==== Formative years ====
Australian [[Amateur radio operator|radio hams]] can be traced to the early 1900s. The 1905 ''Wireless Telegraphy Act''<ref>{{cite web|url=http://www.comlaw.gov.au/Details/C2004C07914|title=Wireless Telegraphy Act 190|website=Australian Federal Register of Legislation}}</ref> whilst acknowledging the existence of wireless telegraphy, brought all broadcasting matters in Australia under the control of the Federal Government.<ref name="Australia, R.R. Walker 1973">{{cite book|first=R.R.|last=Walker|year=1973|title=The Magic Spark – 50 Years of Radio in Australia|location=Melbourne|url=https://www.worldradiohistory.com/BOOKSHELF-ARH/History/The-Magic-Spark-1973-Walker.pdf|isbn=0725601167}}</ref> In 1906, the first official [[Morse code]] transmission in Australia was by the [[Marconi Company]] between [[Queenscliff, Victoria]] and [[Devonport, Tasmania]].<ref>{{cite web | url=https://insidestory.org.au/when-marconis-magic-came-to-queenscliff/ | title=When Marconi's magic came to Queenscliff… • Inside Story | date=12 August 2010 }}</ref>

==== Experiments with broadcasting music ====
The first broadcast of music was made during a demonstration on 13 August 1919 by [[Ernest Fisk]] (later Sir Ernest) of AWA – [[Amalgamated Wireless (Australasia)]].  A number of amateurs commenced broadcasting music in 1920 and 1921.<ref name="ReferenceA"/> Many other amateurs soon followed. 2CM was run by Charles MacLuran who started the station in 1921 with regular Sunday evening broadcasts from the Wentworth Hotel, Sydney. 2CM is often regarded as Australia's first, regular, non-official station.<ref name="ReferenceA"/><ref>{{cite web|url=http://bpadula.tripod.com/australiashortwave/id34.html|title=1923 - Evolution of Australian Domestic Radio|website=bpadula.tripod.com|access-date=26 March 2018}}</ref>

==== Sealed set system ====
It was not until November 1923 when the government finally gave its approval for a number of officially recognised [[medium wave]] stations.<ref name="ReferenceA"/><ref name="Australia, R.R. Walker 1973"/>
All stations operated under a unique [[Sealed Set]] system under which each set was sealed to the frequency of one station. Part of the price of the set went to the government via the [[Postmaster-General's Department]] (PMG), with money also going to the broadcaster.  Apart from extremely limited advertising, this was the broadcasters' only source of income.  From the outset problems with the system came to the fore. Many young people built their own sets, which could receive all the stations.<ref name="Australia, R.R. Walker 1973"/>

==== Categories in Australia from 1924 ====
As quickly as July 1924, the Sealed Set system was declared to be unsuccessful and it was replaced by a system of A Class and B Class stations.  There were one or two A Class stations in each major market and these were paid for by a listener's licence fee imposed on all listeners-in. The five former sealed set stations became A Class stations, and they were soon joined by stations in other State capitals.<ref name="Australia, R.R. Walker 1973"/>

This photo was taken in earlier days when Voight was a prominent British athlete, and winner of the [[Olympic medal|Gold Medal]] for the five mile race at the [[1908 Summer Olympics]] in London.]]

Amateur broadcasters continued to operate in the [[long wave]] and [[short wave]] bands.<ref name="ReferenceA"/>

A national service, the [[Australian Broadcasting Corporation|Australian Broadcasting Commission]], was formed in July 1932, when the Australian Broadcasting Company's contract expired.<ref name="ReferenceD"/>

==== Early experiments with television ====
As early as 1929, two Melbourne commercial radio stations, [[3UZ]] and [[KIIS 101.1|3DB]] were conducting experimental mechanical television broadcasts – these were conducted in the early hours of the morning, after the stations had officially closed down. In 1934 Valentine McDowall conducted experiments in electronic television.<ref>{{cite web|first=F.|last=Schubert|url=https://www.racp.edu.au/page/library/college-roll/college-roll-detail%26id%3D496|archive-url=https://web.archive.org/web/20150504062337/https://www.racp.edu.au/page/library/college-roll/college-roll-detail%26id%3D496|archive-date=2015-05-04|title=College Roll: McDowall, Valentine|publisher=The Royal Australasian College of Physicians}}</ref> at amateur station [[4CM]] Brisbane<ref>{{cite web|url=https://espace.library.uq.edu.au/view/UQ:212637/s00855804_1961_1962_6_4_750.pdf|title=eSpace - The University of Queensland|website=espace.library.uq.edu.au|access-date=26 March 2018}}</ref>

