In May 1954, Texas Instruments (TI), previously a producer of instrumentation for the oil industry [2] and locating devices for the US Navy, wanted an established radio manufacturer to develop and market a radio using TI's transistors. No major radio maker, including RCA, Philco, and Emerson, was interested. Previous vacuum tube-based pocket ...
In 1954, Texas Instruments designed and manufactured the first transistor radio. The Regency TR-1 used germanium transistors, as silicon transistors were much more expensive at the time. This was an effort by Haggerty to increase market demand for transistors.
Why Texas Instruments decided to put the first transistor radio on the market by Christmas 1954 and how it was accomplished." IEEE Spectrum, December 1985, pages 64–69; Transistor Radios: 1954–1968 (Schiffer Book for Collectors) by Norman R. Smith; Unique books on Transistor Radios by Eric Wrobbel
Texas Instruments had demonstrated all-transistor AM radios as early as 1952, but their performance was well below that of equivalent vacuum tube models. A workable all-transistor radio was demonstrated in August 1953 at the Düsseldorf Radio Fair by the German firm Intermetall. It was built with four of Intermetall's hand-made transistors ...
Under his leadership, the company grew from a small Texas oil exploration company into a global leader in the semiconductor industry. During his tenure, TI invested in transistors when their commercial value was still much in question, created the first silicon transistor , the first commercial transistor radio , the first integrated circuit ...
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.
Teal joined Bell Labs in 1930 and would remain employed there for 22 years. [1] During his time there, he continued to work with germanium and silicon. [1] When William Shockley's group at Bell Labs invented the transistor in 1947, Teal realized that substantial improvements in the device would result if it was fabricated using a single crystal, rather than the polycrystalline material then ...
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]
