The success of transistor radios led to transistors replacing vacuum tubes as the dominant electronic technology in the late 1950s. [28] The transistor radio went on to become the most popular electronic communication device of the 1960s and 1970s. Billions of transistor radios are estimated to have been sold worldwide between the 1950s and ...
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 which used Texas Instruments' NPN transistors, was the world's first commercially produced transistor radio. Prototypes of all-transistor AM radio receivers were demonstrated, but were really only laboratory curiosities. However, in 1950 Shockley developed a radically different type of solid-state amplifier which became known ...
When the TR-55 was released in Japan in August 1955, [3] it was the first transistor radio marketed in that country. The TR-55 featured the Sony name, but the company did not officially change its name to Sony until January 1958. [4]
Prior to the emergence of television as the dominant entertainment medium in the 1950s, families gathered to listen to the home radio in the evening. The Golden Age of Radio, also known as the old-time radio (OTR) era, was an era of radio in the United States where it was the dominant electronic home entertainment medium.
The rocket radio was also used as an emergency radio, because it did not require batteries or an AC outlet. The rocket radio was available in several rocket styles, as well as other styles that featured the same basic circuit. [38] Transistor radios had become available at the time, but were expensive. Once those radios dropped in price, the ...
The RCA model R7 Superette superheterodyne table radio. This is a list of notable radios, which encompasses specific models and brands of radio transmitters, receivers and transceivers, both actively manufactured and defunct, including receivers, two-way radios, citizens band radios, shortwave radios, ham radios, scanners, weather radios and airband and marine VHF radios.
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.
