The technology and practice of transmitting messages or information over distance using electrical signals through wires.
From electro- (Greek elektron, 'amber') + telegraphy (from Greek tele- 'distant' + graphia 'writing'). The term became established in the 19th century as telegraph technology developed.
Electrotelegraphy was so revolutionary that the telegraph operator became one of the first modern information workers—young people competed for these jobs because it represented the cutting edge of technology, much like computer programming did in the 20th century.
