The origins of the International Business Machines Corporation can be traced to Herman Hollerith, who founded the Tabulating Machine Company in 1896 to classify census data using card readers that sensed holes punched in the cards. After merging with two other companies, the Computing Scale Company and the International Time Recording Company, the Computing-Tabulating-Recording Company, or C-T-R, was formed in 1911. In 1924, the name of the company was changed to International Business Machines Corporation, or IBM, as business expanded to overseas markets.
