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!

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.
