125-521: Radio Ukraine International provides listeners with up-to-date information in a format of short podcasts. As of May 2024, RUI broadcasts in foreign languages can be heard daily starting at: Radio Ukraine International began operation in March 1992 as the first International broadcast station of independent Ukraine. Formally known as Radio Kiev, a "sister" station to Radio Moscow during the Soviet era. Interval signal

250-465: A "chain". The Radio Corporation of America (RCA), General Electric , and Westinghouse organized a competing network around its own flagship station, RCA's WJZ (now WABC) in New York City, but were hampered by AT&T's refusal to lease connecting lines or allow them to sell airtime. In 1926 AT&T sold its radio operations to RCA, which used them to form the nucleus of the new NBC network. By

375-841: A 10 shilling receiver license fee. Both highbrow and mass-appeal programmes were carried by the National and Regional networks. The period from the early 1920s through the 1940s is often called the "Golden Age of Radio". During this period AM radio was the main source of home entertainment, until it was replaced by television. For the first time entertainment was provided from outside the home, replacing traditional forms of entertainment such as oral storytelling and music from family members. New forms were created, including radio plays , mystery serials, soap operas , quiz shows , variety hours , situation comedies and children's shows . Radio news, including remote reporting, allowed listeners to be vicariously present at notable events. Radio greatly eased

500-962: A 24-hour schedule of news, interviews, discussion, and debate and is a World Media Partner with BBC World Service and is affiliated to IRN / SKY News . Talk Radio Europe broadcasts in FM on the Costa del Sol , Costa Almeria , Costa Blanca , and across the island of Mallorca in English. It is available on the Internet and all smartphone platforms. Talk radio in the United Kingdom is popular, though not as much as music radio. Nationwide talk stations include BBC Radio 4 , BBC Radio 5 Live , BBC Radio 4 Extra , Talkradio , Talksport and Times Radio . Regional stations include BBC Radio Scotland and BBC Radio Wales . Many BBC Local Radio stations and some commercial stations offer

625-584: A big Metromedia presence in Los Angeles. He sent Henry from New York to Los Angeles to turn KLAC into a success. The first thing that Henry did was hire the legendary morning team of Lohman and Barkley. Henry had built a strong relationship with programmer Jim Lightfoot, who had joined Henry in Miami. A unique opportunity presented itself when Joe Pyne, who had begun his career as a radio talk personality in Pennsylvania,

750-557: A central station to all parts of the United States", he was unable to overcome the inherent distance limitations of this technology. The earliest public radiotelegraph broadcasts were provided as government services, beginning with daily time signals inaugurated on January 1, 1905, by a number of U.S. Navy stations. In Europe, signals transmitted from a station located on the Eiffel Tower were received throughout much of Europe. In both

875-596: A concerted attempt to specify performance of AM receivers through the 1993 AMAX standard, a joint effort of the EIA and the NAB, with FCC backing... The FCC rapidly followed up on this with codification of the CQUAM AM stereo standard, also in 1993. At this point, the stage appeared to be set for rejuvenation of the AM band. Nevertheless, with the legacy of confusion and disappointment in the rollout of

1000-617: A consortium, the British Broadcasting Company (BBC), established on 18 October 1922, which was given a monopoly on broadcasting. This enterprise was supported by a tax on radio sets sales, plus an annual license fee on receivers, collected by the Post Office. Initially the eight stations were allowed regional autonomy. In 1927, the original broadcasting organization was replaced by a government chartered British Broadcasting Corporation . an independent nonprofit supported solely by

1125-552: A continuous-wave (CW) transmitter. Fessenden began his research on audio transmissions while doing developmental work for the United States Weather Service on Cobb Island, Maryland. Because he did not yet have a continuous-wave transmitter, initially he worked with an experimental "high-frequency spark" transmitter, taking advantage of the fact that the higher the spark rate, the closer a spark-gap transmission comes to producing continuous waves. He later reported that, in

1250-568: A few " telephone newspaper " systems, most of which were established in Europe, beginning with the Paris Théâtrophone . With this in mind, most early radiotelephone development envisioned that the device would be more profitably developed as a "wireless telephone" for personal communication, or for providing links where regular telephone lines could not be run, rather than for the uncertain finances of broadcasting. The person generally credited as

1375-463: A few hundred ( Hz ), to increase its rotational speed and so generate currents of tens-of-thousands Hz, thus producing a steady continuous-wave transmission when connected to an aerial. The next step, adopted from standard wire-telephone practice, was to insert a simple carbon microphone into the transmission line, to modulate the carrier wave signal to produce AM audio transmissions. However, it would take many years of expensive development before even

1500-748: A financial news station, and Asian Radio Live. Talk radio expanded dramatically when the BBC's monopoly on radio broadcasting was ended in the 1970s with the launch of Independent Local Radio . Some notable British talk radio presenters include Jenni Murray , John Humphrys , Martha Kearney , Jonathan Dimbleby , Libby Purves , Laurie Taylor , Pam Ayres , Melvyn Bragg , Tommy Boyd , James Whale , Steve Allen , Nick Abbot , Iain Lee , James Stannage , George Galloway , Julia Hartley-Brewer , Ian Collins , John Nicoll, Brian Hayes , Scottie McClue , James O'Brien , Nicky Campbell , and Simon Mayo . Pete Price on CityTalk

