1947: Point-contact transistor invented by American physicists John Bardeen, Walter Brattain, and William Shockley.
1954: The first working silicon transistor was developed at Bell Labs on January 26. First commercial silicon transistor was produced by Texas Instruments that same year.
1954: The first "production" pocket transistor radio was the Regency TR-1, released in October. Produced as a joint venture between the Regency Division of Industrial Development Engineering Associates, I.D.E.A. and Texas Instruments of Dallas Texas, It was a near pocket-sized radio featuring 4 transistors and one germanium diode. the TR-1 was manufactured in Indianapolis, Indiana.
1955: Chrysler announced that the new line of 1956 Chrysler and Imperial cars, would have the first transistor in dash radios replacing vacuum tube ones. The cars hit the dealership showroom floors on October 21.
1956: Bardeen, Brattain, and Shockley shared the Nobel Prize in Physics for their transistor achievement.
1960: The first MOSFET actually built at Bell Labs.
2SB54: The most commonly used audio frequency PNP transistor used in radios.
SC-72: a common "through hole" transistor.
3 BILLION: The amount of MOSFET transistors in an advanced microprocessor circa 2009.
60 MILLION: The amount of transistors built in 2002. for [each] man, woman, and child on Earth. https://twitter.com/cyberlineusa #Radio #Tech #Technology #CyberLine #CyberLineNet #MickWilliams #Internet #Scifi #CyberLineUSA See less
