computer revolution

The tremendous impact computers have on society. There have been four computer revolutions. The first was when computers began to proliferate in the 1960s, which transformed business around the world. The second started in the late 1970s when consumers became computer customers for the first time. Without personal computers, the Internet, the third revolution, would not have flourished. The fourth revolution began with smartphones and tablets. Each revolution changed society in myriad ways. See computer ethics.

The Revolution Behind Everything
The heart of all these revolutions is the integrated circuit, otherwise known as the "chip," which is the most extraordinary invention of the modern era. See active area and chip.
