Farnsworth's invention of the electronic television

Philo Farnsworth revolutionized television by developing the first fully electronic system for transmitting images. He designed a device called the image dissector, which converts visual information into electronic signals by scanning an image line by line. These signals are then transmitted over a wire or airwaves and received by a similar device, which reconstructs the image on a screen. Farnsworth's innovation enabled live, high-quality television broadcasts without the mechanical parts used in earlier systems, paving the way for the modern electronic television we use today. His work laid the foundation for the digital broadcasting era.
