In 1902, Morgan created the International Harvester Company, which monopolised America's agricultural machinery industry. That same year, he put together International Mercantile Marine (IMM), a conglomerate formed to monopolise transatlantic shipping that included White Star, the parent company of the Titanic.
The venture was less successful than Morgan's forays into railroads, electricity, and steel, though it wasn't his biggest failure. In the early 1900s, he lost $150,000, the equivalent of $5.5 million (£4.2m) today, funding Nikolai Tesla's disastrous Wardenclyffe Tower wireless transmission project. However, Morgan's most significant setback was his London Underground misadventure dubbed "the Morgan Tube".
