There was no need for a shoulder bag or a Wi-Fi connection in a hotel room. By modern standards, tube-based computers were slow and enormously bulky. In fact, the term bug was coined when moths or other insects would light on the tubes and blow them out, according to Mike Feibus, an analyst at TechKnowledge Strategies Inc. It wasn't a very efficient technology, and required a lot of tubes and bulbs and heat to do basic mathematically calculations. The tube would be turned off for a zero, and on for a one. It's probably doubled from what it would have been without transistors."īefore transistors, vacuum tubes were turned on or off to represent zeros and ones. Four years later, parent company Western Electric announced it. Shockley, Bardeen and Brattain of Bell Laboratories. Look at the change in the productivity of the whole economy. The transistor was invented in 1948 by Drs. Look at transportation, computers, government, finance, manufacturing. "The invention of the transistor was probably the most important invention in the 20th century," said Risto Puhakka, president of VLSI Research Inc. That 10,000 times the number of ants on Earth.

Intel estimates that about 10 quintillion (or a 1 followed by 19 zeros) transistors ship each year.

Today, a 45-nanometer Penryn chip from Intel holds 820 million transistors.

It was powered by transistors and cost $3,995. introduced the first commercial mobile phone, the DynaTAC 800X.

Busicom introduced the first single-chip, pocket-size calculator, the LE-120A HANDY, in 1971.

Forty-two years later, Moore's Law still holds true. The first transistor was a startling moment of insight that led to a Nobel Prize.

Intel Corp.'s Gordon Moore in 1965 came up with what came to be known as Moore's Law, which stated that the number of transistors on a chip will double about every two years. Bell Labs’ invention of the point-contact transistor, in December 1947, is a case in point.

screen and used 23 silicon and germanium transistors. introduced the first portable, transistorized TV, the TV8-301, in 1960. The first transistor radio, the Regency TR-1, went on the market for $49.99 in 1954.

The first commercial device to use a transistor was the Sonotone 1010 hearing aid, created in 1953.The first transistor was about the size of the palm of a hand, with a depth of two matchbooks stacked on top of each other.

The PC and the Internet have been phenomena, but how usable and ubiquitous would they be without millions of tiny transistors running inside laptops, desktops and servers? Computer chips run inside our cars, cell phones and even tiny, implantable LoJack-like devices that help find lost pets. Transistors inside pacemakers keep our hearts going.

16, 1947, to be exact - the transistor was invented at Bell Labs, igniting a series of changes and advances that would change the way people listen to their favorite music, do their jobs, pay their bills, educate themselves and buy everything from books to used toaster ovens.
