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!
ReplyDeleteWow! Chet Huntley!
"And with that, good night Chet, good night David!"
His was the only name in the credits that I recognized!

ReplyDeleteis 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.
