Another invention of Western Union - time synchronization. In the early 60s Western Union has put into operation transcontinental microwave system of data transmission via radio waves, completely replacing the web of telegraph poles and wires. The size of the commission fee for the transfer is charged according to the Western Union tariffs and depends on the amount of money sent. In 1933, by the Western Union Company were invented "singing telegrams". In 1849, Selden and Sibley, the founders of the future Western Union, created the New York State Printing Telegraph Company. Transaction with Fexco has allowed Western Union to control directly more than 10 thousand points of service, which belonged to Fexco in 7 European countries (Spain, UK, Sweden, Ireland, Denmark, Norway and Finland). In 1884 Western Union has become a joint-stock company and was brought to the stock exchange. The company has entered in the first American stock index Dow Jones.
