In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. America was on the verge of civil war and needed a reliable connection between the North and South. On the telegraph market of the USA at this time were operated with six large companies: American Telegraph Company, New York Albany and Buffalo Electro-Magnetic Telegraph Company, Atlantic and Ohio Telegraph, Illinois & Mississippi Telegraph Company, New Orleans & Ohio Telegraph Company, and the brainchild of Sibley & Co. - The Western Union Telegraph. Western Union has several divisions, with products such as person-to-person money transfer, money orders, business payments and commercial services. The size of the commission fee for the transfer is charged according to the Western Union tariffs and depends on the amount of money sent. 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. Number of active holders of "Golden Card" of Western Union amounted to 9.5 million people worldwide. 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.
