Slowly centralized in the early 1930s, radio fell under Nazi control in 1933, causing the somewhat varied programming of independent German stations to quickly give way to a more national service by the mid-1930s. Considerable time was given to commentary and speeches by <a href="https://www.britannica.com/biography/Adolf-Hitler" class="md-crosslink autoxref " data-show-preview="true">Adolf Hitler</a> and other leaders, although stations also broadcast shows devoted to regional culture and traditions, as well as several music programs that tended to feature German composers.

Modern short-wave transmitters operated from Zeesen, near Berlin. As Germany occupied more of Europe in 1940–42, additional stations came under German control. For example, when German forces occupied Luxembourg in 1940, the popular commercial short-wave station there became part of Nazi propaganda (ironically serving the long-held desire of the <a href="https://www.britannica.com/money/British-Broadcasting-Corporation" class="md-crosslink autoxref " data-show-preview="true">BBC</a> to close down its competition for British listeners).</p><!--[MOD4]--><span class="marker MOD4 mod-inline"></span> <!--[PREMOD5]--><span class="marker PREMOD5 mod-inline"></span><p class="topic-paragraph">As one part of the German approach, a new kind of traitor was featured over the air: “Lord Haw-haw” broadcast German propaganda to the British for the entire war.

Private, advertiser-supported stations were also expanding across the country at about this time; there were soon a dozen of them. (The French began external broadcasting in 1931, primarily to expatriates in their extensive colonies in Africa and Southeast Asia.) Only in 1933 did French listeners begin to pay an annual license fee to listen to radio, the funds going only to government stations. Political parties played an important role in French radio, with listenership divided about equally between government and private stations. Although the private stations (some <a class="md-dictionary-link md-dictionary-tt-off mw" data-term="affiliated" href="https://www.merriam-webster.com/dictionary/affiliated" data-type="MW">affiliated</a> with major newspapers) carried advertising, they had to submit to considerable government control regarding programming decisions. Gradually, news on French stations grew more slanted to match the views of a particular political party; as a result, the government established in 1936 an objective national network newscast originating from Paris that all stations had to carry. Regional variance in music and cultural programs continued until the war and the period of German occupation (1940–44), at which point competition between public and private stations came to an end when the private stations were taken over by the central government.

Dozens of stations were operating by late in the decade, though few served rural areas or the Asian portion of the vast federation. Stations carried news provided by the government as well as a considerable number of music and cultural programs; there was virtually no <a href="https://www.britannica.com/science/light" class="md-crosslink autoxref " data-show-preview="true">light</a> entertainment. Regular international radio <a class="md-dictionary-link md-dictionary-tt-off eb" data-term="transmissions" href="https://www.britannica.com/dictionary/transmissions" data-type="EB">transmissions</a> from Russia began over Radio Moscow in 1929 with broadcasts in English, French, and German—some of the first multilingual broadcasts by any country. By the early 1930s the Soviet government was exerting tighter control over station operations and content (increasingly the Moscow station acted as the centre of an informal network) but also, perhaps ironically, providing more entertainment.</p><!--[MOD7]--><span class="marker MOD7 mod-inline"></span> <!--[PREMOD8]--><span class="marker PREMOD8 mod-inline"></span><p class="topic-paragraph">To make radio listening easier, the Soviet Union developed a system of wired radio—connecting inexpensive receivers to local stations by wire—that grew slowly throughout the 1930s and became more widespread than over-the-air radio. In 1928 there were only about 20 over-the-air stations, a number that grew to about 90 outlets and an estimated 760,000 over-the-air receivers by 1941.

Shanghai alone had 43 stations, many of them foreign owned, designed to service the thriving International Settlement. Most of China was covered by a Nanjing-based Central Broadcasting Station shortwave transmitter, installed in 1932. Inexpensive crystal radio receivers were widely used. Most programs on these early radio stations consisted of lectures and talks, some news, and <a href="https://www.britannica.com/art/Chinese-music" class="md-crosslink autoxref " data-show-preview="true">Chinese music</a>.

