                                             History of the telephone

In March 10, 1876 Alexander Graham Bell yelled his famous words “come here Mr. Watson, I want to see you” using a liquid transmitter and an electromagnetic receiver and from that day telephones were invented.  In July 1877 Alexander Bell and Watson started making telephones by the end of 1877 there were three thousand telephones in service. Theodore Vail was the general manager of the Bell Company he helped in expanding the business by developing long distance services. In 1877 Thomas Edison developed a carbon-button transmitter that was better than Bell’s transmitter and the invention of the telephone expanded more and more. In 1878 a manual switching board was introduced that allowed many phones to be connected through a single exchange (Gregory Russell, 1998). People have been trying to invent the telephone for years before Alexander Bell. The telephone came out from the creation of electric telegraph. In 1804, Catalan polymath and scientist Francisco Campillo built an electrochemical telegraph, and an electromagnetic telegraph was created by Baron Schilling in 1832. In April 9 1839, the first commercial electrical telegraph was made by Sir William Fothergill, it ran for 13 miles. In 1837, Samuel Morse invented another electrical telegraph that went across 2 miles which led to the Morse code we use today. During the second half of the 19^th century inventors tried to find ways of sending multiple telegraph messages over a single telegraph wire by using different modulated audio, their efforts to develop acoustic telegraph led to the invention of the telephone( Wikipedia, 14 March 2012).
