The Future of Vacuum Tubes & What Might Have Been

Send us a textIn the late 1800s, researchers were seeking a way to amplify an analog signal. The vacuum tube was invented in the early 1900s, but scientists were also investigating the properties of semiconductor materials. A very crude version of a transistor was developed even before the vacuum tube, but the technology of the day was better suited for tubes than transistors, and once the tube was widely available, research into the transistor was largely abandoned for the next 40 years.
