In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. Each money transfer is protected with control number, that allows you to track and to ensure prompt payment of money specified by you person. 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. Payment systems are one of basic elements of infrastructure of e-commerce. In 2000 was launched the Web site westernunion.com, with which users from certain countries can independently transfer funds online. The first offices of company were located in the Reynolds Arcade building in Rochester, New York. The sign above the main entrance to the building - Western Union made so that the time in all of American civil services was the same.
