Transistors created a revolution in electronics.
    
Prior to the transistor, electronics relied on vacuum tubes. Vacuum tubes made possible very sophisticated electronics, including broadcast radio and television as we know them, radar, and the first electronic computers.

The transistor ushered in the "solid-state revolution," and another revolution called "miniaturization." Compared to tubes, transistors were at least a hundred times smaller, used a hundred times less power, and were extremely stable and reliable. At first, the transistor changed things in small ways. The book-sized portable radios that used small tubes were displaced by pocket-sized "transistor radios." Over time, transistors completely reshaped the way in which electronics could be used and the things that could be done with it.

A computer made out of transistors did not require continuous component replacement, and because of the stability of transistors it could be turned on and just start working properly within seconds. Transistorized circuits could withstand military conditions, in missiles for example, making electronic guidance systems much more feasible.
    
Originally "miniaturization" simply meant replacing light-bulb-sized tubes with jelly-bean-sized transistors. But a second breakthrough occurred in the 1960s, when engineers realized that the same technology used to create a single transistor on a semicondutor wafer could be used to create many interconnected transistors. Over time, engineers learned to put dozens, hundreds, thousand, and eventually millions of transistors onto a single chip, launching the "digital revolution."