==== Mobile stations ====
Two of Australia's most unusual medium wave stations were mobile stations 2XT and 3YB. They both operated in eras prior to the universal establishment of rural radio stations. 2XT was designed and operated by AWA within the State of [[New South Wales]], from a [[New South Wales Government Railways|NSW Railways]] train, between November 1925 and December 1927. 2XT, which stood for ''experimental train'', visited over 100 rural centres. Engineers would set up a transmitting aerial and the station would then begin broadcasting.  This led to the further sales of AWA products. 3YB provided a similar service in rural [[Victoria (Australia)|Victoria]] between October 1931 and November 1935. Initially, the station operated from a [[Ford Motor Company|Ford]] car and a Ford truck, but from 17 October 1932 they operated from a converted 1899 former Royal Train carriage. Whilst the engineers were setting up the station's 50-watt transmitter in the town being visited, salesmen would sign up advertisers for the fortnight that 3YB would broadcast from that region. The station was on the air from 6.00 and 10.00 pm daily, and its 1,000-record library was divided into set four-hour programs, one for each of 14 days. In other words, the music broadcast from each town was identical. The station was operated by Vic Dinenny, but named after announcer Jack '''Y'''oung from '''B'''allarat. On 18 January 1936, Dinenny set up [[3YB]] [[Warrnambool]], followed on 18 May 1937 by [[3GG|3UL]] [[Warragul]].<ref name="ReferenceA"/><ref name="ReferenceD"/>

The [[merchant vessel]] [[HMAS Kanimbla (C78)|MV ''Kanimbla'']] is believed to be the world's only ship built with an inbuilt broadcasting station. The Kanimbla was constructed in Northern Ireland in 1936 and was primarily designed for [[McIlwraith, McEacharn & Co]] to ply passengers between [[Cairns]] and [[Fremantle]]. The broadcasting station was constructed and operated by [[Amalgamated Wireless (Australasia)|AWA]] and was initially given the [[Amateur radio|ham radio]] callsign VK9MI but was later 9MI. (At this time, the "9" in the callsign was aberrationary [see "Call Signs, above].) The station made an experimental broadcast before leaving Northern Ireland, and a number of such broadcasts at sea, on the way to Australia. 9MI's first official broadcast in April 1939 was made from the [[Great Australian Bight]].<ref name="ReferenceD"/> The station broadcast on [[short wave]], usually a couple of times per week, but many of its programs were relayed to commercial medium wave stations that were also owned by AWA. The 9MI manager and announcer (and probably the only member of staff) was Eileen Foley.<ref>{{Cite web |url=http://www.offshore-radio.de/HansKnot/female.htm|publisher=offshore-radio.de |title=Female Offshore Radio Deejays |access-date=2015-04-12 |archive-url=https://web.archive.org/web/20040811095008/http://www.offshore-radio.de/HansKnot/female.htm |archive-date=2004-08-11 |url-status=dead }}</ref> 9MI ceased broadcasting at the commencement of World War II in September 1939. The Kanimbla was commissioned as a [[Royal Navy]] (later [[Royal Australian Navy]]) vessel with the name HMS/HMAS Kanimbla.  It had an extremely prominent and successful war-time career.<ref>{{Cite web |url=http://www.broadcasting-fleet.com/kanimbla.htm |title=S.S.

=== Canada ===
{{Main|History of broadcasting in Canada}}
The history of broadcasting in Canada begins as early as 1919 with the first experimental broadcast programs in Montreal. The Canadians were swept up in the radio craze and built crystal sets to listen to American stations while The Marconi Wireless Telegraph Company of Canada offered its first commercially produced radio-broadcast receiver (Model "C") in 1921, followed by its "Marconiphone" Model I in 1923. Main themes in the history include the development of the engineering  technology; the construction of stations across the country and the building of networks; the widespread purchase and use of radio and television sets by the general public; debates regarding state versus private ownership of stations; financing of the broadcasts media through the government, license fees, and advertising; the changing content of the programming; the impact of the programming on Canadian identity; the media's influence on shaping audience responses to music, sports and politics; the role of the Québec government; Francophone versus Anglophone cultural tastes; the role of other ethnic groups and First Nations; fears of American cultural imperialism via the airwaves; and the impact of the Internet and smartphones on traditional broadcasting media.<ref>{{cite book|first=Robert|last=Armstrong|title=Broadcasting Policy in Canada|date=January 2010 |publisher=University of Toronto Press |isbn=9781442610354}}</ref><ref>{{cite book|first=Marc|last=Raboy|title=Missed Opportunities: The Story of Canada's Broadcasting Policy|year=1990|publisher=McGill-Queen's Press - MQUP |isbn=978-0773507753}}</ref>

