Alcatel-Lucent 1947, John Bardeen, Walter Brattain, William Shockley of Bell Labs invented the transistor. In 1956, they received a Nobel Prize for their invention. The transistor led to an electronics revolution during the post-war boom. The transition from vacuum tubes to transistors enabled all technologies to be built on a smaller scale and use less electricity. Items that before required large dedicated spaces, could now fit into a home or even on a kitchen counter. In 1954, Gerald Pearson, Darryl Chapin and Calvin Fuller invented the solar cell. Telstar, the first active communications satellite also developed by Bell Labs and launched
Invention of the integrated circuit ahead in the revenue: 32% of the IC market in 1964 compared to 18% of Fairchild. The above logic ICs were built from standard components, with sizes and configurations defined by the technological process, and all the diodes and transistors on one IC were of the same type. The use of different transistor types was first proposed by Tom Long at Sylvania in 1961–1962. In late 1962, Sylvania launched the first family of transistor-transistor logic (TTL) ICs, which became a commercial success. Bob Widlar from Fairchild made a similar breakthrough in 1964–1965 in analog ICs (operational amplifiers). In 1959–1961 years,
