During the years of depression, war, and postwar expansion, mahjong evolved in the United States and abroad, creating discrete national, regional, and community forms. In the 1940s, the wives of Air Force officers created their own version, which continued to spread across postwar bases. The most influential community adaptation by far was driven by the National Mah Jongg League. Over the ensuing decades, eventually hundreds of thousands of players, mostly but not exclusively Jewish American women, played their “National” version of the international Chinese game. The changes to the game that the League initiated were enabled by their proximity to the small factories making the tiles. The locus of mahjong manufacturing for the American market moved from China to plastic fabricating shops in New York City. As factories developed in concert with distinctive regional and community-based forms of the game, American mahjong grew into a domestic industry.
