Pop Art reacted against high art and embraced popular culture and mass production. It developed in America and Britain in the 1950s-60s and used techniques like silkscreening to depict popular icons and commercial products. This changed the public view of what art could be by blurring the lines between high and low art. Other movements discussed include Op Art, Minimalism, performance art, and Fluxus, which incorporated new mediums and concepts that further expanded the meaning and experience of art. Key artists mentioned include Andy Warhol, Jasper Johns, Robert Rauschenberg, Roy Lichtenstein, Claes Oldenburg, and Joseph Beuys.
