In the post-World War I era, Terrazzo became a flooring of choice in the US, suddenly overtaking and replacing the use of marble mosaics, for several reasons. Architects were the first ones to recognize the vast design potential of terrazzo. Terrazzo happened to be the ideal medium for its ability to offer smooth,
curvilinear art deco and modern styles. Furthermore, the invention of the electric grinder in 1924 brought about a finer finish, greater speed and accuracy at lowered costs, all contributing to the spread of terrazzo all over the US.
Many of the country's most noteworthy buildings of the day, stunning examples of classic design, craftsmanship and durability were built with terrazzo, including the State Building, Radio City Music Hall and the Frank Lloyd Wright-designed Solomon R. Guggenheim Museum.
Also in 1924, Terrazzo and mosaic contractors from all over the US created the National Terrazzo and Mosaic Contractors Association, today known as the National Terrazzo and Mosaic Association, Inc.
