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 1864, fearing the laying of long underwater lines, Western Union offered to carry out laying of telegraph lines to Europe through the Russian Alaska under the narrow Bering Strait and then to Siberia with branching in the major cities of Europe. 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. In 2000 was launched the Web site westernunion.com, with which users from certain countries can independently transfer funds online.