1625-530: A full schedule of talk. In the 1970s and early 1980s, as many listeners abandoned AM music formats for the high fidelity sound of FM radio , the talk radio format began to catch on in more large cities. Former music stations such as KLIF ( Dallas , Texas ), WLW ( Cincinnati, Ohio ), WHAS ( Louisville, Kentucky ), WHAM ( Rochester, New York ), WLS ( Chicago, Illinois ), KFI ( Los Angeles , California ), WRKO ( Boston , Massachusetts ), WKBW ( Buffalo, New York ), and WABC ( New York, New York ) made

1750-735: A group of stations with common ownership, although some are formed to distribute their one or two talk radio programs to several stations regardless of ownership. The largest of these is the Corus Radio Network. TSN Radio , the successor to the long-defunct the Team , is one of the newest national networks in Canada, with operations in several major markets. Syndicated programs from the United States which air on Canadian radio stations are typically non-political shows such as The Kim Komando Show and Coast to Coast AM , as well as sports radio shows from

1875-512: A home audio device prior to the introduction of the high-fidelity , long-playing record in the late 1940s. Listening habits changed in the 1960s due to the introduction of the revolutionary transistor radio (Regency TR-1, the first transistor radio released December 1954), which was made possible by the invention of the transistor in 1948. (The transistor was invented at Bell labs and released in June 1948.) Their compact size — small enough to fit in

2000-648: A less-serious lifestyle and branded content format, although still maintaining a talkback element. Melbourne , 3AW is the highest rating talkback radio station and has also been the highest rating Melbourne radio station for several decades in a row. 6PR personality Garry Meadows was the first announcer to use talkback radio in early 1967. 'Talkback' radio, using a seven-second time-lapse mechanism, began in Australia in April 1967, simultaneously on 2SM , Sydney (with Mike Walsh ) and 3DB, Melbourne (with Barry Jones ). In

2125-469: A listening site at Plymouth, Massachusetts. An American Telephone Journal account of the December 21 alternator-transmitter demonstration included the statement that "It is admirably adapted to the transmission of news, music, etc. as, owing to the fact that no wires are needed, simultaneous transmission to many subscribers can be effected as easily as to a few", echoing the words of a handout distributed to

2250-667: A longwave frequency of 385 kHz with power of 10 kW broadcasting in Russian. With the onset of World War II in 1941 and the subsequent Nazi occupation of the Ukrainian S.S.R. radio broadcast stations were captured and removed from service. At the end of World War II, during 1946, radio broadcasting began to revive and the World Radio guide of 1946 reported the following stations on the air in Ukraine: On November 1, 1950, Radio Kiev

2375-479: A majority of early broadcasting stations operated on mediumwave frequencies, whose limited range generally restricted them to local audiences. One method for overcoming this limitation, as well as a method for sharing program costs, was to create radio networks , linking stations together with telephone lines to provide a nationwide audience. In the U.S., the American Telephone and Telegraph Company (AT&T)

2500-503: A national scale. The introduction of nationwide talk shows, most prominently Rush Limbaugh 's beginning in 1988, was sometimes credited with "saving" AM radio. However, these stations tended to attract older listeners who were of lesser interest to advertisers, and AM radio's audience share continued to erode. In 1961, the FCC adopted a single standard for FM stereo transmissions, which was widely credited with enhancing FM's popularity. Developing

2625-470: A pause for advertisements; however, in public or non-commercial radio, music is sometimes played in place of commercials to separate the program segments. Variations of talk radio include conservative talk, hot talk , liberal talk (increasingly known as progressive talk), and sports talk . Talk radio has historically been associated with broadcast radio; however, starting around 2005, the technology for Internet-based talk-radio shows became cost-effective in

2750-399: A policy allowing AM stations to simulcast over FM translator stations. Translators had previously been available only to FM broadcasters, in order to increase coverage in fringe areas. Their assignment for use by AM stations was intended to approximate the station's daytime coverage, which in cases where the stations reduced power at night, often resulted in expanded nighttime coverage. Although

2875-482: A prototype alternator-transmitter would be ready, and a few years beyond that for high-power versions to become available. Fessenden worked with General Electric 's (GE) Ernst F. W. Alexanderson , who in August 1906 delivered an improved model which operated at a transmitting frequency of approximately 50 kHz, although at low power. The alternator-transmitter achieved the goal of transmitting quality audio signals, but

3000-423: A result, AM radio tends to do best in areas where FM frequencies are in short supply, or in thinly populated or mountainous areas where FM coverage is poor. Great care must be taken to avoid mutual interference between stations operating on the same frequency. In general, an AM transmission needs to be about 20 times stronger than an interfering signal to avoid a reduction in quality, in contrast to FM signals, where

