The History of the Television

25 March 1925 is when the Scot John Logie Baird gave the first demonstration of television in a London shopping centre. On 2 October of the same year Baird transmitted moving images over a distance with a wide range of greys commonly called black and white TV.
Baird’s television was called electromechanical because the shooting and the viewing equipment were based on an electromechanical device invented in 1883 by Paul Gottlieb Nipkow, called the Nipkow disc.
The television became famous only in some world countries, it was not known in Italy and in 1939 it was replaced by the electronic television. The electronic television was created on 7 September 1927 by the American Philo Farnsworth and was named in this way because both the shooting and the vision apparati were created with an electronic device, the cathode ray tube, invented by the German physicist Ferdinand Braun in 1897. The first broadcast tests in Italy were televised in 1934 and in 1949 Corrado presented an experimental transmission. Regular service, however, only started on 3 January 1954 in black and white by RAI.
