One of the most influential technologies of the past hundred years has been motion pictures. Not only are movies big business, but they are also a large part of popular culture. They have an enormous impact on how people perceive the world and how people behave, as they provide information, elicit empathy, and shape everyday behavior. This entertainment medium and art form began more than a hundred years ago as a relatively simple technology of motion-picture camera and projector. Since then, continual technological innovation has improved the medium, all the while expanding its expressive possibilities.
