There was no need for a shoulder bag or a Wi-Fi connection in a hotel room. John Bardeen, Walter Brattain, and William Shockley spent years of research to finally develop a working point-contact transistor. By modern standards, tube-based computers were slow and enormously bulky. At long last, in December of 1947, three physicists from Bell Laboratories successfully invented the first working transistor. In fact, the term bug was coined when moths or other insects would light on the tubes and blow them out, according to Mike Feibus, an analyst at TechKnowledge Strategies Inc. It wasn't a very efficient technology, and required a lot of tubes and bulbs and heat to do basic mathematically calculations. The tube would be turned off for a zero, and on for a one. It's probably doubled from what it would have been without transistors."īefore transistors, vacuum tubes were turned on or off to represent zeros and ones. Look at the change in the productivity of the whole economy. Look at transportation, computers, government, finance, manufacturing. "The invention of the transistor was probably the most important invention in the 20th century," said Risto Puhakka, president of VLSI Research Inc. That 10,000 times the number of ants on Earth.
