The most important Cold War invention was the transistor (in 1945), which led to the Integrated Circuit. The world of today is largely shaped by the applications of semiconductors. The transistor made the computer possible. One of the first computer built was the ENIAC (1946) used 19,000 vacuum tubes, consumed 150 kilowatts of power and rarely worked continuously for more than an hour without needing repairs. The transistor revolutionized the reliability, size and utility of electronic equipment. The value of computers was recognized quickly and the first supercomputer, the CRAY-1 was commissioned in 1976. The CRAY-1 was seven feet tall and nine feet wide, and was powered from its own electrical substation. However, this monster had less computing power than the average PC of today.