Radio signals carried long distances, and a number of American stations could easily be received in parts of Canada.  The first Canadian station was CFCF, originally an experimental station from the Marconi Company in Montreal.<ref>{{cite book|first=Mary|last=Vipond|title=Listening In: The First Decade of Canadian Broadcasting 1922-1932|publisher=McGill-Queen's University Press|year=1992|isbn=9780773509177}}</ref> Civilian use of Wireless Telegraphy had been forbidden in Canada for the duration of World War I. The Marconi Wireless Telegraph Company of Canada was the only one to retain the right to continue radio experiments for military use.  This proved instrumental in giving the company a lead in developing an experimental radio broadcasting station immediately after the war. The first radio broadcast in Canada was accomplished by The Marconi Wireless Telegraph Company of Canada in Montreal on December 1, 1919 under the call sign XWA (for "Experimental Wireless Apparatus") from its Williams Street factory. The station began regular programming on May 20, 1920 and its call letters were changed to CFCF on November 4, 1920.<ref>{{cite book|last=Murray|first=R.P.|title=The Early Development of Radio in Canada, 1901-1930: An Illustrated History|year=2005|publisher=Sonoran |isbn=978-1886606203}}</ref> In Toronto, the first radio station was operated by the ''Toronto Star'' newspaper.  Station CKCE began in April 1922 and was so well received that the Star pushed forward with its own studios and transmitting facilities, returning to the air as CFCA in late June 1922.  In Montreal, another newspaper, ''La Presse'', put its own station, CKAC on the air in late September 1922.  Because there were governmental limitations on radio frequencies back then, CKAC and CFCF alternated—one would broadcast one night, and the other would broadcast the night after that.<ref>{{cite web|url=http://www.broadcasting-history.ca/timeline/index2.php?url=/listings_and_histories/radio/histories.php?id=495&historyID=246|title=Canadian Communications Foundation History of CKAC Radio|website=broadcasting-history.ca|access-date=26 March 2018|archive-url=https://web.archive.org/web/20160422211234/http://www.broadcasting-history.ca/timeline/index2.php?url=%2Flistings_and_histories%2Fradio%2Fhistories.php%3Fid%3D495&historyID=246|archive-date=22 April 2016|url-status=dead}}</ref>

As radio grew in popularity during the mid-1920s, a problem arose:  the U.S. stations dominated the airwaves and with a limited number of frequencies available for broadcasters to use, it was the American stations that seemed to get most of them. This was despite an agreement with the US Department of Commerce (which supervised broadcasting in the years prior to the Federal Radio Commission) that a certain number of frequencies were reserved exclusively for Canadian signals. But if a US station wanted one of those frequencies, the Department of Commerce seemed unwilling to stop it, much to the frustration of Canadian owners who wanted to put stations on the air. The Canadian government and the US government began negotiations in late 1926, in hopes of finding a satisfactory solution.<ref>{{cite news|title=Canada Radio Fans Fight Interference|newspaper=Tampa (FL) Tribune|date=January 16, 1927|page=12D}}</ref>  Meanwhile, in 1928, Canada got its first network, operated by the Canadian National Railways. CNR had already made itself known in radio since 1923, thanks in large part to the leadership of CNR's president, Sir Henry Thornton. The company began equipping its trains with radio receivers, and allowed passengers to hear radio stations from Canada and the US. In 1924, CN began building its own stations, and by 1928, it was able to create a network.<ref>{{cite web|url=http://www.broadcasting-history.ca/timeline/index2.php?url=http://www.broadcasting-history.ca/networks/networks_CNR.html|title=Canada's First Network.|website=broadcasting-history.ca|access-date=26 March 2018|archive-url=https://web.archive.org/web/20160304030330/http://www.broadcasting-history.ca/timeline/index2.php?url=http%3A%2F%2Fwww.broadcasting-history.ca%2Fnetworks%2Fnetworks_CNR.html|archive-date=4 March 2016|url-status=dead}}</ref>

