Neo-Dada was a movement with audio, visual and literary manifestations that had similarities in method or intent with earlier Dada artwork. In the United States the term was popularized by Barbara Rose in the 1960s and refers primarily, although not exclusively, to work created in that and the preceding decade. There was also an international dimension to the movement, particularly in Japan and in Europe, serving as the foundation of Fluxus, Pop Art and Nouveau réalisme.
Neo-Dada was exemplified by its use of modern materials, popular imagery, and absurdist contrast. It was a reaction to the personal emotionalism of Abstract Expressionism and, taking a lead from the practice of Marcel Duchamp and Kurt Schwitters, denied traditional concepts of aesthetics.