3125-452: A shirt pocket — and lower power requirements, compared to vacuum tubes, meant that for the first time radio receivers were readily portable. The transistor radio became the most widely used communication device in history, with billions manufactured by the 1970s. Radio became a ubiquitous "companion medium" which people could take with them anywhere they went. The demarcation between what is considered "experimental" and "organized" broadcasting

3250-427: A short-range "wireless telephone" demonstration, that included simultaneously broadcasting speech and music to seven locations throughout Murray, Kentucky. However, this was transmitted using induction rather than radio signals, and although Stubblefield predicted that his system would be perfected so that "it will be possible to communicate with hundreds of homes at the same time", and "a single message can be sent from

3375-450: A staple of radio since the medium's infancy. Aimee Semple McPherson began her radio broadcasts in the early 1920s and even purchased her station, KFSG which went on the air in February 1924; by the mid-1930s, controversial radio priest Father Charles Coughlin 's radio broadcasts were reaching millions per week. There was also a national current events forum called America's Town Meeting of

3500-583: A talk format, for example, BBC Radio London , the BBC's flagship local station. Other notable commercial talk stations include London's LBC which pioneered the newstalk format in Europe . LBC currently operates two services – LBC , a newstalk station on FM (London) and via several digital platforms nationally including DAB and Freeview ; and LBC News , a rolling news station on AM in London and DAB+ nationally. There are many specialised talk services such as Bloomberg ,

3625-558: A talk format. Other stations such as Radio New Zealand National have a large component of talk-based content but do not have talk-back (i.e. listener phone-ins). Newstalk ZB is the New Zealand market leader, but Radio Live is continuing to try to establish itself with a greater presence in the talk radio market since its inception in 2005. Almost all AM radio stations are talk stations. A few stations from Radio Mindanao Network and Bombo Radyo are on FM. Radyo 5 News FM (now True FM)

3750-438: A way to bring his political views into listeners' homes. (He later became Mayor of Galveston ). Cherry gives no specific date, but the context of events and history of the station would seem to place it also in the 1940s, perhaps earlier. The format was the classic mode in which the announcer gave the topic for that day, and listeners called in to debate the issue. In 1948, Alan Courtney – New York disk jockey and co-composer of

3875-427: A wide variety of other devices and services including PCs using iTunes, station directories such as TuneIn, show directory smartphones with apps such as Stitcher, and time-shifting services like DAR.fm. SW Radio Africa was a pro-democracy station that broadcast out of London, England , from 2001 to 2014. In Australia , talk radio is known as "talkback radio". The most popular talkback radio station historically

4000-461: A widespread audience — dates back to the founding period of radio development, even though the earliest radio transmissions, originally known as "Hertzian radiation" and "wireless telegraphy", used spark-gap transmitters that could only transmit the dots-and-dashes of Morse code . In October 1898 a London publication, The Electrician , noted that "there are rare cases where, as Dr. [Oliver] Lodge once expressed it, it might be advantageous to 'shout'

4125-605: Is also known as the DJ who rushed to the aid of a regular caller who died live on air during a call. Previously, he had kept a teenager talking for 45 minutes before meeting him to convince him not to commit suicide. Talk radio is most popular on the AM band . "Non-commercial", usually referred to as " public radio ", which is mainly located in a reserved spectrum of the FM band , also broadcasts talk programs. Commercial all-talk stations can also be found on

4250-406: Is comparable to or better in audio quality than a standard analog broadcast". Despite the various actions, AM band audiences continued to contract, and the number of stations began to slowly decline. A 2009 FCC review reported that "The story of AM radio over the last 50 years has been a transition from being the dominant form of audio entertainment for all age groups to being almost non-existent to

4375-497: Is largely arbitrary. Listed below are some of the early AM radio broadcasts, which, due to their irregular schedules and limited purposes, can be classified as "experimental": People who weren't around in the Twenties when radio exploded can't know what it meant, this milestone for mankind. Suddenly, with radio, there was instant human communication. No longer were our homes isolated and lonely and silent. The world came into our homes for

4500-441: Is mainly dedicated to literature, the arts, classical music, and general cultural issues. Several regional stations use a format combining that of all-news and talk radio. In New Zealand , the talk radio format is popularly known as talkback radio. The major radio networks broadcasting in the talk radio format are Newstalk ZB and Radio Live . Their sports sister networks, Radio Sport and TAB Trackside also largely broadcast in

4625-426: Is music of the "Bandura". Operated multiple high power transmitters using directional phased antenna arrays. Offers distinctive QSL cards to shortwave listeners for swl dx signal reception reports. Provided clear channel reception on frequencies in the 41-meter, 31-meter, 25-meter, and 19-meter shortwave bands. Shortwave broadcasts were terminated in December 2010 from the lack of state support and funding. Since then

4750-560: Is no Canadian content requirement for talk radio, or "spoken word", programming unless the individual station's license expressly stipulates such a requirement; most do not. (In Canada, prospective radio stations may propose certain restrictions on their license to gain favor with the Canadian Radio-television and Telecommunications Commission and have an easier time obtaining a license.) The most recent nationally syndicated, politically oriented weekday talk radio show in Canada

