In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. In April 1851 companions registered in Albany New York and Mississippi Valley Printing Telegraph Company (NYMVPTC), which included founded two years before New York State Printing Telegraph Company. In 1995, First Financial Management was acquired by First Data Corp. (the deal amounted to $ 7 billion), and Western Union Financial Services became a subsidiary of First Data. 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. In 1849, Selden and Sibley, the founders of the future Western Union, created the New York State Printing Telegraph Company. Western Union made so that the time in all of American civil services was the same.
