SATURDAY, JULY 9: TRANSISTOR
Profile America -- Saturday, July 9th. One of the most important inventions of our times was announced this week by Bell Laboratories in New Jersey -- the transfer resistance device -- far better known as the transistor. The small, simple and tough transistor replaced fragile, bulky and heat-generating vacuum tubes, which had been the heart of electronics for decades. The discovery led to the development of the integrated circuit and the microprocessor that are the basis of modern electronics. Today, transistor technology makes possible the devices we take for granted in daily life, as well as satellites and medical equipment. Making semiconductors and other components for electronics is a $123 billion a year business in the U.S. Profile America is in its 15th year as a public service of the U.S. Census Bureau.
