The limits  of available technology and then the First World War brought an end to  the experiments. Eight years later AT&amp;T again demonstrated the  feasibility of telephone calls between Europe and the United States by  sending a speech signal from New York to New Southgate in London.<\/p>\n<p>At  that time the General Post Office (GPO) managed the British telephone  system and its head, the Postmaster-General, was so impressed with the  demonstration that he decided to cooperate with AT&amp;T and the Western  Electric Company to create a commercial transatlantic telephone service  using radio signals. The GPO built a 200 kilowatt transmitter at the  Post Office Station at Rugby and experiments began to improve  transmission to such a point that it was commercially viable.  Furthermore the telephone network infrastructure in Britain and the  United States required substantial development.<\/p>\n<p>In February 1926,  the engineers achieved two-way voice communication between the two  radio stations and a month later journalists gathered at the trunk  exchanges in London and New York to take part in a demonstration of  two-way voice communication. Finally, on 7th January 1927, the service  opened with a call between Sir Evelyn Murray, the Secretary of the GPO  and Walter S. Gifford, the president of AT&amp;T, followed by calls  between those subscribers who had booked calls for that day.<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>The earliest attempt at transatlantic telephony was in 1915 when the American Telephone and Telegraph Company (later known as AT&amp;T) managed to transmit one-way voice signal between the Naval Wireless Station in Arlington, Virginia and the Eiffel Tower in Paris.
