Baird's Televisor

Baird's Televisor, developed by John Logie Baird in the 1920s, was an early mechanical television system that transmitted live images. It used a spinning disk with tiny holes (a Nipkow disk) to scan images and convert them into electrical signals. These signals were sent over wires and then reconstructed into images on a screen using a similar disk. Although primitive compared to modern TVs, it demonstrated the concept of transmitting moving pictures electronically, laying the groundwork for future television technology. Baird's Televisor was a pioneering step in visual communications, showcasing the potential for broadcast television.
