The United Wireless Telegraph Company was the largest radio communications company in the United States, beginning with its late-1906 formation, until its bankruptcy and takeover by Marconi interests in mid-1912. Although at the time of its demise the company was operating around 70 land and 400 shipboard radiotelegraph installations — by far the most in the U.S. — the firm`s management had showed substantially more interest in fraudulent stock promotion schemes than in ongoing operations or technical development. United Wireless` shutdown was hailed as eliminating one of the major financial frauds of the period, however, its disappearance also left the U.S. radio industry largely under foreign influence, dominated by the British-controlled American Marconi.
