In 1920, Western Union has implemented the world's first transmission of images over the ocean. Most service points of Western Union work in the time convenient for customers throughout the week and throughout the year. In 1866, Sibley ordered the engineers to develop a Western Union telegraph system of stock quotes in real time. 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. 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.
