Pop art is an art form first introduced in Great Britain, towards the end of the 1950s. It was brought about by artists who wanted to take the stuffiness out of 'abstract expressionism', and bridge the gap between art and the public. This they did by including everyday objects like flags and soup cans in their paintings.
The birth of pop art was to ridicule the monotony that a section of artists associated with abstract expressionism. At the point of time, both the American as well as the British society was recuperating after the World War II, and these artists took potshots at the materialism all around and included objects like Coke cans and comic strips in the paintings. Artist Jasper Johns used the American flag to a large extent, Roy Lichtenstein gave prominence to comic strips, and Andy Warhol made soup cans famous, while stuffed animals were Robert Rauschenberg's choice of object. These artists included everyday objects in their paintings to make them more appealing to the common man. Art before that was largely confined to the high echelons of society, and the abstract art form was not understood by the layman. Pop artists changed all that by replacing the monotony of art with humor and relevance to daily life.
Pop art did receive its fair share of criticism, as art critics though it was a cheap effort to popularize everyday objects as symbols of art. American society, on the other hand, welcomed pop art with open arms, making it what it is today.
