In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. The Western Union Company is a financial services and communications company based in the United States. 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. In 1884 Western Union has become a joint-stock company and was brought to the stock exchange. The company has entered in the first American stock index Dow Jones.
