Farnsworth’s Barely Visible Line

September 7, 1927

American engineer Philo T. Farnsworth transmits an electronic moving image – a barely visible “line picture” – to the delight of his technicians and investors. Nine months earlier, on January 7, Farnsworth applies for a patent for the dissector tube, the basis of today’s all-electronic television, and receives it three years later in August 1930.
