History’s greatest tech battles: Edison vs Tesla

In the 1880s, two brilliant minds sparked one of history’s greatest tech battles: Edison versus Tesla.

Thomas Edison—relentless inventor, brilliant marketer—pushed for Direct Current: DC. He believed a steady, one-directional flow of electricity was the future.

Then came Nikola Tesla. A visionary, a dreamer—he believed in Alternating Current: AC. It could travel farther, faster, and more efficiently.

The rivalry got shocking—literally. Edison, determined to discredit AC, staged public demonstrations, electrocuting animals to stir fear. Meanwhile, Tesla’s AC lit up the 1893 World’s Fair and even powered Niagara Falls.

In the end, Tesla’s AC won the war of currents. But the story didn’t end there.

Edison built General Electric and shaped America’s electrical future. Tesla? He imagined wireless power and endless energy—but died broke and mostly forgotten.

Today, cities around the world run on Tesla’s AC. And his legacy? It's stronger than ever.

Two minds. One electric legacy. Edison sparked the system. Tesla energized the dream. Who changed the world?

Maybe... both.
