The roots of IBM date back to the 1880s. IBM has described its formation as a merger of three companies: The Tabulating Machine Company, the International Time Recording Company and the Computing Scale Company. Currently, IBM is the largest IT company in the world. It has representative offices in 170 countries.

Utworzona w 1894 przez Hermana Hollerithe firma TMC z powodu trudności finansowych połączyła się z Computing Scale Corporation i International Time Recording Company, aby utworzyć Computing Tabulating Recording Corporation (CTR). W 1924 r. CTR został ostatecznie przemianowany na International Business Machines Corporation (IBM).
