In the Western Union in the 30s of the 20th century worked 14 thousand couriers delivering telegrams. In 1860 the U.S. Congress arranged among the telegraph companies a competition to create a national line. The winner was Western Union. 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 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.
