Philo Farnsworth: Invents EV

One day in 1921, while cutting hay, 15-year-old Philo Farnsworth figured out how to send sound and pictures through the air by electricity—what we call television. But even though he knew how he wanted television to work, it took Philo years of scientific tests and experiments to make it actually work. During these years, Philo constantly struggled to find enough money to conduct these tests. Then, just when he was near success, new problems arose.

This is the fascinating story of Philo Farnsworth—the father of television. His dream changed the world.
