The first transistor was successfully demonstrated on December 23, 1947, at Bell Laboratories in Murray Hill, New Jersey. Bell Labs was the research arm of American Telephone and Telegraph (AT&T). The three individuals credited with the invention of the transistor were William Shockley, John Bardeen and Walter Brattain. The introduction of the ...
A stylized replica of the point-contact transistor invented at Bell Labs on December 23, 1947. The point-contact transistor was the first type of transistor to be successfully demonstrated. It was developed by research scientists John Bardeen and Walter Brattain at Bell Laboratories in December 1947.
The bipolar junction transistor, the first type of transistor to be mass-produced, is a combination of two junction diodes and is formed of either a thin layer of p-type semiconductor sandwiched between two n-type semiconductors (an n–p–n transistor), or a thin layer of n-type semiconductor sandwiched between two p-type semiconductors (a p ...
Its roots can be traced to the invention of the transistor by Shockley, Brattain, and Bardeen at Bell Labs in 1948. [1] [2] Bell Labs licensed the technology for $25,000, [3] and soon many companies, including Motorola (1952), [4] Schockley Semiconductor (1955), Sylvania, Centralab, Fairchild Semiconductor and Texas Instruments were making ...
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.

The bipolar transistor was invented in 1947. From 1955 onward transistors replaced vacuum tubes in computer designs, [ 143 ] giving rise to the "second generation" of computers. Compared to vacuum tubes, transistors have many advantages: they are smaller, and require less power than vacuum tubes, so give off less heat.
The first practical transistor was the point-contact transistor, invented by the engineers Walter Houser Brattain and John Bardeen while working for William Shockley at Bell Labs in 1947. This was a breakthrough that laid the foundations for modern technology. [2] Shockley's research team also invented the bipolar junction transistor in 1952.
