In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. Western Union offers one of the easiest ways for families and friends to send money and stay connected almost anywhere in the world. In the early 60s Western Union has put into operation transcontinental microwave system of data transmission via radio waves, completely replacing the web of telegraph poles and wires. 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 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.
