Pop Art emerged in the 1950s as a reaction to Abstract Expressionism, using imagery from popular culture and mass media. Major pop artists like Andy Warhol, Roy Lichtenstein, Jasper Johns, and Robert Rauschenberg incorporated symbols, objects, and graphics from advertisements, product packaging, and other commercial art into their brightly colored, photo-realistic paintings and sculptures. Pop Art blurred the lines between high and low art to comment on the growing role of consumerism and mass production in postwar Western culture.
