A term coined by the English critic Lawrence Alloway to describe a movement in modern art which flourished, mainly in the United States and Britain, from the late 1950s to the early 1970s. Pop art drew its imagery from the world of consumerism and popular culture, claiming no distinction between good and bad taste. In a sense it gave validity to a new iconography based on the culture of the everyday.