Programs of Indian music, drama, and public affairs were increasingly broadcast over AIR in Hindustani after about 1940, in an attempt to standardize language use in one of the most multilingual parts of the world.</p><!--[MOD11]--><span class="marker MOD11 mod-inline"></span></section> <section data-level="3" id="ref301752"><h2 class="h3"><span id="ref1123906"></span><a href="https://www.britannica.com/topic/history-of-Japan" class="md-crosslink ">Japan</a></h2> <!--[PREMOD12]--><span class="marker PREMOD12 mod-inline"></span><p class="topic-paragraph">Planning for Japanese radio was <a class="md-dictionary-link md-dictionary-tt-off eb" data-term="delayed" href="https://www.britannica.com/dictionary/delayed" data-type="EB">delayed</a> by the <a href="https://www.britannica.com/event/Tokyo-Yokohama-earthquake-of-1923" class="md-crosslink " data-show-preview="true">Tokyo-Yokohama earthquake of 1923</a>; transmissions did not get under way until two years later, allowing the country to refine its basic broadcast policies (based on the experience of other countries) before the first stations appeared.

Several other stations were added throughout the decade and into the 1930s.

NHK was increasingly controlled by military leadership after 1941 and became a news and propaganda outlet supporting Japanese war aims. Japan also captured many radio transmitters in occupied nations. A number of women were called <span id="ref1124005"></span>Tokyo Rose as they broadcast (in English) against the Allied military forces in the Pacific.

Programs were usually live and included news, variety, comedy, and considerable Brazilian music. To help support these early stations (in addition to their growing advertising revenue), radio clubs were formed, with donations given to the stations by the wealthy members. By 1940 recorded music and soap operas were popular (as they would continue to be in television), and commercial radio networks were developed, primarily by major newspapers. National and regional governments also established networks to serve sparsely populated regions of little interest to advertisers, especially the huge <a href="https://www.britannica.com/place/Amazon-Basin" class="md-crosslink autoxref " data-show-preview="true">Amazon basin</a>.</p><!--[MOD15]--><span class="marker MOD15 mod-inline"></span></section> <section data-level="3" id="ref301755"><h2 class="h3"><span id="ref1123908"></span><a href="https://www.britannica.com/topic/history-of-Mexico" class="md-crosslink ">Mexico</a></h2> <!--[PREMOD16]--><span class="marker PREMOD16 mod-inline"></span><p class="topic-paragraph">Mexican radio broadcasting began before <a href="https://www.britannica.com/topic/regulation" class="md-crosslink autoxref " data-show-preview="true">regulation</a> and more formal licensing appeared in 1926. By 1930 there were about 30 commercial and 10 government-operated stations, many of the latter being very vocal supporters of the still-young Mexican revolution. The Education Ministry operated its own station from 1925 to 1939, broadcasting cultural and educational programs from <a href="https://www.britannica.com/place/Mexico-City" class="md-crosslink autoxref " data-show-preview="true">Mexico City</a>. Outside the major cities, however, radio receiver ownership was limited, and much listening was <a class="md-dictionary-link md-dictionary-tt-off eb" data-term="done" href="https://www.britannica.com/dictionary/done" data-type="EB">done</a> on a community or group basis. Beginning in 1937, every station in the country had to carry the government-produced <em><span id="ref1124006"></span>La hora nacional</em> (“The National Hour”), which featured Mexican music, culture, history, and news. Political broadcasts were largely banned, while Mexican <em>música tipica</em> (“folk music”) was required in virtually all programs. Indeed, Mexican orchestral and <a href="https://www.britannica.com/art/vocal-music" class="md-crosslink autoxref " data-show-preview="true">vocal music</a> was widely heard throughout the country—more than 90 percent of the time on some stations—thus furthering appreciation of national culture.
