The origin of virtual reality is often attributed to a system developed by the [[Philco Corporation]] in 1958. In 1965, [[Ivan Sutherland]] (creator of the first computer pointer) spoke of tantalizing virtual worlds, and it was in 1966 that he conducted preliminary experiments in three dimensions. By the late 1970s, virtual reality was being developed as a tool for an aviation class in the U.S. Department of Defense for flight simulations.
