Happy birthday, transistor! The first transistor””the building block of today’s digital world, and the basis of Intel’s phenomenal success””was demonstrated at Bell Labs on December 16, 1947.
Fact: If the price of cars had dropped as fast over the last 60 years as the price of transistors, a new car today would cost about one U.S. cent.
Fact: The first transistor radio in 1954 contained four transistors. The latest chips contain 820 million transistors.
Fact: The first transistors, built in 1947, were large enough to hold in your hand. The latest-generation transistors are so small that 30 million of them could fit on the head of a pin.
