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 Regency TR-1 was announced on October 18, 1954, by the Regency Division of I.D.E.A., was put on sale in November 1954 and was the first practical transistor radio made in any significant numbers. [13]
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.
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 ...
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.
1954: Regency introduced a pocket transistor radio, the TR-1, powered by a "standard 22.5V Battery". 1960: Sony introduced their first transistorized radio, small enough to fit in a vest pocket, and able to be powered by a small battery. It was durable, because there were no tubes to burn out.
The BBC’s iconic 1995 TV adaptation of Jane Austen’s Pride and Prejudice reportedly cost roughly £1 million per episode (about $9.6 million) to make. And it shows. The attention to period ...
Listening habits changed in the 1960s due to the introduction of the revolutionary transistor radio (Regency TR-1, the first transistor radio released December 1954), which was made possible by the invention of the transistor in 1948. (The transistor was invented at Bell labs and released in June 1948.)
