In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. In 1920, Western Union has implemented the world's first transmission of images over the ocean. 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 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 the summer of 1990 top managers of the Western Union Company spent day and night in the main office in Englewood (Colorado, USA). They needed to meet the challenge: to save the Western Union from bankruptcy, paying off the debts of the company millions of dollars.
