The International Business Machines Corporation (IBM) is an American multinational technology and consulting corporation, with headquarters in Armonk, New York, United States. IBM manufactures and markets computer hardware and software, and offers infrastructure, hosting and consulting services in areas ranging from mainframe computers to nanotechnology.
The company was founded in 1911 as the Computing Tabulating Recording Company (CTR) through a merger of three companies: the Tabulating Machine Company, the International Time Recording Company, and the Computing Scale Company. CTR adopted the name International Business Machines in 1924, using a name previously designated to CTR's subsidiary in Canada and later South America. Securities analysts nicknamed IBM Big Blue in recognition of IBM's common use of blue in products, packaging, and logo.
