Video games: they were something called Pong, a white ball bouncing from one side of a black screen to the other. The movie created both the technology for sophisticated video-game systems (ah, Space Invaders!) and the popular appetite to play them. Suddenly the must-have Christmas gift was a home-video player. You can trace a direct line from Star Wars to every video game since. For Grand Theft Auto you can say "Thank you, George Lucas!" or "Damn you, George Lucas!" And if kids ever got out of the house, they went to state-of-his-art theme parks, with Space Mountain (a Star Wars race in the dark), Lucas' own Star Tours and Indiana Jones rides. Many Disney World and Universal park attractions are film franchises at warp speed.
