RCA Electronic Music is the first synthesizer prior to the creation of artificial electronic sounds. 1952 Reintroduction of regular television broadcasts in Germany after the Second World War. 20th Century Fox developed with "Cinemascope" the most successful wide-screen process to better compete with television. Only some 50 years later pulls ...
The word electronics began to be used in the 1940s [4] In the late 1950s, the term electronics engineering started to emerge. Electronic laboratories ( Bell Labs , for instance) created and subsidized by large corporations in the industries of radio, television, and telephone equipment, began churning out a series of electronic advances.
The first in 1885 was a low voltage system in Bözingen, [39] and the first high voltage system went into service in 1889 in Genoa, Italy, by the Acquedotto de Ferrari-Galliera company. This system transmitted 630 kW at 14 kV DC over a circuit 120 km long.
Electromagnets were then used in the first practical engineering application of electricity by William Fothergill Cooke and Charles Wheatstone who co-developed a telegraph system that used a number of needles on a board which were moved to point to letters of the alphabet. A five needle system was used initially, but was given up as too expensive.
The first planar monolithic integrated circuit (IC) chip was demonstrated in 1960. The idea of integrating electronic circuits into a single device was born when the German physicist and engineer Werner Jacobi developed and patented the first known integrated transistor amplifier in 1949 and the British radio engineer Geoffrey Dummer proposed to integrate a variety of standard electronic ...
Experimental equipment that he built in 1934 went into operation 5 years later, converting a portion of the telephone exchange network into an electronic data processing system, using thousands of vacuum tubes. [59] In the US, in 1940 Arthur Dickinson (IBM) invented the first digital electronic computer. [88]

Electronic engineering is a sub-discipline of electrical engineering that emerged in the early 20th century and is distinguished by the additional use of active components such as semiconductor devices to amplify and control electric current flow. Previously electrical engineering only used passive devices such as mechanical switches, resistors ...
