Somewhat more mechanization.
Dr Allen B. DuMont mostly invented the service oscilloscope, but in 1953 he was bragging on his TV work.
This is wrong: a male tube maker in the Czech Republic.

I've only watched the RCA one so far and man do I see a lot of repetitive motion injuries going on for all those gals. Honest work but they probably paid a price. Very similar to the shoe factories I have visited, only by the 80's they had figured out rotating work station assignments to break the routine up, where needed counterbalance arm slings from the ceilings so simply holding the weight of your own arms up for 8 hours was less of an issue and at least a passing nod to station ergonomics.
