This is a really OLD video, but there is a lot of great material here:
— Tubes. (Valves or Thermatrons)
— Coax.
— Frequency Division Multiplexing.
— Negative Feedback and the fight against distortion.
— Transistors and early experiments with semiconductors.
— Fiber optics and Masers.
— Satellite communications.
— Early hopes for video communications.
The video is, by today’s standards, extremely misogynist. And the sound experiment with the poor woman wearing a male head was just weird. But still, an interesting film.
Thanks to Mark KM4GML for reminding us of this wonderful Bell Labs (AT&T) video archive.
Very good. True, quite misogynist! Wow! Chet Huntley! “And with that, good night Chet, good night David!”
His was the only name in the credits that I recognized!
The AT&T Tech Channel At https://www.youtube.com/@ATTTechChannel is replete with such goodies. And although the company is different now, it hasn’t forgotten its past. Inside AT&T Labs, Bedminster, NJ you are greeted by a bust of Claude Shannon in the hallway.
All destroyed by Judge Green. People don’t even recall the name Bell Telephone Laboratories.
