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 initialism. 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".