=== Cuba ===
There was interest in radio almost from broadcasting's earliest days. Due to the proximity of Cuba to the U.S. state of Florida, some Cubans would try to listen to the American stations whose signals reached the island. But there was no radio station in Cuba until 1922.  The arrival of the first radio station, PWX, was greeted with enthusiasm.<ref>{{cite news|title=Cuban Mill Hands Like Radio Jazz|newspaper=Boston Herald|date=April 1, 1923|page=12D}}</ref> PWX, owned by the Cuban Telephone Company, was located in Havana.  It was a joint venture with the International Telephone and Telegraph Company of New York.  PWX debuted on the air on October 10, 1922.<ref>{{cite journal|title=Broadcasting at Havana, Cuba|journal=Radio Magazine|date=February 1923|volume=5|issue=2|page=33}}</ref>  PWX broadcast programs in both English and Spanish, and its signal was easily received at night in a number of American cities.<ref>{{cite journal|title=The Voice from PWX|journal=Winston-Salem (NC) Journal|date=September 21, 1924|page=3}}</ref> Another early station in Cuba was owned by Frank Jones, an American amateur radio operator and Chief Engineer of the Tuinucu Sugar Company.  The station used amateur call letters, and went on the air as 6KW.<ref>{{cite news|title=Cuban City Enjoys Free Radio Concert|newspaper=Springfield Sunday Union and Republican|date=March 27, 1927|page=11C}}</ref> In late 1928, PWX began using the call letters CMC.

=== France ===
{{Main|Radio France}}
[[Radio Paris]] began operations in 1922, followed by Radio Toulouse and Radio Lyon. Before 1940, 14 commercial and 12 public sector radio stations were in operation. The government exerted tight control over radio broadcasting. Political debate was discouraged; for example, in the 1932 election campaign, the opposition was allowed one broadcast while the incumbent made numerous campaign broadcasts.<ref>{{cite book|first=Paul|last=Starr|year=2004|title=The Creation of the Media: Political Origins of Modern Communications|publisher=Basic Books|page=376|isbn=978-0465081943}}</ref> France lagged behind other European countries in consumer ownership of radio sets, with 5 million radio receivers in 1937, compared to over 8 million in both Britain and Germany and 26 million in the United States. The government imposed very strict controls on the dissemination of news. After 1938, stations were allowed only three brief bulletins of seven minutes each per day to cover the day's news. The Prime Minister's office closely supervised the news items that were to be broadcast. Due to these policies, French citizens learned little or nothing of the events surrounding the lead-up to World War II from the radio. As a result, the French population was often puzzled about the specifics of current events, and their morale and support for government policies was much weaker than in Britain, where news broadcasts were used to communicate regularly with citizens.<ref>{{cite book|first=Anthony|last=Adamthwaite|year=1995|title=Grandeur and Misery: France's Bid for Power in Europe 1914-1940|publisher=Bloomsbury Academic|pages=177–78|isbn=9780713165760}}</ref>

=== Germany ===
[[File:Ferdinand_Braun.jpg|100px|thumb|right|[[Ferdinand Braun]]]]
Ferdinand Braun's major contributions were the introduction of a closed tuned circuit in the generating part of the transmitter, and its separation from the radiating part (the antenna) by means of inductive coupling, and later on the usage of crystals for receiving purposes. Braun experimented at first at the University of Strasbourg. Braun had written extensively on wireless subjects and was well known through his many contributions to the Electrician and other scientific journals.<ref name=Wireless>[https://books.google.com/books?id=DEfOAAAAMAAJ&pg=PA709 "Dr. Braun, Famous German Scientist, Dead"], ''The Wireless Age'' (volume 5), June 1918,  pp. 709–10</ref> In 1899, he would apply for the patents, ''Electro telegraphy by means of condensers and induction coils'' and ''Wireless electro transmission of signals over surfaces''.<ref>[https://books.google.com/books?id=9LPmAAAAMAAJ&pg=PA159 "Provisional Patents, 1899"], ''The Electrical Engineer'' (volume 23) February 3, 1899, p. 159.</ref> Braun invented the [[phased array]] antenna, which led to the development of [[radar]], [[smart antennas]], and [[MIMO]], in 1905<ref>{{cite web | url=https://www.britannica.com/biography/Ferdinand-Braun | title=Ferdinand Braun &#124; Nobel Prize, Telegraphy, Radio &#124; Britannica }}</ref> and shared the 1909 Nobel Prize in Physics with Marconi "for their contributions to the development of wireless telegraphy".<ref>{{Cite web |title=The Nobel Prize in Physics 1909|url=https://www.nobelprize.org/prizes/physics/1909/summary/ |publisher=[[NobelPrize.org]]|language=en|url-status=live|date=2023|access-date=31 July 2023|archive-date=31 July 2023|archive-url=https://archive.today/20230731180825/https://www.nobelprize.org/prizes/physics/1909/summary/}}</ref><!--[[User:Kvng/RTH]]-->
The first civilian radio broadcast in Germany was a Christmas concert on December 22, 1920.<ref>{{Cite web|publisher=mdr.de|title=Vor 100 Jahren: Erste Radiosendung in Deutschland |url=https://www.mdr.de/zeitreise/hundert-jahre-radio-jubilaeum-geburtstag-100.html|access-date=2020-12-22|website=www.mdr.de|language=de}}</ref> While its reception was confirmed from all over Europe, reception in Germany was still a punishable offense, as a result of the [[Treaty of Versailles]].<ref>{{Cite web|title=Weihnachtskonzert für Schwarzhörer|url=https://www.deutschlandfunk.de/weihnachtskonzert-fuer-schwarzhoerer.761.de.html?dram:article_id=114006|access-date=2020-12-22|website=Deutschlandfunk| date=22 December 2007 |language=de-DE}}</ref>

