OTD in 1948, @BellLabs held 1st public demonstration of a solid-state device that amplified an electrical signal. They called it a "transistor." It supplanted vacuum tubes & led to development of integrated circuits & microchips, powering the computer age. https://t.co/ZB1BSE9dAc https://t.co/2UceUN9HCq — PolitiTweet.org
