Leaving the idea of expansion into Europe, Western Union took up the expansion of services in the U.S. market. Each money transfer is protected with control number, that allows you to track and to ensure prompt payment of money specified by you person. 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 2007 the company made 167.7 million transactions on money transfers between individuals and 404.6 million transactions between physical and legal persons. 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. In 2000 was launched the Web site westernunion.com, with which users from certain countries can independently transfer funds online.
