Story Highlights

  • historical event:
  • The first transistor radio was called Regency TR-1 (TR is short for Transistor Radio), and it was made jointly by Texas Instruments and I.D.E.A. (Industrial Development Engineering Associates). The radio had only four transistors, which means the sound was of low quality.

On this day it was announced that the first radio based on transistor circles has become available. Previous transistors were based on cathode ray tubes and were thus large and unwieldy. The first transistor radio was called Regency TR-1 (TR is short for Transistor Radio), and it was made jointly by Texas Instruments and I.D.E.A. (Industrial Development Engineering Associates).

The radio had only four transistors, which means the sound was of low quality, but the radio itself was small and easily portable, which was its main advantage. Its price was 49.95 U.S. dollars, and as many as 100,000 were sold within a year.
