When was the transistor first used?

1947
John Bardeen, Walter Brattain and William Shockley invented the first working transistors at Bell Labs, the point-contact transistor in 1947. Shockley introduced the improved bipolar junction transistor in 1948, which entered production in the early 1950s and led to the first widespread use of transistors.

Why was the transistor invented?

The transistor, aka point-contact transistor, is a semiconductor device that can amplify or switch electrical signals. It was developed to replace vacuum tubes. Vacuum tubes were bulky, unreliable and consumed too much power. So AT’s research-and-development arm, Bell Labs, started a project to find an alternative.

In which decade was the transistor invented?

The first practically implemented device was a point-contact transistor invented in 1947 by American physicists John Bardeen, Walter Brattain, and William Shockley. The transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things.

What came before the transistor?

Devices that performed the function of transistors had been around for 30–40 years prior to the invention of the transistor. They were called vacuum tubes. The vacuum tube triode was patented in 1907 and was the key invention that enabled the development of radio, television, and computers.

The three physicists who invented the transistor; William Shockley, John Bardeen, and Walter Brattain were awarded with the Nobel Prize.

What is the electronic age?

The electronic age is also known as the information age or the digital age. It began around the 1970s and continued till the present day. This is a period of transition from traditional industry to an economy based on information computerization.

Who made the first transistor?

What came before transistors?

Can we live without transistors?

No transistors, no computers capable of providing the type of function and economics we have today for anything depending on computers. And that means farming and food would more resemble 100–200 years ago. Well we could live without any modern technology if we had not choice.
