The development of information technology   The key technology in micro-electronics was the transistor, invented in 1947 at Bell  Laboratories in Murray Hill, New Jersey, by three physicists, Bardeen, Brattain,  and Shockley, who were later awarded the Nobel Prize. Other key technologies were  the use of silicon as a medium (1954) and the integrated circuit (1957). Together  these three made the development of semi conductors and microchips possible, and  the price of these dropped very rapidly in the years that followed (85% between 1959  and 1962, and from $50 dollars for an integrated circuit in 1962 to $1 in 1971). The  microprocessor chip was invented by Ted Hoff of Intel in 1971, and these gradually  became more and more powerful.    Computers really began with the first general purpose computer, the ENIAC  (Electronic Numerical Integrator and Calculator) in 1946. This was a huge monster,  weighing 30 tons and consuming enormous quantities of electricity. Many of the  early computers were made by business machine companies, most of which went out  of business as the new specialist computer companies appeared, and much of the
