International broadcasting, in a limited extent, began during World War I, when German and British stations broadcast press communiqués using Morse code. With the severing of Germany's undersea cables, the wireless telegraph station in Nauen was the country's sole means of long-distance communication.
The US Navy Radio Service radio station in New Brunswick, Canada, transmitted the 'Fourteen Points' by wireless to Nauen in 1917. In turn, Nauen station broadcast the news of the abdication of Kaiser Wilhelm II on November 10, 1918.
History
Origins
Guglielmo Marconi pioneered the use of short wave radio for long-distance transmissions in the early 1920s. Using a system of parabolic reflector antennae, Marconi's assistant, Charles Samuel Franklin, rigged up a large antenna at Poldhu Wireless Station, Cornwall, running on 25 kW of power. In June and July 1923, wireless transmissions were completed during nights on 97 meters from Poldhu to Marconi's yacht Elettra in the Cape Verde Islands. High speed shortwave telegraphy circuits were then installed from London to Australia, India, South Africa and Canada as the main element of the Imperial Wireless Chain from 1926.
The Dutch began conducting experiments in the shortwave frequencies in 1925 from Eindhoven. The radio station PCJJ began the first international broadcasting on March 11, 1927 with programmes in Dutch for colonies in the Dutch West Indies and Dutch East Indies and in German, Spanish and English for the rest of the world. The popular Happy Station show was inaugurated in 1928.
In 1927, Marconi also turned his attention toward long distance broadcasting on shortwave. His first such broadcasts took place to commemorate Armistice Day in the same year. He continued running a regular international broadcast that was picked up around the world, with programming from the 2LO station, then run by the BBC. The success of this operation caught the BBC's attention who rented out a shortwave transmitting station in Chelmsford, with the callsign G5SW, to Marconi. The BBC Empire Service was finally inaugurated on December 19, 1932, with transmissions aimed towards Australia and New Zealand.
Expansion
Other notable early international broadcasters included Vatican Radio (February 12, 1931), Radio Moscow, the official service of the Soviet Union (renamed the Voice of Russia, following the collapse of the Soviet Union). Clarence W. Jones started transmitting on Christmas Day, 1931 from Christian missionary radio station HCJB in Quito, Ecuador. Broadcasting in South Asia was launched in 1925 in Ceylon - Radio Ceylon, now the Sri Lanka Broadcasting Corporation is the oldest in the region.
Shortwave broadcasting from Nauen in Germany to the US, Central and South America, and the Far East began in 1926. A second station, Zeesen, was added in 1931. In January 1932, the German Reichspost assumed control of the Nauen station and added to its shortwave and longwave capacity. Once Adolf Hitler assumed power in 1933, shortwave, under the Auslandsrundfunk (Foreign Radio Section), was regarded as a vital element of Nazi propaganda.
German shortwave hours were increased from two hours a day to 18 per day, and eventually twelve languages were broadcast on a 24-hour basis, including English. A 100 kilowatt transmitter and antenna complex was built at Zeesen, near Berlin. Specialty target programming to the United States began in 1933, to South Africa, South America, and East Asia in 1934, and South Asia and Central America in 1938. German propaganda was organized under Joseph Goebbels, and played a key role in the German annexation of Austria and the Munich Crisis of 1938.
In 1936, the International Radio Union recognized Vatican Radio as a "special case" and authorized its broadcasting without any geographical limits. On December 25, 1937, a Telefunken 25-kW transmitter and two directional antennas were added. Vatican Radio broadcast over 10 frequencies.
During the Spanish Civil War, the Nationalist forces received a powerful Telefunken transmitter as a gift of Nazi Germany to aid their propaganda efforts, and until 1943 Radio Nacional de España collaborated with the Axis powers to retransmit in Spanish news from the official radio stations of Germany and Italy.
World War II
During the Second World War, Russian, German, British, and Italian international broadcasting services expanded. In 1942, the United States initiated its international broadcasting service, the Voice of America. In the Pacific theater, General Douglas MacArthur used shortwave radio to keep in touch with the citizens of the Japanese-occupied Philippine Islands.
