Why did art deco end?

Art Deco began to decline after World War II due to changing tastes and the rise of modernism, which favored minimalism and functional design over the ornate styles of Art Deco. The economic shifts and the need for practicality led to a preference for simpler, more utilitarian forms. Additionally, the post-war period saw a cultural movement towards new materials and technologies, further distancing design from the lavish aesthetics of Art Deco.
