Leaving the idea of expansion into Europe, Western Union took up the expansion of services in the U.S. market. In 1866, Sibley ordered the engineers to develop a Western Union telegraph system of stock quotes in real time. July 3, 1884 the company's shares were included in the calculation base for the newly created stock index Dow Jones Transportation Average. The Western Union Company uses the most up to date technologies and its unique worldwide computer network that allows to carry out quick money transfers payments in more than 190 countries around the world. 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.
