early television technology

Early television technology emerged in the early 20th century, primarily based on mechanical and electronic systems to transmit images and sound. The first televisions used spinning disks to scan images, while later innovations introduced the cathode ray tube (CRT) for clearer visuals. Signals were broadcasted over radio frequencies, allowing viewers to watch programs in their homes. Pioneers like Philo Farnsworth and John Logie Baird contributed significantly to its development. By the late 1940s, television became more accessible, revolutionizing entertainment, information dissemination, and culture, eventually leading to the modern digital television we enjoy today.
