A great world’s fair was held in Chicago, in 1893, to celebrate the 400th anniversary of Christopher Columbus’ arrival in America. It was known as the World’s Columbian Exposition, or the Chicago World’s fair. The War of the Currents was at its peak, then. General Electric, a company linked to Edison, submitted a bid to electrify the Fair using Edison’s direct current. But they lost the bid to George Westinghouse, who offered to provide Tesla’s alternating current at a much lower cost.
The AC power generation system of Tesla was less expensive, and required far less infrastructure than Edison’s DC system. From then on, AC became more preferred in the U.S., as well as throughout the world. That does not mean that DC totally vanished from the scene. Both the systems remained as complementary technologies.
