How did edison and westinghouse spread the use of electricity

At night the fair was lit by electricity. Who would light the fair would soon light the World. Edison and Westinghouse both put in bids to light the fair. General Electric Company (Edison’s and Morgan’s company) first bid to light the fair for $1.8 million. That bid did not go over well. The two did a second bid worth $554,000. Unbeknownst to General Electric, George Westinghouse, armed with Tesla’s new induction motor, proposed to light the fair for $399,000. Westinghouse won the contract. The effect of winning the bid would change history. Tesla's AC polyphase system would be on display for not only the US to see but the whole world. Originally, Tesla planned on using GE bulbs but Edison, still miffed, would not sell to Tesla and Westinghouse. Instead, Westinghouse came up with a more efficient double-stopper light bulb.
