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. July 3, 1884 the company's shares were included in the calculation base for the newly created stock index Dow Jones Transportation Average. In 1914 Western Union engineers invented the first payment card - a prototype of the modern credit card.
