Pop art emerged in the mid-1950s in England and spread to New York in the early 1960s. It reflected popular culture and everyday objects rather than traditional fine art themes. Pop artists like Andy Warhol, Roy Lichtenstein, and David Hockney appropriated images from advertisements, comics, and consumer goods to blur lines between high and low art. Their use of techniques like silkscreening and repetition challenged notions of what art could be. Pop art's legacy lives on in contemporary artists who reference mass media and question societal values.
