Pop Art, Minimalism, and Conceptual Art revolutionized the art world in the mid-20th century. These movements challenged traditional notions of art, embracing popular culture, simplicity, and ideas over objects. They blurred the lines between high and low art, paving the way for new forms of artistic expression. Key artists like Andy Warhol, Frank Stella, and Sol LeWitt pushed boundaries with their innovative approaches. Their work continues to influence contemporary art, design, and culture, shaping our understanding of what art can be and how it interacts with everyday life.