The first radio station in Germany went on the air in Berlin in late 1923, using the call letters "LP."<ref name="Now Numbers Many Millions 1923, p. 13"/> Before 1933, German radio broadcasting was conducted by 10 regional broadcasting monopolies, each of which had a government representative on its board. The Post Office provided overall supervision.  A listening fee of {{Reichsmark|2|link=yes}} per receiver paid most costs, and radio station frequencies were limited, which restricted the number of amateur radio operators. Immediately following Hitler's assumption of power in 1933, [[Joseph Goebbels]] became head of the Ministry for [[Propaganda]] and Public Enlightenment and took full control of regulating and overseeing broadcasting. Non-Nazis were removed from broadcasting and editorial positions, and Jews were fired from all positions.<ref>{{cite journal|author=Adelheid von Saldern|title=Volk and Heimat Culture in Radio Broadcasting during the Period of Transition from Weimar to Nazi Germany|journal=The Journal of Modern History|volume=76|issue=2|year=2004|pages=312–346|doi=10.1086/422932|s2cid=143001813}}</ref>

Germany was easily served by a number of European mediumwave stations, including the [[BBC]], but the Nazis made it illegal for Germans to listen to foreign broadcasts. During the war, German stations broadcast war propaganda and entertainment for German forces dispersed through Europe, as well as air raid alerts. There was heavy use of short wave for "Germany Calling" programmes directed at Britain and Allied forces around the world. Goebbels also set up numerous Nazi stations that pretended to be from the Allied world.<ref>{{cite book|isbn=9780300067095|first1=Horst J.P.|last1=Bergmeier|first2=Rainer E.|last2=Lotz |year=1997|title=Hitler's airwaves: the inside story of Nazi radio broadcasting and propaganda swing|publisher=Yale University Press|url=https://books.google.com/books?id=1Z0_EAAAQBAJ}}</ref>

=== Japan ===
The first radio station in Japan was JOAK, which opened in Tokyo in March 1925.  It was founded by Masajiro Kotamura, an inventor and engineer. It was unique in that at least one of its announcers was a woman, Akiko Midorikawa.<ref>{{cite news|title=Station JOAK of Japan|newspaper=Boston Herald|date=April 11, 1926|page=6}}</ref> JOAK was followed soon after by JOBK in Osaka and JOCK in Nagoya.  The National Broadcasting Service, today known as NHK (Nippon Hoso Kyokai), began in August 1926. All stations were supported by licensing fees:  in 1926, for example, people wishing to receive a permit to own a radio set paid a fee of one yen a month to the government.<ref>{{cite news|url=https://pugetsound.media/pictures/Radio%20Expo%20page%2018.pdf|archive-url=https://web.archive.org/web/20181002232717/http://www.pugetsound.media/pictures/Radio%20Expo%20page%2018.pdf|url-status=dead|archive-date=October 2, 2018|title=Japan Hides Radio Artists|newspaper=Seattle Daily Times|date=September 7, 1927|page=K4}}</ref> Programming on Japanese stations of the 1920s included music, news, language instruction (lessons were offered in English, French and German) and education talks. These early stations broadcast on average about eight hours of programs a day.<ref>{{cite news|first=Carl H.|last=Butman|title=Nippon Keeps Tight Grip on Radio|newspaper=Springfield Republican|date=September 11, 1927|page=6C}}</ref>

