Pop Art made commentary on contemporary society and culture, particularly consumerism, by using popular images and icons and incorporating and re-defining them in the art world. Often subjects were derived from advertising and product packaging, celebrities, and comic strips. The images are presented with a combination of humor, criticism and irony. In doing this, the movement put art into terms of everyday, contemporary life. It also helped to decrease the gap between "high art" and "low art" and eliminated the distinction between fine art and commercial art methods".
