NLS (computer system)

NLS, or the "oN-Line System", was a revolutionary computer collaboration system from the 1960s. Designed by Douglas Engelbart and implemented by researchers at the Augmentation Research Center (ARC) at the Stanford Research Institute (SRI), the NLS system was the first to employ the practical use of hypertext links, the mouse, raster-scan video monitors, information organized by relevance, screen windowing, presentation programs, and other modern computing concepts. It was funded by the Defense Advanced Research Projects Agency, NASA, and the U.S. Air Force.