=== Mexico ===
Amateur radio was very popular in Mexico; while most of the hams were male, notably Constantino de Tarnava, acknowledged in some sources as Mexico's first amateur radio operator,<ref>{{cite book|first=Marvin|last=Alinsky|year=1988|title=International Handbook of Broadcasting Systems|publisher=Greenwood Press|page=215|isbn=9780313243486}}</ref> one of the early ham radio operators was female—Maria Dolores Estrada.<ref>"Mexican Girl Gets First Grade Commercial License." QST, January 1917, p. 49.</ref> But commercial radio broadcasting was difficult to achieve, due to a federal regulation forbidding any broadcasts that were not for the benefit of the Mexican government. Still, in November 1923, CYL in Mexico City went on the air, featuring music (both folk songs and popular dance concerts), religious services, and news. CYL used as its slogans "El Universal" and "La Casa del Radio", and it won over the government by giving political candidates the opportunity to use the station to campaign.<ref>{{cite journal|first=Susan|last=Haymes|title=A Junket to the Mexico City Studios of CYL|journal=Radio Digest|date=November 14, 1925|pages=7, 12}}</ref> Its signal was so powerful that it could sometimes be received in Canada.<ref>{{cite news|title=Novel Programs from CYL Mexico|newspaper=Toronto Globe|date=December 9, 1925|page=9}}</ref> Pressure from listeners and potential station owners also contributed to the government relenting and allowing more stations to go on the air.<ref>{{cite book|first=Marvin|last=Alinsky|year=1988|title=International Handbook of Broadcasting Systems|publisher=Greenwood Press|page=216|isbn=9780313243486}}</ref> In 1931, the "C" call letters were all changed to "X" call letters (XE being reserved for broadcasting), and by 1932, Mexico had nearly forty radio stations, ten of which were in Mexico City.<ref name="Cuban and Mexican Broadcasters"/>

=== Philippines ===
Interest in amateur radio was noted in the Philippines in the early 1920s.<ref>{{cite news|title=Signals Heard by Island|newspaper=Portland Oregonian|date=March 15, 1925|page=9}}</ref>  There were radio stations operating in the Philippines, including one owned by American businessman named Henry Hermann, as early as 1922, according to some sources; not much documentation about that period of time exists.  In the autumn of 1927, KZRM in Manila, owned by the Radio Corporation of the Philippines, went on the air.<ref>{{cite news|title=Manila Goes on the Air to Entertain the Orient|newspaper=New York Times|date=October 2, 1927|page=XX18|url=https://www.nytimes.com/1927/10/02/archives/manila-goes-on-the-air-to-entertain-the-orient-waves-of-kzrm-spread.html}}</ref> The Radio Corporation of the Philippines was a subsidiary of American company RCA (Radio Corporation of America).<ref>{{cite news|url=https://www.nytimes.com/1927/02/13/archives/to-open-manila-studio-radio-corporation-subsidiary-will-operate.html|title=To Open Manila Studio|newspaper=The New York Times|date=February 13, 1927|page=E18}}</ref> By 1932, the island had three radio stations: KRZC in Cebu, as well as KZIB (owned by a department store) and KZFM, the government-owned station in Manila. Of the stations listed by Pierre Key, KZFM was the strongest, with 50,000 watts.<ref>Pierre Key's Radio Annual, 1933 edition, pp. 269-270.</ref>  Two radio networks were ultimately created:  one, the Manila Broadcasting Company, began as a single station, KZRH in Manila, in July 1939, and after World War II, in 1946, the station's owners began to develop their network by buying other radio properties. As for the Philippine Broadcasting Company, it too began with one station (KZFM), and received its new name in mid-1946, after the Philippines became an independent country. At the end of 1946, the new network had six stations.<ref>{{cite journal|title=KZPI Power Will Go to 10 KW on January 1|journal=Broadcasting Magazine|date=December 16, 1946|page=30}}</ref>  Both KZRH and KZFM also affiliated with American networks; the stations wanted to have access to certain popular American programs, and the American networks wanted to sell products in the Philippines.<ref>{{cite journal|title=Advertisement for KZRH: The Voice of the Philippines|journal=Broadcasting Magazine|date=December 16, 1946|page=55}}</ref>

