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 1920, Western Union has implemented the world's first transmission of images over the ocean. In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. Western Union offers one of the easiest ways for families and friends to send money and stay connected almost anywhere in the world. Leaving the idea of expansion into Europe, Western Union took up the expansion of services in the U.S. market. Another invention of Western Union - time synchronization. Money transfer is a matter of minutes, at any distance. 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. 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.
