9. Open Question: Explain the importance of the iconoscope’s development in the history of television.
The iconoscope was the first practical vídeo camera tube used in early television cameras. It was fundamental because it converted visual images into electrical signals, making electronic television possible.
The early mechanical system used rotating disks and was limited in resolution and speed. The electronic system, however, used electronic scanning and transmission, producing clearer and more reliable images.
