International Business Machines, abbreviated IBM and nicknamed "Big Blue", is a multinational computer technology and IT consulting corporation headquartered in Armonk, New York, United States. The company is one of the few information technology companies with a continuous history dating back to the 19th century. IBM manufactures and sells computer hardware and software (with a focus on the latter), and offers infrastructure services, hosting services, and consulting services in areas ranging from mainframe computers to nanotechnology.[1] Ginni Rometty is the president and CEO of IBM. IBM has been well known through most of its recent history as one of the world's largest computer companies and systems integrators.[2] With over 388,000 employees worldwide, IBM is one of the largest and most profitable information technology employers in the world. IBM holds more patents than any other U.S. based technology company and has eleven research laboratories worldwide.[3] The company has scientists, engineers, consultants, and sales professionals in over 170 countries.[4] IBM employees have earned five Nobel Prizes, four Turing Awards, five National Medals of Technology, and five National Medals of Science.[5] Contents