=== Sri Lanka ===
[[Sri Lanka]] has the oldest radio station in Asia and the second oldest in the world, known as [[Radio Ceylon]]. It is now known as the [[Sri Lanka Broadcasting Corporation]]. Sri Lanka created [[broadcasting]] history in Asia when broadcasting was started in Ceylon by the Telegraph Department in 1923 on an experimental footing, just three years after the inauguration of broadcasting in Europe. Gramophone music was broadcast from a tiny room in the Central Telegraph Office with the aid of a small transmitter built by Telegraph Department engineers using the radio equipment of a captured German submarine.<ref name="Transmitter">{{cite web|title=For that Old Magic (Frontline Magazine, India)|url=http://www.flonnet.com/fl2301/stories/20060127001908700.htm|access-date=2008-09-04|url-status=dead|archive-url=https://web.archive.org/web/20080918024249/http://www.flonnet.com/fl2301/stories/20060127001908700.htm|archive-date=2008-09-18}}</ref>

The first experimental music broadcasts, from [[Guglielmo Marconi|Marconi's]] factory in [[Chelmsford, England|Chelmsford]], began in 1920. Two years later, in October 1922, a consortium of radio manufacturers formed the [[British Broadcasting Company]] (BBC); they allowed some sponsored programs, although they were not what we would today consider a fully commercial station.  Meanwhile, the first radio stations in England were experimental station [[2MT]], located near Chelmsford, and station [[2LO]] in London:  both were operated by the Marconi Company.  By late 1923, there were six stations broadcasting regularly in the United Kingdom: London's 2LO, [[Manchester|Manchester's]] [[2ZY]], and stations in [[Birmingham]] ([[5IT]]), [[Cardiff]], [[Newcastle upon Tyne|Newcastle]], and [[Glasgow]].<ref name="Now Numbers Many Millions 1923, p. 13">{{cite news|title=Radio Audience Now Numbers Many Millions|newspaper=Springfield Republican|date=September 30, 1923|page=13}}</ref>  As for the consortium of radio manufacturers, it dissolved in 1926, when its license expired; it then became the [[British Broadcasting Corporation]], a non-commercial organization. Its governors are appointed by the British government, but they do not answer to it. Lord [[John Charles Walsham Reith|Reith]] took a formative role in developing the BBC, especially in radio.<ref name="Lord Reith">{{cite news |title=News article on Lord Reith in The Guardian Newspaper, London|url=https://www.theguardian.com/media/2003/jul/07/mediatop100200361|access-date=2008-10-13 | date=2003-07-07}}</ref>

[[Radio 2XG|Pioneer radio station 2XG]], also known as the "Highbridge station", was an experimental station located in New York City and licensed to the DeForest Radio Telephone and Telegraph Company. It was the first station to use a [[vacuum tube]] transmitter to make radio broadcasts on a regular schedule.  From 1912 to 1917 [[Charles Herrold]] made regular broadcasts, but used an [[arc transmitter]]. He switched to a vacuum tube transmitter when he restarted broadcasting activities in 1921. Herrold coined the terms [[broadcasting]] and [[narrowcasting]].<ref name="broadcasting">{{cite web|title=Radio Broadcasting is Born|url=http://www.dcwstore.com/console-radios-and-tv.htm|access-date=2008-10-13|archive-url=https://web.archive.org/web/20081204063825/http://www.dcwstore.com/console-radios-and-tv.htm|archive-date=2008-12-04|url-status=dead}}</ref> Herrold claimed the invention of broadcasting to a wide audience, through the use of antennas designed to radiate signals in all directions.

A few organizations were allowed to keep working on radio during the war.  [[Westinghouse Electric Corporation|Westinghouse]] was the most well-known of these.  [[Frank Conrad]], a Westinghouse engineer, had been making transmissions from 8XK since 1916 that included music programming.<ref name="Frank Conrad">{{cite web |title=Frank Conrad The Father of Commercial Broadcasting |website=[[Institute of Electrical and Electronics Engineers]] (IEEE) |url=http://www.ieee.org/web/aboutus/history_center/biography/conrad.html|access-date=2008-10-13|archive-url=https://web.archive.org/web/20080403021152/http://www.ieee.org/web/aboutus/history_center/biography/conrad.html|archive-date=2008-04-03}}</ref> A team at the [[University of Wisconsin–Madison]] headed by Professor [[Earle M.

