In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. In 1935, Western Union has put into operation first intercity fax communication. 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. In October 1871 the company has implemented the world's first telegraph money order. After a century money transfers have become a major source of income for Western Union. In 1933, by the Western Union Company were invented "singing telegrams".