4875-776: Is now a music station. A group of English expats set up OCI International in the early 1990s. Based in Marbella on the Costa del Sol, it was owned by the ONCE National Spanish Network. It provided a link for the English-speaking expats living on the coast, as well as some content for Scandinavian expats. OCI was closed down in 2007 to make way for Radio Europa music. In 2004 REM FM began broadcasting, with shows mostly fronted by former OCI presenters. The station closed in 2008. In 2008, Talk Radio Europe began broadcasting. It offers

5000-461: Is owned by Radio Wnet sp. z o.o., a Polish media company. Its programmes are broadcast in two large cities including Warsaw (87.8 MHz), Kraków (95,2 MHz). The programme is available via Internet. It was founded on 25 May 2009 by Krzysztof Skowroński , Grzegorz Wasowski , Katarzyna Adamiak-Sroczyńska and Monika Makowska-Wasowska , Wojciech Cejrowski and Jerzy Jachowicz . Talk radio in Spain

5125-495: Is popular. Radio 24 , part of the group Il Sole 24 Ore privately owned by Confindustria , is the most important commercial "news/talk" talk radio station in the country. Its focus is mainly on independent news about the Italian and European economy, finance, culture, and politics, but it also hosts programs focusing on sports, personal finance, music, health, science, technology, and crowdsourced storytelling. State-owned Rai Radio 3

5250-461: Is strong competition since it is also a very important time slot, when typically people going to the workplace listen to the radio in their cars early in the morning (around 7   am to 8   am). As Spain has large English-speaking communities from many different countries, it is a natural place for English language talk radio broadcasting. The first Talk radio station in English was Coastline Radio broadcasting from Nerja , Costa del Sol . It

5375-721: Is the Gascony Show . Launched in early 2011, this show is broadcast weekly to the Gascony region of the southwest of France, as well as to the rest of France via Internet streaming. Radio talk shows are popular in Germany and have a long tradition. The first talk show on public radio was Werner Höfer 's Der Internationale Frühschoppen  [ de ] , a political talk begun in 1952. The talk show on wheels Hallo Ü-Wagen ran from 1974 to 2010, begun by Carmen Thomas for WDR . Talk radio in Italy

5500-627: Is the first talk radio station in the Philippines. There is two talk radio station in Poland, called TOK FM , which is owned by Agora SA , a Polish media company. Its programmes are broadcast in 10 large cities including Warsaw , Kraków , Gdańsk , Poznań , and Katowice . The programme is also available via the Internet and transmitted by the Hot Bird constellation . It was founded in 1998 as "Inforadio" Second talk radio station called Radio Wnet , which

5625-419: Is very popular, where the most important radio stations are exclusively dedicated to talk shows, such as Cadena Ser, Cadena Cope, Onda Cero, Radio Nacional, or Punto Radio. There is a very wide variety of topics, such as politics, sport, comedy, and culture. Sport talk shows are particularly relevant, since football attracts a massive interest in Spain, with a special focus on FC Barcelona and Real Madrid CF, and

5750-556: The Electronic Industries Association (EIA) and the National Association of Broadcasters (NAB) with the intention of helping AM stations, especially ones with musical formats, become more competitive with FM broadcasters by promoting better quality receivers. However, the stereo AM and AMAX initiatives had little impact, and a 2015 review of these events concluded that Initially the consumer manufacturers made

5875-657: The Emergency Alert System (EAS). Some automakers have been eliminating AM radio from their electric vehicles (EVs) due to interference from the electric motors , but the lawmakers argue that this is a safety risk and that car owners should have access to AM radio regardless of the type of vehicle they drive. The proposed legislation would require all new vehicles to include AM radio at no additional charge, and it would also require automakers that have already eliminated AM radio to inform customers of alternatives. A proper solution would be to switch to DRM30 as indicated in

6000-479: The Federal Emergency Management Agency (FEMA) expressed concerns that this would reduce the effectiveness of emergency communications. In May 2023, a bipartisan group of lawmakers in the United States introduced legislation making it illegal for automakers to eliminate AM radio from their cars. The lawmakers argue that AM radio is an important tool for public safety due to being a component of

6125-431: The electrolytic detector and thermionic diode ( Fleming valve ) were invented by Reginald Fessenden and John Ambrose Fleming , respectively. Most important, in 1904–1906 the crystal detector , the simplest and cheapest AM detector, was developed by G. W. Pickard . Homemade crystal radios spread rapidly during the next 15 years, providing ready audiences for the first radio broadcasts. One limitation of crystals sets

6250-430: The " capture effect " means that the dominant signal needs to only be about twice as strong as the interfering one. To allow room for more stations on the mediumwave broadcast band in the United States, in June 1989 the FCC adopted a National Radio Systems Committee (NRSC) standard that limited maximum transmitted audio bandwidth to 10.2 kHz, limiting occupied bandwidth to 20.4 kHz. The former audio limitation

