Leaving the idea of expansion into Europe, Western Union took up the expansion of services in the U.S. market. 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. One of the common kinds of money transfer is a transfer via the international system of Western Union. 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. Western Union provides consumers and businesses with fast, reliable and convenient ways to send and receive money around the world, to send payments and to purchase money orders. 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.