====1920s====
By 1919, after the war, radio pioneers across the country resumed transmissions.  The early stations gained new call signs.  A few early stations, notably 8MK (later known as WWJ in Detroit) were started by newspapers, but in those early years, radio and newspapers regarded each other as competitors. One early station, 8XK in Pittsburgh, became [[KDKA (AM)|KDKA]] in 1920; its ownership has asserted that it was the first radio station in the US, but that claim is controversial <ref>{{cite web|first=Donna|last=Halper|date=July 2020|url=https://www.thebdr.net/when-broadcasting-really-began-refuting-the-kdka-myth-again/|title=When Broadcasting Really Began|website=The Broadcasters' Desktop Resource}}</ref>

Madison Avenue early on recognized the importance of radio as a new advertising medium. Advertising provided the major funding for most stations. The United States never had a licensing fee for set users.<ref>{{cite book|first=Susan|last=Smulyan|year=1994|title=Selling radio: The commercialization of American broadcasting, 1920-1934|publisher=Smithsonian Inst Press|isbn=9781560983125 |url=https://books.google.com/books?id=eXe4AAAAIAAJ}}</ref>

Radio in education began as early as April 1922, when Medford Hillside's WGI Radio broadcast the first of an ongoing series of educational lectures from Tufts College professors.  These lectures were described by the press as a sort of "wireless college."<ref>{{cite news|title=Tufts College to Give Radio Lecture Course|newspaper=Olympia (WA) Daily Recorder|date=March 25, 1922|page=5}}</ref>  Soon, other colleges across the U.S. began adding radio broadcasting courses to their curricula; some, like the University of Iowa, even provided what today would be known as distance-learning credits.<ref>{{cite news|title=U of I Offers Full Credits in Air School|newspaper=Rockford (IL) Daily Register|date=October 5, 1925|page=4}}</ref> [[Curry College]], first in Boston and then in Milton, Massachusetts, introduced one of the nation's first broadcasting majors in 1932 when the college teamed up with WLOE in Boston to have students broadcast programs.  This success led to numerous radio courses in the curriculum which has taught thousands of radio broadcasters from the 1930s to today.<ref>{{cite web|url=http://www.curry.edu|title=Curry College - Home|website=www.curry.edu|access-date=26 March 2018}}</ref>

By 1931, a majority of U.S. households owned at least one [[radio receiver]].<ref>{{cite journal|last=Craig|first=Steve|year=2004|title=How America Adopted Radio: Demographic Differences in Set Ownership Reported in the 1930–1950 U.S. Censuses|journal=[[Journal of Broadcasting & Electronic Media]]|volume=48|issue=2|pages=179–195|publisher=[[Routledge]]|doi=10.1207/s15506878jobem4802_2|s2cid=145186571|url=https://www.researchgate.net/publication/233149747}}</ref> In 1934, several independent stations formed the [[Mutual Broadcasting System]] to exchange syndicated programming, including ''[[The Lone Ranger]]'' and ''[[Amos 'n' Andy]]''. Prior to 1927, U.S. radio was supervised by the Department of Commerce.  Then, the Radio Act of 1927 created the Federal Radio Commission (FRC);<ref>{{cite journal|title=The Radio Act|journal=Central Law Journal|date=March 4, 1927| page=158 | url=https://books.google.com/books?id=GW8tAAAAIAAJ&pg=PA158}}</ref> in 1934, this agency became known as the Federal Communications Commission (FCC). A [[Federal Communications Commission]] decision in 1939 required [[NBC]] to divest itself of its [[Blue Network]].  That decision was sustained by the Supreme Court in a 1943 decision, National Broadcasting Co. v. United States, which established the framework that the "scarcity" of radio-frequency meant that broadcasting was subject to greater regulation than other media. This [[Blue Network]] network became the [[American Broadcasting Company]] (ABC). Around 1946, ABC, NBC, and CBS began regular television broadcasts. Another TV network, the [[DuMont Television Network]], was founded earlier, but was disbanded in 1956; later in 1986 the surviving DuMont independent stations formed the nucleus of the new [[Fox Broadcasting Company]].<ref name="DTNHWS">{{cite web|url=https://dumonthistory.com/9.html|title=DuMont Television Network Historical Web Site|archive-url=https://web.archive.org/web/20101027143941/https://dumonthistory.com/9.html |archive-date=2010-10-27 }}</ref>