6375-587: The 1930s, most of the major radio stations in the country were affiliated with networks owned by two companies, NBC and CBS . In 1934, a third national network, the Mutual Radio Network , was formed as a cooperative owned by its stations. A second country which quickly adopted network programming was the United Kingdom, and its national network quickly became a prototype for a state-managed monopoly of broadcasting. A rising interest in radio broadcasting by

6500-660: The 1940s two new broadcast media, FM radio and television , began to provide extensive competition with the established broadcasting services. The AM radio industry suffered a serious loss of audience and advertising revenue, and coped by developing new strategies. Network broadcasting gave way to format broadcasting: instead of broadcasting the same programs all over the country, stations individually adopted specialized formats which appealed to different audiences, such as regional and local news, sports, "talk" programs, and programs targeted at minorities. Instead of live music, most stations began playing less expensive recorded music. In

6625-469: The 1990s and 2000s, "talkback" on FM was attempted. The Spoonman was a program hosted by Brian Carlton on the triple m network in the late 1990s and returned in 2005 for three and a half years, the show wrapping up in 2008. It was a show that covered many topics, but the "hot talk" format in the U.S. would probably be the best way to describe the program. Talkback radio has historically been an important political forum in Australia and functions much like

6750-629: The 24-hour networks in the U.S. Traditionally, politically driven talk radio from the United States does not air on Canadian stations, with a few scattered exceptions (e.g. the now-defunct CFBN , which carried political programming such as the Glenn Beck Program and Dennis Miller , and the also-discontinued talk format of CHAM , which carried Miller). Top political programs such as The Rush Limbaugh Show are never broadcast on Canadian stations, mainly due to high rights fees compared to their relevance to non-American audiences. American stations near

6875-528: The AM radio industry in the United States developed technology for broadcasting in stereo . Other nations adopted AM stereo, most commonly choosing Motorola's C-QUAM, and in 1993 the United States also made the C-QUAM system its standard, after a period allowing four different standards to compete. The selection of a single standard improved acceptance of AM stereo , however overall there was limited adoption of AM stereo worldwide, and interest declined after 1990. With

7000-460: The Air which broadcast once a week starting in 1935. It featured panel discussions from some of the biggest newsmakers and was among the first shows to allow audience participation: members of the studio audience could question the guests or even heckle them. Talk radio as a listener-participation format has existed since the 1930s. John J. Anthony (1902–1970) was an announcer and DJ on New York's WMRJ. It

7125-521: The British public pressured the government to reintroduce the service, following its suspension in 1920. However, the government also wanted to avoid what it termed the "chaotic" U.S. experience of allowing large numbers of stations to operate with few restrictions. There were also concerns about broadcasting becoming dominated by the Marconi company. Arrangements were made for six large radio manufacturers to form

7250-534: The Canadian border can provide many Canadians with access to American talk programs (the signals of Limbaugh affiliates WJR , WBEN , and WHAM , for example, cover almost all of Southern Ontario ). Local talk radio plays a significant role in the politics of Newfoundland and Labrador. Political parties have systematically coordinated call-ins by Members of the House of Assembly when public opinion pollsters are known to be in

7375-610: The FM band in many cities across the US. These shows often rely less on political discussion and analysis than their AM counterparts and often employ the use of pranks and "bits" for entertainment purposes. In the United States and Canada , satellite radio services offer uncensored "free-wheeling" original programming. ABC News & Talk is an example of "repackaging" for the digital airwaves shows featured on their terrestrial radio stations. Expressing and debating political opinions has been

7500-411: The Twenties when radio exploded can't know what it meant, this milestone for mankind. Suddenly, with radio, there was instant human communication. No longer were our homes isolated and lonely and silent. The world came into our homes for the first time. Music came pouring in. Laughter came in. News came in. The world shrank, with radio. The idea of broadcasting — the unrestricted transmission of signals to

7750-502: The United States. In an odd turn of events, Pyne's radio show led him to television. Henry suggested to John Kluge that Joe Pyne should be put on Metromedia's newly acquired TV station in Los Angeles, KTTV-TV. Kluge told Henry to speak to KTTV-TV general manager Al Kriven, but Henry had already done that, and Kriven had adamantly refused. Kluge telephoned Kriven, and Pyne soon became the nation's first controversial late-night talk television host. The Joe Pyne Show on KTTV-TV quickly shot to

7875-523: The antenna wire. This meant that the full transmitter power flowed through the microphone, and even using water cooling, the power handling ability of the microphones severely limited the power of the transmissions. Ultimately only a small number of large and powerful Alexanderson alternators would be developed. However, they would be almost exclusively used for long-range radiotelegraph communication, and occasionally for radiotelephone experimentation, but were never used for general broadcasting. Almost all of

8000-474: The audience has continued to decline. In 1987, the elimination of the Fairness Doctrine requirement meant that talk shows, which were commonly carried by AM stations, could adopt a more focused presentation on controversial topics, without the distraction of having to provide airtime for any contrasting opinions. In addition, satellite distribution made it possible for programs to be economically carried on

