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. In 1860 the U.S. Congress arranged among the telegraph companies a competition to create a national line. The winner was Western Union. One of the common kinds of money transfer is a transfer via the international system of Western Union. In 2000 was launched the Web site westernunion.com, with which users from certain countries can independently transfer funds online. Western Union made so that the time in all of American civil services was the same.
