In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. In 1866, Sibley ordered the engineers to develop a Western Union telegraph system of stock quotes in real time. 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. 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). Payment systems are one of basic elements of infrastructure of e-commerce. The Western Union Company is a leader in global payment services 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.