8125-526: The cable news televisions in the United States, with live and "saturated" coverage of political issues. The most important talk radios in Brazil are CBN , Band News and Jovem Pan , which has also sports and news broadcasts. In contrast to talk radio stations in the United States, where syndicated programs tend to make up a significant part of most schedules, privately owned Canadian talk radio stations tend to be predominantly local in programming and focus. There

8250-404: The characteristics of arc-transmitters . Fessenden attempted to sell this form of radiotelephone for point-to-point communication, but was unsuccessful. Fessenden's work with high-frequency spark transmissions was only a temporary measure. His ultimate plan for creating an audio-capable transmitter was to redesign an electrical alternator , which normally produced alternating current of at most

8375-403: The commission estimated that fewer than 250 AM stations were transmitting hybrid mode signals. On October 27, 2020, the FCC voted to allow AM stations to eliminate their analog transmissions and convert to all-digital operation, with the requirement that stations making the change had to continue to make programming available over "at least one free over-the-air digital programming stream that

8500-475: The continued migration of AM stations away from music to news, sports, and talk formats, receiver manufacturers saw little reason to adopt the more expensive stereo tuners, and thus radio stations have little incentive to upgrade to stereo transmission. In countries where the use of directional antennas is common, such as the United States, transmitter sites consisting of multiple towers often occupy large tracts of land that have significantly increased in value over

8625-437: The continuous wave AM transmissions made prior to 1915 were made by versions of the arc converter transmitter, which had been initially developed by Valdemar Poulsen in 1903. Arc transmitters worked by producing a pulsating electrical arc in an enclosed hydrogen atmosphere. They were much more compact than alternator transmitters, and could operate on somewhat higher transmitting frequencies. However, they suffered from some of

8750-434: The decades, to the point that the value of land exceeds that of the station itself. This sometimes results in the sale of the transmitter site, with the station relocating to a more distant shared site using significantly less power, or completely shutting down operations. The ongoing development of alternative transmission systems, including Digital Audio Broadcasting (DAB), satellite radio, and HD (digital) radio, continued

8875-567: The decline of the popularity of the traditional broadcast technologies. These new options, including the introduction of Internet streaming, particularly resulted in the reduction of shortwave transmissions, as international broadcasters found ways to reach their audiences more easily. In 2022 it was reported that AM radio was being removed from a number of electric vehicle (EV) models, including from cars manufactured by Tesla, Audi, Porsche, BMW and Volvo, reportedly due to automakers concerns that an EV's higher electromagnetic interference can disrupt

9000-569: The demonstration witnesses, which stated "[Radio] Telephony is admirably adapted for transmitting news, stock quotations, music, race reports, etc. simultaneously over a city, on account of the fact that no wires are needed and a single apparatus can distribute to ten thousand subscribers as easily as to a few. It is proposed to erect stations for this purpose in the large cities here and abroad." However, other than two holiday transmissions reportedly made shortly after these demonstrations, Fessenden does not appear to have conducted any radio broadcasts for

9125-687: The diagram above. AM radio technology is simpler than later transmission systems. An AM receiver detects amplitude variations in the radio waves at a particular frequency, then amplifies changes in the signal voltage to operate a loudspeaker or earphone . However, the simplicity of AM transmission also makes it vulnerable to "static" ( radio noise , radio frequency interference ) created by both natural atmospheric electrical activity such as lightning, and electrical and electronic equipment, including fluorescent lights, motors and vehicle ignition systems. In large urban centers, AM radio signals can be severely disrupted by metal structures and tall buildings. As

9250-577: The dominant method of broadcasting for the next 30 years, a period called the " Golden Age of Radio ", until television broadcasting became widespread in the 1950s and received much of the programming previously carried by radio. Later, AM radio's audiences declined greatly due to competition from FM ( frequency modulation ) radio, Digital Audio Broadcasting (DAB), satellite radio , HD (digital) radio , Internet radio , music streaming services , and podcasting . Compared to FM or digital transmissions , AM transmissions are more expensive to transmit due to

9375-600: The expectation is that listeners will primarily be tuning into the FM signal rather than the nominally "primary" AM station. A 2020 review noted that "for many owners, keeping their AM stations on the air now is pretty much just about retaining their FM translator footprint rather than keeping the AM on the air on its own merits". In 2018 the FCC, led by then-Commission Chairman Ajit Pai , proposed greatly reducing signal protection for 50 kW Class A " clear channel " stations. This would allow co-channel secondary stations to operate with higher powers, especially at night. However,

9500-445: The fall of 1900, he successfully transmitted speech over a distance of about 1.6 kilometers (one mile), which appears to have been the first successful audio transmission using radio signals. However, at this time the sound was far too distorted to be commercially practical. For a time he continued working with more sophisticated high-frequency spark transmitters, including versions that used compressed air, which began to take on some of

