What is lithography? What is the history of lithography? What is it used for today?

Lithography is a printing medium using a stone press on which areas are made receptive to ink, while other areas are not. The word "litho" means stone, which relates to the use of the stone press. Today, lithography is mainly used in modern-pop art and in printmaking.
