Pop art emerged in the 1950s-1970s and focused attention on mass production and popular culture by reproducing images and styles from advertisements, comics, and everyday consumer items. Leading pop artists included Eduardo Paolozzi, John McHale, Andy Warhol, Robert Rauschenberg, and Jasper Johns in both Britain and the United States, with the Independent Group in Britain and American artists like Warhol and Rauschenberg producing iconic pop art works that referenced commercial culture.