9625-615: The field. The provincial government routinely purchases transcripts of calls. A state-owned public channel called YLE Puhe. is broadcast throughout the whole country in the Finnish language. The programs include sports and news broadcasts. Its weekly listenership is about 550,000. Finland's first commercial talk station, Radio Rapu, started operations on March 1, 2014. Talk radio is a popular form of radio entertainment in France, exemplified by Europe 1, RTL, and RMC, plus state-owned France Inter. A premier English language talk radio in France

9750-401: The first time. Music came pouring in. Laughter came in. News came in. The world shrank, with radio. Following World War I, the number of stations providing a regular broadcasting service greatly increased, primarily due to advances in vacuum-tube technology. In response to ongoing activities, government regulators eventually codified standards for which stations could make broadcasts intended for

9875-415: The first to explore the medium in the 1950s. A breakthrough in talk radio occurred in 1960 at KLAC in Los Angeles. Alan Henry, a broadcaster in his early thirties, had been hired by John Kluge, president of Metromedia in 1963. Henry had previously worked in such diverse markets as Miami, Florida; Waterloo, Iowa; Hartford, Connecticut; and St. Louis, Missouri. KLAC was dead last in the ratings but Kluge wanted

10000-523: The first to have done so. KABC station manager Ben Hoberman and KMOX station manager Robert Hyland independently developed the all-talk format. KTKK , 630 AM in Salt Lake City, then known as KSXX, adopted a full-time talk schedule in 1965 and is the third station in the country to have done so. KSXX started with all local talent, and KTKK, which now airs on 1640 AM, has a larger portion of its schedule featuring local talent than most other stations that run

10125-413: The form of live internet website streaming and podcasts . Now, an individual can use a variety of services to host an Internet-based talk-radio show without carriage by a traditional radio station. Also, TV programming from talk and news outlets such as BBC , CNN , Bloomberg , and Fox is now often available expanding the world of talk radio further. Talk radio listening is enjoyed not only on radios but

10250-572: The general public, for example, in the United States formal recognition of a "broadcasting service" came with the establishment of regulations effective December 1, 1921, and Canadian authorities created a separate category of "radio-telephone broadcasting stations" in April 1922. However, there were numerous cases of entertainment broadcasts being presented on a regular schedule before their formal recognition by government regulators. Some early examples include: Because most longwave radio frequencies were used for international radiotelegraph communication,

10375-417: The general public, or to have even given additional thought about the potential of a regular broadcast service, and in a 1908 article providing a comprehensive review of the potential uses for his radiotelephone invention, he made no references to broadcasting. Because there was no way to amplify electrical currents at this time, modulation was usually accomplished by a carbon microphone inserted directly in

10500-438: The hosts, interviews with guests, and/or listener participation which may be live conversations between the host and listeners who "call in" (usually via telephone ) or via voice mail . Listener contributions are usually screened by a show's producers to maximize audience interest and, in the case of commercial talk radio, to attract advertisers. Talk shows on commercial stations are organized into segments, each separated by

10625-541: The isolation of rural life. Political officials could now speak directly to millions of citizens. One of the first to take advantage of this was American president Franklin Roosevelt , who became famous for his fireside chats during the Great Depression . However, broadcasting also provided the means to use propaganda as a powerful government tool, and contributed to the rise of fascist and communist ideologies. In

10750-411: The lack of any way to amplify the signals meant they were somewhat weak. On December 21, 1906, Fessenden made an extensive demonstration of the new alternator-transmitter at Brant Rock, Massachusetts, showing its utility for point-to-point wireless telephony, including interconnecting his stations to the wire telephone network. As part of the demonstration, speech was transmitted 18 kilometers (11 miles) to

10875-419: The late 1960s and 1970s, top 40 rock and roll stations in the U.S. and Canada such as WABC and CHUM transmitted highly processed and extended audio to 11 kHz, successfully attracting huge audiences. For young people, listening to AM broadcasts and participating in their music surveys and contests was the social media of the time. In the late 1970s, spurred by the exodus of musical programming to FM stations,

11000-399: The marketplace decide" which was best. The lack of a common standard resulted in consumer confusion and increased the complexity and cost of producing AM stereo receivers. In 1993, the FCC again revised its policy, by selecting C-QUAM as the sole AM stereo implementation. In 1993, the FCC also endorsed, although it did not make mandatory, AMAX broadcasting standards that were developed by

11125-505: The men's national football team. Typically the programming of main talk radio stations is modified whenever there is a major football event, such as a La Liga or a national team match. Daily late-night sport (football) talk shows are also very relevant, with a very intense competition of the radio stations in this time slot which typically starts around midnight. Comedy morning talk shows are also very popular in music radio stations (40 principales, M80 radio, Europa FM, and others), where there

11250-432: The message, spreading it broadcast to receivers in all directions". However, it was recognized that this would involve significant financial issues, as that same year The Electrician also commented "did not Prof. Lodge forget that no one wants to pay for shouting to the world on a system by which it would be impossible to prevent non-subscribers from benefiting gratuitously?" On January 1, 1902, Nathan Stubblefield gave

