One of the first computers "ENIAC" is publicly announced
ENIAC is one of the first electronic computers to exist. It was a secret project that was made to make calculations such as missile trajectories easier and less time consuming. ENIAC was massive, weighing 30 tons, contained 17,500 vacuum tubes, and was linked by 500,000 soldered connections. The exact date of it's reveal to the public is unknown. http://www.ushistory.org/oddities/eniac.htm -
The Transistor is invented
The transistor is an electronic device that carries elecrical currents. It is much smaller and much less bulky than the vacuum tube, opening many more opportunities for computers. The exact date of invention is unknown. http://www.history.com/topics/inventions/invention-of-the-pc -
The Invention of the Integrated Ciruit
Scientists at Texas Instruments and Fairchild Semiconductor invented the integrated circuit. This allowed for much more compact circuitry, as it combined all of a computer's electrical parts into one small chip. Exact date unknown. http://www.history.com/topics/inventions/invention-of-the-pc -
The Invention of the Microprocessor

The Altair Build-it-Yourself Computer Kit
The Altair was a big success that sold thousands of copies although it did very little, as it had no keyboard, mouse, or screen, and users input data with switches. Exact date unknown. http://www.history.com/topics/inventions/invention-of-the-pc -
BASIC Programming Language for Altair created
Paul G. Allen and Bill Gates created the BASIC programming language for the Altair. This made it easier to use. They would go on to make microsoft. Exact date unknown. http://www.history.com/topics/inventions/invention-of-the-pc -
The "Apple 1" created
Two people in Silicon valley known as Steve Jobs and Stephen Wozniak created the Apple 1, a computer more sophisticated than the Altair.
