The Science Magazine of the Air takes you back many years, to 1906, when inventor, Lee De Forest, filed his first patent for an electronic amplifying vacuum tube he'd invented, describing it as a detector of sound, which he named the Audion. This inspired piece of equipment finally made live radio broadcasting possible, and it would go on to become the key component of all radio, long distance telephone calls, radar, television, and even early computer systems!
