An art movement that emerged at the same time in the United Kingdom and the United States in the mid-twentieth century, as a reaction against Abstract Expressionism. The movement drew its inspiration from the aesthetics of comics and advertising, and functioned as a critique of consumerism and the capitalist society of its time. Its greatest exponents are Richard Hamilton (1922-2011) in England and Andy Warhol (1928-1987) in the United States.
