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 1877, starting from September, New York City residents began to have the opportunity to check the time on clock with the "time ball", located on the roof of constructed in the same year a new corporate headquarters - Western Union Building. 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. Money transfer is a matter of minutes, at any distance. To obtain the Golden card can any client of Western Union, committing money transfers on this system more than 1 time per year. Getting the card is issued at the time of making of the next transfer. In 1914 Western Union engineers invented the first payment card - a prototype of the modern credit card. Thanks to cooperation with Western Union the Associated Press at the end of the XIX century took almost monopolistic position in the U.S. market news. 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.
