Machines That Built the World S01E07 - Tesla vs Marconi

In 1893, sending information across America was a time-consuming process, prompting two rival inventors to try to improve things by introducing wireless communication. Nikola Tesla was one of the most famous and successful thinkers of his day, single-handedly changing the way electricity was supplied and generated. Guglielmo Marconi was a young, uneducated Italian inventor who ignored scientific consensus and went with his gut. Both wanted to rid the world of wires and send messages through the air. With millions of dollars on the line, the two men battled to dominate the new market and bring radio to the masses.
