In the Western Union in the 30s of the 20th century worked 14 thousand couriers delivering telegrams. In 1866, Sibley ordered the engineers to develop a Western Union telegraph system of stock quotes in real time. 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). In October 2006 the company made an initial public offering of shares on the New York Stock Exchange, becoming independent from First Data company. In 1914 Western Union engineers invented the first payment card - a prototype of the modern credit card. In 1879 Western Union left the telephone business after losing a lawsuit against Alexander Graham Bell - the patent holder on the phone.
