Regency TR-1 transistor radio. The Regency TR-1 was the first commercially manufactured transistor radio, introduced in 1954.Despite mediocre performance, about 150,000 units were sold, due to the novelty of its small size and portability.
An early 2000s transistor radio (Sony Walkman SRF-S84 transistor radio, released 2001, shown without earphones) Rock 'n roll music became popular at the same time as transistor radios. Parents found that purchasing a small transistor radio was a way for children to listen to their music without using the family tube radio.
The first transistor radio is often incorrectly attributed to Sony (originally Tokyo Tsushin Kogyo), which released the TR-55 in 1955. However, it was predated by the Regency TR-1, made by the Regency Division of I.D.E.A. (Industrial Development Engineering Associates) of Indianapolis, Indiana, which was the first practical transistor radio.
This made Sony the first company to produce commercial transistor radios from the ground up. American company Regency had launched their Regency TR-1 transistor radio earlier in 1954, but bought the transistors from Texas Instruments. Printed circuit boards were used, which was unusual for the time. [6] [8] [3]
The Regency TR-1, which used Texas Instruments' NPN transistors, was the world's first commercially produced transistor radio in 1954. Size: 3×5×1.25 inch (7.6×12.7×3.2 cm) Following development of transistor technology, bipolar junction transistors led to the development of the transistor radio.
VEF Spidola (Latvian: VEF Spīdola, Russian: ВЭФ Спидола) was the first mass-produced transistor radio with short wave band in the Soviet Union (tube short wave receivers were produced for many years before). It was manufactured by the VEF factory in Riga, Latvia, since 1962.
Their first product was a vacuum tube radio released in 1955, [3] [4] and their first transistor radio was the KR-6TS-1 radio released in the spring of 1957 [5] [6] at the price of 14,000 yen. [7] Through the 1960s, Koyo had manufactured and sold millions of portable transistor radios, particularly, their best-selling model KTR-624 had been ...
English: An early transistor pocket radio by Motorola. The first Motorola brand automobile radio was produced in 1930. Motorola began the commercial production of transistors at a new $1.5 million facility in Phoenix in 1955. This advertisement is from the May 23, 1960 issue of Life magazine (page 13).
