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 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.
