Inspired by a trip to Xerox's Palo Alto Research Center (PARC), engineers from Apple began working on a commercial application for the graphical interface ideas they had seen there. The resulting machine, Lisa, was expensive and never achieved any level of commercial success, but in 1984 another Apple computer, using the same WIMP (Windows, Icons, Menus, Pointer) interface concept, was launched. An advert during the 1984 Super Bowl, directed by Ridley Scott introduced the Macintosh computer to the world (in fact, the advert had been shown on a local TV channel in Idaho on 31 December 1983 and in movie theaters during January 1984 before its famous "premiere" on 22 January during the Super Bowl).
