The introduction of the semi-conductor or transistor. This did away with the valve or the American `Tube` which needed a high voltage to function the voltage being drawn from a bulky and heavy battery. As you are aware nowadays the transistor which has now been integrated into a `Chip` is powered by a small battery. I would suggest further `Web` research for more in depth information.
