An evening pause: This 9-minute documentary, made in 1952 by Bell Labs, provides a short and clear history of the transistor as well as its predecessor, the vacuum tube. It also tries to imagine the future that such a new invention might bring. As the youtube page notes,
While The Transistor’s vision of the future seems somewhat quaint in retrospect, it captures a moment in time before the transistor became ubiquitous; a time when Bell Labs wanted the world to know that something important had occurred, something that was about to bring tremendous change to everyone’s daily lives.
