Time magazine named the personal computer its "Man of the Year. Postwar Innovations ENIAC and other early computers proved to many universities and corporations that the machines were worth the tremendous investment of money, space and manpower they demanded.

At the same time, new technologies were making it possible to build computers that were smaller and more streamlined. InBell Labs introduced the transistor, an electronic device that carried and amplified electrical current but was much smaller than the cumbersome vacuum tube.

But one of the most significant of the inventions that paved the way for the PC revolution was the microprocessor. Before microprocessors were invented, computers needed a separate integrated-circuit chip for each one of their functions.

This was one reason the machines were still so large. Microprocessors were the size of a thumbnail, and they could do things the integrated-circuit chips could not: The first microprocessor on the market was developed in by an engineer at Intel named Ted Hoff.

The Invention of the PC These innovations made it cheaper and easier to manufacture computers than ever before.

Compared to earlier microcomputers, the Altair was a huge success: However, it really did not do much.

Invention of the PC: The Computer Age

It had no keyboard and no screen, and its output was just a bank of flashing lights. Users input data by flipping toggle switches. The software made the computer easier to use, and it was a hit. This computer, called the Apple I, was more sophisticated than the Altair: It had more memory, a cheaper microprocessor and a monitor with a screen.

Also, users could store their data on an external cassette tape. Apple soon swapped those tapes for floppy disks. For example, a spreadsheet program called VisiCalc made the Apple a practical tool for all kinds of people and businesses —not just hobbyists. Soon companies like Xerox, Tandy, Commodore and IBM had entered the market, and computers became ubiquitous in offices and eventually homes.

Examples of the Census Bureau's innovations include the punch card and electronic tabulator technology developed by Herman Hollerith to speed the tallying of the census. The Census Bureau continued updating and using Hollerith's electronic tabulators until the census when they were replaced by UNIVAC I, the first modern computer.
