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. 1980 - for the first time in the history of Western Union revenues from money transfers exceeded the income from the telegraph service. Each money transfer is protected with control number, that allows you to track and to ensure prompt payment of money specified by you person. 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.
