In 1957 pop artist Richard Hamilton listed the ‘characteristics of pop art’ in a letter to his friends the architects Peter and Alison Smithson:
Pop Art is: Popular (designed for a mass audience), Transient (short-term solution), Expendable (easily forgotten), Low cost, Mass produced, Young (aimed at youth), Witty, Sexy, Gimmicky, Glamorous and Big business.
In the United States, pop style was a return to representational art (art that depicted the visual world in a recognisable way) and the use of hard edges and distinct forms after the painterly looseness of abstract expressionism. By using impersonal, mundane imagery, pop artists also wanted to move away from the emphasis on personal feelings and personal symbolism that characterised abstract expressionism.
In Britain, the movement was more academic in its approach. While employing irony and parody, it focused more on what American popular imagery represented, and its power in manipulating people’s lifestyles. The 1950s art group The Independent Group (IG), is regarded as the precursor to the British Pop art movement.
