IBM has been well known through most of its recent history as one of the world's largest computer companies and systems integrators.

The company has scientists, engineers, consultants, and sales professionals in over 175 countries. IBM employees have earned five Nobel Prizes, four Turing Awards, five National Medals of Technology, and five National Medals of Science.

The roots of IBM date back to the 1880s. Since the 1960s or earlier, IBM has described its formation as a merger of three companies: The Tabulating Machine Company (with origins in Washington, D.C. founded in 1896), the International Time Recording Company (founded 1900 in Endicott), and the Computing Scale Company (founded 1901 in Dayton, Ohio, USA). However the 1911 stock prospectus states that four companies were consolidated; the three described by IBM and the Bundy Manufacturing Company (founded in 1889). Further, there was no merger, no consolidation. The new company, named the Computing-Tabulating-Recording Company(CTR), was incorporated on June 16, 1911 in the state of New York, U.S.A. CTR was a holding company; the now five companies were an amalgamation. The individual companies continued to operate using their established names until the holding company was eliminated in 1933. The amalgamation was engineered by noted financier Charles Flint. Flint remained a member of the board of CTR until his retirement in 1930.
