the work of three scientists working in the Bell Laboratories in the USA: Bardeen, Brattain and Shockley. In 1957 they assembled the first working transistor.
