Key takeaways

  • International broadcasting belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect International broadcasting to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of International broadcasting from memory before moving on to harder problems.

Reference excerpt

International broadcasting consists of radio and television transmissions that purposefully cross international boundaries, often with then intent of allowing expatriates to remain in touch with their countries of origin as well as educate, inform, and influence residents of foreign countries. Content can range from overt propaganda and counterpropaganda to cultural content to news reports that reflect the point of view and concerns of the originating country or that seek to provide alternative information to that otherwise available as well as promote tourism and trade. In the first half of the twentieth century, international broadcasting was used by colonial empires as a means of connecting colonies with the metropole (for example the BBC Empire Service as well as France's Poste Colonial and the Dutch overseas radio services, PCJJ and PHOHI). When operated by governments or entities close to a government, international broadcasting can be a form of soft power. Less frequently, international broadcasting has been undertaken for commercial purposes by private broadcasters. 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. In the early 2020's, many of the public international broadcasters that court audiences abroad have seen their budgets shrink, with the exception of Deutsche Welle, while state media outlets from authoritarian countries like Russia, China and Iran have been increasing their budgets since the early 2000's.

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 its 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 and became the world's longest-running shortwave programme, continuing until 1995, transferring to Radio Netherlands after World War II. 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.

Worked examples

Example 1 — a first encounter with International broadcasting

Start with the simplest possible case. Write down what International broadcasting claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to International broadcasting before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about International broadcasting ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of International broadcasting

In research
International broadcasting appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses International broadcasting in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
International broadcasting is common in secondary-school and first-year university syllabi. It links to neighbouring topics International broadcasting, Propaganda techniques, so understanding it makes those chapters shorter.
In everyday life
Look for International broadcasting outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
