In 1888, American inventor and businessman Herman Hollerith devised a punched card system, including the punching equipment, for tabulating the results of the United States Census. Hollerith's machines used electrically charged nails that, when passed through a hole punched in a card, created a circuit.

The circuits registered on another part of the machine, where they were read and recorded. Hollerith's machines tabulated the results of the 1890 Census, making it the fastest and most economical Census up to that date. In a single day 56 of these machines could tabulate Census information about more than 6 million people. Governments, institutions, and industries found used for Hollerith's machine.

In 1896, Hollerith founded the Tabulating Machine Company. He continued to improve his machines. In 1911 he sold his share of the company. Its name was changed to the Computing-Tabulating-Recording Company (C-T-R). In 1924, the name was changed to International Business Machines Corporation (IBM).
