Leaving the idea of expansion into Europe, Western Union took up the expansion of services in the U.S. market. In 1877, starting from September, New York City residents began to have the opportunity to check the time on clock with the "time ball", located on the roof of constructed in the same year a new corporate headquarters - Western Union Building. 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 1864, fearing the laying of long underwater lines, Western Union offered to carry out laying of telegraph lines to Europe through the Russian Alaska under the narrow Bering Strait and then to Siberia with branching in the major cities of Europe. 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 1879 Western Union left the telephone business after losing a lawsuit against Alexander Graham Bell - the patent holder on the phone. In 2000 was launched the Web site westernunion.com, with which users from certain countries can independently transfer funds online.
