During the early -to-mid-1800s, what was the primary subject of american artists

Pop art started with the New York artists Andy Warhol, Roy Lichtenstein, James Rosenquist, and Claes Oldenburg, all of whom drew on popular imagery and were actually part of an international phenomenon. Following the popularity of the Abstract Expressionists, Pop's reintroduction of identifiable imagery (drawn from mass media and popular culture) was a major shift for the direction of modernism. The subject matter became far from traditional "high art" themes of morality, mythology, and classic history; rather, Pop artists celebrated commonplace objects and people of everyday life, in this way seeking to elevate popular culture to the level of fine art. Perhaps owing to the incorporation of commercial images, Pop art has become one of the most recognizable styles of modern art.
