Stollwerck turned their focus to exporting their products. Subsidiaries were formed in England, Belgium and Austria-Hungary. In 1894 Stollwerck founded "Volkmann, Stollwerck & Company" in the USA, in partnership with German businessman John Volkmann to produce vending machines in their factory in New York. By the early 1890s there were over 4,000 of its vending machines on New York train stations. It also became a leading manufacturer of cinematographs. In 1902 the company went public, but World War I brought Stollwerck's rapid expansion to a halt.
