Pictures on the Wireless! A New Wonder for B.B.C Audience (1928) The British Broadcasting Corporation (B.B.C) was making waves in the world of entertainment with its latest innovation - the transmission of photographs and drawings over the wireless. This diagram illustrates the new method of synchronising negative images onto a rotating cylindrical screen, making it possible for the B.B.C audience to view visual content alongside radio broadcasts. The apparatus used in this groundbreaking transmission consisted of various machines and technical components. The transmitting machine was equipped with a copper foil cylinder and a high-frequency oscillator, which modulated the images onto the wireless waves. The receiving end featured a television-like screen, where the images were projected after being decoded by a dissecting tube and a selenium rectifier tube. This new system, known as the Fultograph, was an early attempt at television broadcasting. It was the brainchild of George Horace Davis, an American inventor who had been working on the concept since the late 1920s. The Fultograph used a photographic negative, which was scanned by an electron beam and then transmitted as electrical signals. The potential of this new technology was immense. It could revolutionise the way people consumed media, allowing them to experience both audio and visual content through their wireless sets. The B.B.C was at the forefront of this technological advancement, paving the way for a more interactive and engaging form of broadcasting. Despite the excitement surrounding this new wonder, it was still in its infancy. The Fultograph faced several challenges, including limited image quality and a relatively small audience reach. Nevertheless, it marked an important milestone in the history of broadcasting and laid the foundation for future developments in television technology.
