Final answer:
Pop Art, particularly exemplified by Andy Warhol's 'Campbell Soup Can' painting, bridged the gap between high and commercial art by incorporating everyday mass-media items into artwork. It emerged in the post-World War II era, reflecting the fascination with American consumerism, and transformed the perception of art in the advertisement industry.
Step-by-step explanation:
Pop Art fundamentally shifted the boundaries between high art and commercial art through the use of mass media and advertising methods in fine artwork. The iconic artwork Campbell Soup Can by Andy Warhol popularized the notion of using original paintings and artwork in advertisements.
Warhol's work exemplified this new approach by taking an everyday object—an ordinary soup can—and transforming it into high art, thereby making a vibrant connection with the public who were familiar with such consumer goods.
In the environment of post-World War II, the fascination with American consumerism was not only a prominent theme but part of the historical context when Pop Art emerged. Artists such as David Hockney in the UK and Jasper Johns and Roy Lichtenstein in the US explored the interfaces between everyday consumer items, cultural icons, and art.
The approach was not just about the subject matter but the methods used, often replicating the serialized and bright style of mass production. In doing so, artists like Warhol challenged the existing boundaries of technique and subject matter, leading to a profound crossover between fine art and commercial art.
