Beginning in the mid-1920s, the Art Deco movement was the predominant style of decorative arts for nearly two decades. Considered highly modern at the time, its popularity encompassed painting, film, architecture and interior design. Art Deco proved to be a mix of many previous styles, including Art Nouveau, Neoclassical, Modernism, Cubism and Futurism. The movement began in France and is generally based on mathematical principles. After a decline following World War II, Art Deco's popularity was revived again in the 1980s, particularly in the field of graphic design; it was later a prominent influence on the Pop Art movement. Two of New York City's most famous landmarks--the Empire State Building and the Chrysler Building--are among the world's best surviving examples of Art Deco architecture.
