Hollerith founded the Tabulating Machine Company (1896) which was one of four companies that were amalgamated (via stock acquisition) to form a fifth company, Computing-Tabulating-Recording Company (CTR) (1911), later renamed International Business Machines Corporation (IBM) (1924). Other companies entering the punched card business included The Tabulator Limited (1902) (later renamed the British Tabulating Machine Company), Deutsche Hollerith-Maschinen Gesellschaft mbH (Dehomag) (1911), Powers Accounting Machine Company (1911) (later acquired by Remington Rand), Remington Rand (1927), and H. W. Egli Bull (1931). These companies, and others, manufactured and marketed a variety of punched cards and unit record machines for creating, sorting, and tabulating punched cards, even after the development of electronic computers in the 1950s.
