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 1914 Western Union engineers invented the first payment card - a prototype of the modern credit card. 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.
