as "wireless telegraphy") inventions of Guglielmo Marconi. As part of worldwide expansion, in 1899 American Marconi was organized as a subsidiary company, holding the rights to use the Marconi patents in the United States and Cuba. In 1912 it took over the assets of the bankrupt United Wireless Telegraph Company, and from that point forward it became the dominant radio communications company in the United States. When the United States entered World War I in April 1917, the government took control of most civilian radio stations in order to use them for the war effort. Although the government planned to restore civilian ownership of the radio stations once the war ended, many United States Navy officials hoped to retain a monopoly on radio communication even after the war. Contrary to instructions it had received, the Navy began purchasing large numbers of radio stations. When the war ended, Congress rejected the Navy's efforts to have peacetime control of the radio industry and instructed that the Navy return the stations it had taken control of to the original owners. Due to national security considerations, the Navy was particularly concerned about returning high-powered international stations to American Marconi, since the majority of its stock was in foreign hands, and the British already largely controlled the international undersea cables. This concern was increased by the announcement in late 1918 of the formation of the Pan-American Wireless Telegraph and Telephone Company, a joint venture between American Marconi and the Federal Telegraph Company, with plans to set up service between the United States and South America. The Navy had installed a high-powered Alexanderson alternator, built by General Electric (GE), at the American Marconi transmitter site in New Brunswick, New Jersey. It proved to be superior for transatlantic transmissions to the Spark-gap transmitters that had been traditionally used by the Marconi companies. Marconi officials were so impressed by the capabilities of the Alexanderson alternators that they began making preparations to adopt them as their standard transmitters for international communication. A tentative plan made with General Electric proposed that over a two-year period the Marconi companies would purchase most of GE's alternator production. However, the U.S. Navy objected to the plan, fearing British domination in international radio communications and the national security concerns this raised. The Navy, claiming support from President Wilson, looked for an alternative that would result in an "all-American" company taking over the American Marconi
