In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. In 1860 the U.S. Congress arranged among the telegraph companies a competition to create a national line. The winner was Western Union. In 1935, Western Union has put into operation first intercity fax communication. In 1866, Sibley ordered the engineers to develop a Western Union telegraph system of stock quotes in real time. Separation of the companies had two objectives: first, to give Western Union the opportunity to develop more intensively, and secondly, to help First Data to return to its original activity (in 1992 the company separated from the payment system of American Express as an independent financial services company). Money transfer is a matter of minutes, at any distance. 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. Western Union for more than 130 years provides money transfer services to its customers. Western Union made so that the time in all of American civil services was the same.
