International Business Machines Corporation (commonly referred to as IBM) is an American multinational technology and consulting corporation, with corporate headquarters in Armonk, New York. IBM manufactures and markets computer hardware, middleware and software, and offers infrastructure, hosting and consulting services in areas ranging from mainframe computers to nanotechnology.

The company originated in 1911 as the Computing-Tabulating-Recording Company (CTR) through the consolidation of The Tabulating Machine Company, the International Time Recording Company, the Computing Scale Company and the Bundy Manufacturing Company. CTR was renamed "International Business Machines" in 1924, a name which Thomas J. Watson first used for a CTR Canadian subsidiary. The initialism IBM followed. Securities analysts nicknamed the company Big Blue for its size and common use of the color in products, packaging and its logo.

In 2012, Fortune ranked IBM the second largest U.S. firm in terms of number of employees (435,000 worldwide), the fourth largest in terms of market capitalization, the ninth most profitable, and the nineteenth largest firm in terms of revenue. Globally, the company was ranked the 31st largest in terms of revenue by Forbes for 2011. Other rankings for 2011/2012 include №1 company for leaders (Fortune), №1 green company in the United States (Newsweek), №2 best global brand (Interbrand), №2 most respected company (Barron's), №5 most admired company (Fortune), and №18 most innovative company (Fast Company).

IBM (atoms)

IBM in atoms was a demonstration by IBM scientists in 1989 of a technology capable of manipulating individual atoms. A scanning tunneling microscope was used to arrange 35 individual xenon atoms on a substrate of chilled crystal of nickel to spell out the three letter company acronym. It was the first time atoms had been precisely positioned on a flat surface.

On Apr 30, 2013 IBM published an article on its website and a video on YouTube called "A Boy And His Atom: The World's Smallest Movie".

Research

Donald Eigler and Erhard Schweizer of the IBM Almaden Research Center in San Jose, California, used a scanning tunneling microscope to position 35 individual xenon atoms on a substrate of chilled crystal of nickel to form the acronym "IBM". They also created chains of xenon atoms similar in form to molecules.
