Toumey found that the published versions of Feynman's talk had a negligible influence in the twenty years after it was first published, as measured by citations in the scientific literature, and not much more influence in the decade after the Scanning Tunneling Microscope was invented in 1981. Interest in "Plenty of Room" in the scientific literature greatly increased in the early 1990s. This is probably because the term "nanotechnology" gained serious attention just before that time, following its use by Drexler in his 1986 book, Engines of Creation: The Coming Era of Nanotechnology, which cited Feynman, and in a cover article headlined "Nanotechnology", published later that year in a mass-circulation science-oriented magazine, OMNI.[24][25] The journal Nanotechnology was launched in 1989; the famous Eigler-Schweizer experiment, precisely manipulating 35 xenon atoms, was published in Nature in April 1990; and Science had a special issue on nanotechnology in November 1991.
