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.

[126] [b] 4000 BC: Oldest evidence of locks, the earliest example discovered in the ruins of Nineveh, the capital of ancient Assyria. [129] 4000 BC – 3400 BC: Oldest evidence of wheels, found in the countries of Ukraine, Poland, and Germany. [130 ...
The first working transistor, a germanium-based point-contact transistor, was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, [31] followed by the bipolar junction transistor in 1948.
Vacuum tubes remained the preferred amplifying device for 40 years, until researchers working for William Shockley at Bell Labs invented the transistor in 1947. In the following years, transistors made small portable radios, or transistor radios, possible as well as allowing more powerful mainframe computers to be built. Transistors were ...
The MOSFET made it possible to build high-density integrated circuit chips. [58] The earliest experimental MOS IC chip to be fabricated was built by Fred Heiman and Steven Hofstein at RCA Laboratories in 1962. [61] MOS technology enabled Moore's law, the doubling of transistors on an IC chip every two years, predicted by Gordon Moore in 1965. [62]
