Stock printed by American Bank Note Co. “1912-Year of Titanic sinking.” Very Rare type! The Marconi Wireless Telegraph Company of America, commonly known as American Marconi, was established in 1899 as a subsidiary of the British Marconi Company. It held the exclusive rights to Guglielmo Marconi's radio (or "wireless telegraphy") patents in the U.S. and Cuba. Initially, American Marconi focused on operating high-powered land and transatlantic shipboard stations. In 1912, it acquired the assets of the bankrupt United Wireless Telegraph Company, making it the leading radio communications provider in the United States.

During World War I, the U.S. government took control of the radio industry, and after the war, it was reluctant to return American Marconi's stations to British ownership due to national security concerns. Led by the U.S. Navy, the government pressured the Marconi companies to transfer ownership of American Marconi to a U.S. entity. In 1919, General Electric purchased American Marconi's assets, which served as the foundation for the creation of its new subsidiary, the Radio Corporation of America (RCA).

The British parent organization, initially established as the Wireless Telegraph and Signal Company, Limited, in London on July 20, 1897, was created to advance Marconi's radio innovations. In March 1900, it was renamed Marconi's Wireless Telegraph Company, Limited (commonly referred to as "British Marconi") and aimed to broaden its international presence by forming subsidiaries that would possess regional rights to the Marconi patents. The first of these subsidiaries, American Marconi, was incorporated in New Jersey on November 8, 1899, and was granted exclusive rights to employ the Marconi patents within the United States, as well as in the Hawaiian Islands, the Philippine Islands, Cuba, Puerto Rico, Alaska, and the Aleutian Islands.
