Really nice article explaining how Lucas expanded filmmaking in revolutionary ways.

George Lucas always hated making movies the old-fashioned way. He has compared traditional, film-based movie production to wearing handcuffs and waging war. But instead of just complaining, Lucas decided that there had to be a better way--and he has dedicated much of his career to finding it. From the digital cameras that are replacing film cameras on movie sets, to the way movies are edited, to how special effects are created, to the sound we hear in theaters and at home, and even (soon) to the way movies are distributed to theaters, Lucas has led the way in adopting innovative technologies. Perhaps no one since Thomas Edison, who pioneered the essential technologies of celluloid, has had such a profound impact on the art of filmmaking.
