In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. In 1860 the U.S. Congress arranged among the telegraph companies a competition to create a national line. The winner was Western Union. Western Union has several divisions, with products such as person-to-person money transfer, money orders, business payments and commercial services. July 3, 1884 the company's shares were included in the calculation base for the newly created stock index Dow Jones Transportation Average. In October 2006 the company made an initial public offering of shares on the New York Stock Exchange, becoming independent from First Data company. The Western Union Company uses the most up to date technologies and its unique worldwide computer network that allows to carry out quick money transfers payments in more than 190 countries around the world. 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.
