First Transistor Radio Goes on Sale
November 1, 1954 The Industrial Development Engineering Associates company begins selling the Regency TR-1, the world’s first commercial transistor radio. Texas Instruments designed and developed the transistor technology who then partnered with IDEA to design and manufacturer the completed radio. The TR-1 sold over 100,000 units, ushering in the commercial transistor industry. First Transistor Radio Goes…

The First Transistor Calculator
October 7, 1954 IBM researchers modify an existing model 604 vacuum tube calculator to use transistors. This experiment didn’t shrink the desk-sized machine nor make it any faster, but it did use only 5% of the power the vacuum tube-based design did. Encouraged by this successful experiment, IBM introduced the first commercial transistor calculator 4…

Transistor Patented
October 3, 1950 AT&T Bell Laboratories researchers John Bardeen, Walter Brattain, and William Shockley receive a US Patent for their invention of the transistor, which they had successfully demonstrated two years earlier. The transistor completely revolutionized the development of electronic and computerized technology. Transistor Patented is original content of This Day in Tech History. This Day…
