The telegraph system was the first form of instant communication. It was invented by Samuel Morse (USA). The first link, from Washington DC to Baltimore Maryland, USA, was completed by May 1844. The first message was sent by Morse himself and read 'What Hath God Wrought!'. The arrangements of dots and dashes became known as Morse Code.
