The TR-63 was the first transistor radio to sell in the millions, leading to the mass-market penetration of transistor radios. [26] The TR-63 went on to sell seven million units worldwide by the mid-1960s. [27] With the visible success of the TR-63, Japanese competitors such as Toshiba and Sharp Corporation joined the market. By 1959, in the ...
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.
The all-transistor car radio was a $150 option. [51] [52] [53] The Sony TR-63, released in 1957, was the first mass-produced transistor radio, leading to the mass-market penetration of transistor radios. [54] The TR-63 went on to sell seven million units worldwide by the mid-1960s. [55]
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.
The Sony TR-63, released in 1957, was the first mass-produced transistor radio, leading to the widespread adoption of transistor radios. [44] Seven million TR-63s were sold worldwide by the mid-1960s. [45] Sony's success with transistor radios led to transistors replacing vacuum tubes as the dominant electronic technology in the late 1950s. [46]
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]
A very wide range of products was marketed under the Realistic brand. These included record players, stereo receivers, cassette decks, ham radios, [3] musical synthesizers and a few quadraphonic receivers and shortwave radios. Regency TR-1 – the first commercially manufactured transistor radio, it was introduced in 1954. Despite mediocre ...
Although Regency is credited of building and marketing the first Transistor Radio (Model TR-1 in 1954), Raytheon was only a few months behind with the 8TP1 through 4 "lunchbox" style radio. Norman Krim was involved in the early transistor radio designs.
