Pop art was a visual artistic movement that emerged in the early 1950s in Britain and in parallel in the late 1950's in the United States. Pop art is one of the major art movements of the Twentieth Century. Characterized by themes and techniques drawn from popular mass culture, such as advertising and comic books, pop art is widely interpreted as either a reaction to the then-dominant ideas of abstract expressionism or an expansion upon them. Pop art, like pop music, aimed to employ images of popular as opposed to elitist culture in art, emphasizing the banal or kitschy elements of any given culture. Pop art at times targeted a broad audience, and often claimed to do so. However, much of pop art is considered very academic, as the unconventional organizational practices used often make it difficult for some to comprehend. Pop art and Minimalism are considered to be the last Modern art movements and thus the precursors to Contemporary art or Postmodern art.
