Googie, Also Known as Populuxe or Doo-wop -

From Wiki:

Googie, also known as populuxe or doo-wop, is a subdivision of futurist architecture, influenced by car culture and the Space Age and Atomic Age, originating from Southern California in the late 1940s and continuing approximately into the mid-1960s. The types of buildings that were most frequently designed in a Googie style were motels, coffee houses and bowling alleys.

Features of Googie include upswept roofs, curvaceous, geometric shapes, and bold use of glass, steel and neon. Googie was also characterized by space-age designs that depict motion, such as boomerangs, flying saucers, atoms and parabolas, and free-form designs such as "soft" parallelograms and the ubiquitous artist's-palette motif. These stylistic conventions reflected American society's emphasis on futuristic designs and fascination with Space Age themes. The style is related to and sometimes synonymous with the Raygun Gothic style as coined by writer William Gibson. As with the art deco style of the 1930s, Googie became undervalued as time passed, and many buildings built in this style have been destroyed.
