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. July 3, 1884 the company's shares were included in the calculation base for the newly created stock index Dow Jones Transportation Average. In 1933, by the Western Union Company were invented "singing telegrams". In the summer of 1990 top managers of the Western Union Company spent day and night in the main office in Englewood (Colorado, USA). They needed to meet the challenge: to save the Western Union from bankruptcy, paying off the debts of the company millions of dollars. Western Union made so that the time in all of American civil services was the same. 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.
