What was the first transistor radio?
Regency TR-1
In July 1954 the Texas Instruments and Industrial Development Engineering Associates (I.D.E.A.) companies embarked on a six month project to produce a pocket-sized radio for the Christmas market. The result was the Regency TR-1, the world’s first pocket transistor radio.
Who made the first transistor radio?
Texas Instruments
Transistor radio/Inventors
When were transistor radios first sold?
1954
Following the invention of the transistor in 1947—which revolutionized the field of consumer electronics by introducing small but powerful, convenient hand-held devices—the Regency TR-1 was released in 1954 becoming the first commercial transistor radio.
Which company invented transistor radio in 1952?
Transistors were first produced commercially by the American company Raytheon, in 1952. The first radio to be produced commercially was the Regency TR-1, which was also manufactured in America and went on sale in November 1954. It only used four Texas Instruments transistors, as transistors were then very expensive.
When did transistor radios come to Australia?
By 1957 transistor radios were being mass-produced in Japan. Australians were enthusiastic consumers of transistor portables imported or made locally, the local pioneer being AWA with its factory in Ashfield, Sydney. AWA’s first transistor radio was the Transistor 7 (897P) released in November 1957.
When was the first radio invented?
1890s
The Development of Radio Italian inventor Guglielmo Marconi (pictured at right) first developed the idea of a radio, or wireless telegraph, in the 1890s. His ideas took shape in 1895 when he sent a wireless Morse Code message to a source more than a kilometer away.
Who invented transistor in 1947?
1947: John Bardeen and Walter Brattain, with support from colleague William Shockley, demonstrate the transistor at Bell Laboratories in Murray Hill, New Jersey. It’s been called the most important invention of the 20th century.
Who invented transistor radio 1954?
One goal was to find a replacement for fragile and energy-wasting vacuum tubes. Building on war-time research, John Bardeen and Walter Brattain, working with group leader William Shockley, developed a device they called a transistor.
Who founded Sony?
Akio Morita
Masaru Ibuka
Sony Corporation/Founders
Originally known as Tokyo Tsushin Kogyo KK (the Tokyo Telecommunications Engineering Corporation), the company was founded by physicists Masaru Ibuka and Akio Morita. The company got its first break in the early 1950s when it received a license from Bell Labs to build transistors.
