The Western Union Company - the American company, specialising on granting of services of monetary intermediary. Western Union was founded in 1851. The company is one of leaders in the market of the international remittances. Another invention of Western Union - time synchronization. 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. 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 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 1991, Western Union has sold some low-profit division of the company AT & T, GM Hughes Electronics, and to some others. In the same year the company changed its name to New Valley Corp. Sibley, the founder of Western Union, did not build a new telegraph lines, and persuaded the other players to join. American Telegraph Company, however, still had to buy it.
