Taʼrif
English: Regency TR-1 transistor radio, the first commercial transistor radio, which debuted October 18, 1954. Designed by Texas Instruments and IDEA, the TR-1 had a superheterodyne circuit with only 4 transistors: a combined local oscillator/mixer, two IF amplifiers, and one audio amplifier. Within one year of release, TR-1 sales approached 100,000. The transistor radio was the most popular communications device in history, with billions manufactured during the 1960s and 1970s.
