In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. 1980 - for the first time in the history of Western Union revenues from money transfers exceeded the income from the telegraph service. In 1860 the U.S. Congress arranged among the telegraph companies a competition to create a national line. The winner was Western Union. Leaving the idea of expansion into Europe, Western Union took up the expansion of services in the U.S. market. Another invention of Western Union - time synchronization. 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). In October 1871 the company has implemented the world's first telegraph money order. After a century money transfers have become a major source of income for Western Union. Sibley, the founder of Western Union, did not build a new telegraph lines, and persuaded the other players to join. American Telegraph Company, however, still had to buy it.
