VisiCalc, released in 1979.
The transistor, which revolutionized the computer industry, was invented in 1947 by John Bardeen, Walter Brattain, and William Shockley at Bell Labs. This semiconductor device enabled the miniaturization of electronic circuits and laid the foundation for modern electronic devices, including computers. Their work earned them the Nobel Prize in Physics in 1956, highlighting the transformative impact of the transistor on technology.
Today's computer would be nothing like it is now without the microprocessor. Most every electronic device has a microprocessor in it, from garage door openers, to remote controls, and cell phones. The microprocessor revolutionized electronics, giving them intelligence, and making our lives easier. Thus, it revolutionized the computer industry.
