Pop art is an art movement that emerged in the mid-20th century, primarily in the United States and the United Kingdom. It is characterized by its focus on popular culture, using imagery from advertisements, comic books, and everyday objects. Artists like Andy Warhol and Roy Lichtenstein often employed bright colors and bold lines to create works that challenged traditional art forms. The movement aimed to blur the boundaries between high art and low culture, making art more accessible to the general public. By incorporating mass media and consumerism into their work, pop artists reflected the changing social landscape of the time, celebrating and critiquing the rise of consumer culture.
