Art Deco derived its name from the World's fair held in Paris in 1925, formally titled the Exposition Internationale des Arts Décoratifs et Industriels Modernes, which showcased French luxury goods and reassured the world that Paris remained the international center of style after World War I. Art Deco did not originate with the Exposition; it was a major style in Europe from the early 1920s, though it did not catch on in the U.S. until about 1928, when it quickly modulated into the Streamline Moderne during the 1930s, the decade with which Americanized Art Deco is most strongly associated today.

Paris remained the center of the high end of Art Deco design, epitomized in furniture by Jacques-Emile Ruhlmann, the best-known of Art Deco furniture designers and perhaps the last of the traditional Parisian ébénistes, and Jean-Jacques Rateau, the firm of Süe et Mare, the screens of Eileen Gray, wrought iron of Edgar Brandt, metalwork and lacquer of Swiss-Jewish Jean Dunand, the glass of René Lalique and Maurice Marinot, clocks and jewelry by Cartier.

The term Art Deco was coined during the Exposition of 1925 but did not receive wider usage until it was re-evaluated in the 1960s. Its practitioners were not working as a coherent community. It is considered to be eclectic, being influenced by a variety of sources, to name a few:

1) Early work from the Wiener Werkstätte; functional industrial design
2) "Primitive" arts of Africa, Egypt, or Aztec Mexico
3) Ancient Greek sculpture and pottery design of the less naturalistic "archaic period"
4) Léon Bakst's sets and costumes for Diaghilev's Ballets Russes
5) Fractionated, crystalline, facetted form of decorative Cubism and Futurism
6) Fauve color palette
7) Severe forms of Neoclassicism: Boullée, Schinkel
8) Everything associated with Jazz, Jazz Age or "jazzy"
9) Animal motifs and forms; tropical foliage; ziggurats; crystals; "sunbursts"; stylized fountain motifs
10) Lithe athletic "modern" female forms; flappers' bobbed haircuts
11) Machine age technology such as the radio and skyscraper.

Corresponding to these influences, the Art Deco is characterised by use of materials such as aluminium, stainless steel, lacquer, inlaid wood, sharkskin, and zebraskin. The bold use of zigzag and stepped forms, and sweeping curves (unlike the sinuous curves of the Art nouveau), chevron patterns, and the sunburst motif. Some of these motifs were ubiquitous — for example the sunburst motif was used in such varied contexts as a lady's shoe, a radiator grille, the auditorium of the Radio City Music Hall and the spire of the Chrysler Building. Art Deco was an opulent style and this opulence is attributed as a reaction to the forced austerity during the years of World War I. Art Deco was a popular style for interiors of cinema theatres and ocean liners such as the Ile de France and Normandie.

A parallel movement following close behind, the Streamline or Streamline Moderne, was influenced by manufacturing and streamlining techniques arising from science and the mass production shape of bullet, liners, etc., where aerodynamics are involved. Once the Chrysler Air-Flo design of 1933 was successful, "streamlined" forms began to be used even for objects such as pencil sharpeners and refrigerators. In architecture, this style was characterised by rounded corners, used predominantly for buildings at road junctions.

Some historians see Art Deco as a type of or early form of Modernism.

Art Deco slowly lost patronage in the West after reaching mass production, where it began to be derided as gaudy and presenting a false image of luxury. Eventually the style was cut short by the austerities of World War II. In colonial countries such as India , it became a gateway for Modernism and continued to be used well into the 1960s. A resurgence of interest in Art Deco came with graphic design in the 1980s, where its association with film noir and 1930s glamour led to its use in ads for jewelry and fashion. This is still the image of Art Deco held in the minds of most Americans.
