December 23, 1947 - Walter Brattain and John Bardeen of Bell Labs, under the direction of William B. Shockley, demonstrated the world's first transistor.
The point-contact transistor was made of two gold foil contacts sitting on a germanium crystal.
The New York Herald Tribune predicted that this invention would be a revolution in the electronics industry.
78 years later, we have chips with over 200 billion transistors and over 1.3E+23 transistors built to date.
