In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. 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 1914 Western Union engineers invented the first payment card - a prototype of the modern credit card. Thanks to cooperation with Western Union the Associated Press at the end of the XIX century took almost monopolistic position in the U.S. market news.
