This film works even today. Here we are, 80 years later, and so much of the world is still unaware of the impact the vacuum tube has made on modern society.

In the film, the guy is gesturing towards the tube in the transmitter cabinet. If we went to any modern day radio station, we would be making a video of virtually the same technology. Little signal in, GIANT SIGNAL OUT.

What a pity that they do this jump from Edison's lamp to the vaccum tube of de forst without mentioning the few yars of the Felming trube only from the UK.

Thi triode would not have been "that early" with out the fleming diode tube of 1904.
