The Marconi Wireless Telegraph Company of America, often referred to as American Marconi, was founded in 1899 as a subsidiary of the British Marconi Company. It possessed the exclusive rights to Guglielmo Marconi's radio (or "wireless telegraphy") patents in both the U.S. and Cuba. At the outset, American Marconi concentrated on managing high-powered land stations and transatlantic shipboard stations.
In 1912, it acquired the assets of the defunct United Wireless Telegraph Company, thereby establishing itself as the foremost radio communications provider in the United States.

During World War I, the U.S. government assumed control of the radio industry, and following the war, it hesitated to return American Marconi's stations to British ownership due to concerns regarding national security. Under the leadership of the U.S. Navy, the government exerted pressure on the Marconi companies to transfer ownership of American Marconi to a U.S. entity. In 1919, General Electric acquired the assets of American Marconi, which laid the groundwork for the establishment of its new subsidiary, the Radio Corporation of America (RCA).

The British parent company, initially established as the Wireless Telegraph and Signal Company, Limited, in London on July 20, 1897, was created to advance Marconi's radio inventions. It was renamed Marconi's Wireless Telegraph Company, Limited (or "British Marconi") in March 1900, with the aim of broadening its global presence by forming subsidiaries with regional rights to the Marconi patents. American Marconi, incorporated in New Jersey on November 8, 1899, was the first of these subsidiaries, holding the exclusive rights to utilize the Marconi patents in the United States, as well as in the Hawaiian Islands, Philippine Islands, Cuba, Puerto Rico, Alaska, and the Aleutian Islands.
