No, art deco has been around for a century after replacing art nouveau as a major decorative style after WWI...
It represented a machine age aesthetic, replacing flowing, floral motifs with streamlined, geometric designs that expressed the speed, power and scale of modern technology.
Design influences were many, from the modern art movements of Cubism, Futurism and Constructivism to ancient geometric design elements from the exotic cultures of Egypt, Assyria and Persia. In poster art, precursors were the German Plakatstil, the Viennese Secession and the Parisian fashion design revolution that began in 1908.
The style received its name from the Decorative Arts Exposition of Paris in 1925, which marked the full flowering of Art Deco design. Simplification and abstraction were always it's hallmarks, although the graceful elegance and exoticism of its early days yielded to a more muscular and forceful style in the late 1920s and 1930s.
That final phase is often called the "Cassandre Style" after its most famous artist, who enjoyed a one-man show at the Museum of Modern Art in 1936. Cassandre's sleek designs of towering ships and speeding trains are still considered the style's quintessential images.