11375-448: The multiple incompatible AM stereo systems, and failure of the manufacturers (including the auto makers) to effectively promote AMAX radios, coupled with the ever-increasing background of noise in the band, the general public soon lost interest and moved on to other media. On June 8, 1988, an International Telecommunication Union (ITU)-sponsored conference held at Rio de Janeiro, Brazil adopted provisions, effective July 1, 1990, to extend

11500-537: The necessity of having to transmit a high power carrier wave to overcome ground losses, and the large antenna radiators required at the low broadcast frequencies, but can be sent over long distances via the ionosphere at night; however, they are much more susceptible to interference, and often have lower audio fidelity. Thus, AM broadcasters tend to specialize in spoken-word formats, such as talk radio , all-news radio and sports radio , with music formats primarily for FM and digital stations. People who weren't around in

11625-405: The new frequencies. It was now estimated that the expanded band could accommodate around 300 U.S. stations. However, it turned out that the number of possible station reassignments was much lower, with a 2006 accounting reporting that, out of 4,758 licensed U.S. AM stations, only 56 were now operating on the expanded band. Moreover, despite an initial requirement that by the end of five years either

11750-428: The new policy, by 2011 there were approximately 500 in operation, and as of 2020 approximately 2,800 of the 4,570 licensed AM stations were rebroadcasting on one or more FM translators. In 2009 the FCC stated that "We do not intend to allow these cross-service translators to be used as surrogates for FM stations". However, based on station slogans, especially in the case of recently adopted musical formats, in most cases

11875-411: The original station or its expanded band counterpart had to cease broadcasting, as of 2015 there were 25 cases where the original standard band station was still on the air, despite also operating as an expanded band station. HD Radio is a digital audio broadcasting method developed by iBiquity . In 2002 its "hybrid mode", which simultaneously transmits a standard analog signal as well as a digital one,

12000-433: The overheating issues of needing to insert microphones directly in the transmission antenna circuit. Vacuum tube transmitters also provided high-quality AM signals, and could operate on higher transmitting frequencies than alternator and arc transmitters. Non-governmental radio transmissions were prohibited in many countries during World War I, but AM radiotelephony technology advanced greatly due to wartime research, and after

12125-520: The popular song "Joltin' Joe DiMaggio" – began a call-in program for the Storer station in Miami, Florida (WGBS) and then on Miami's WQAM, WINZ and WCKR. The "Alan Courtney Open Phone Forum" flourished as an avowedly conservative and anti-communist political forum with a coverage area over the Southeastern U.S. and Cuba. Joe Pyne , John Nebel , Jean Shepherd , and Jerry Williams ( WMEX -Boston) were among

12250-474: The precision directing of radio broadcasts to desired regions worldwide. In 1966 German language programming was introduced, followed by Romanian language broadcasts in 1970, along with additional transmitting sites. By the late 1970s the following transmitting sites were active full-time on various time and frequency schedules within the territory: AM broadcasting AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It

12375-441: The primary early developer of AM technology is Canadian-born inventor Reginald Fessenden . The original spark-gap radio transmitters were impractical for transmitting audio, since they produced discontinuous pulses known as " damped waves ". Fessenden realized that what was needed was a new type of radio transmitter that produced steady "undamped" (better known as " continuous wave ") signals, which could then be "modulated" to reflect

12500-723: The radio station is now taking the first steps in multimedia development with a new website on the World Wide Web with information in text, sound and images from and about Ukraine and Ukrainians. In the 1920s and 1930s, due to the lack of accurate or reliable information, Radio Kiev or the Kiev Radio was a common name used outside of Ukraine for shortwave broadcast stations located within the Ukrainian Soviet Socialist Republic. The Wireless World guide of 1935 reported station RW20 operating from Kharkov in eastern Ukraine on

12625-592: The reception of AM transmissions and hurt the listening experience, among other reasons. However the United States Congress has introduced a bill to require all vehicles sold in the US to have an AM receiver to receive emergency broadcasts. The FM broadcast band was established in 1941 in the United States, and at the time some suggested that the AM band would soon be eliminated. In 1948 wide-band FM's inventor, Edwin H. Armstrong , predicted that "The broadcasters will set up FM stations which will parallel, carry

12750-799: The same deficiencies. The lack of any means to amplify electrical currents meant that, like the alternator transmitters, modulation was usually accomplished by a microphone inserted directly in the antenna wire, which again resulted in overheating issues, even with the use of water-cooled microphones. Thus, transmitter powers tended to be limited. The arc was also somewhat unstable, which reduced audio quality. Experimenters who used arc transmitters for their radiotelephone research included Ernst Ruhmer , Quirino Majorana , Charles "Doc" Herrold , and Lee de Forest . Advances in vacuum tube technology (called "valves" in British usage), especially after around 1915, revolutionized radio technology. Vacuum tube devices could be used to amplify electrical currents, which overcame

12875-400: The same program, as over their AM stations... eventually the day will come, of course, when we will no longer have to build receivers capable of receiving both types of transmission, and then the AM transmitters will disappear." However, FM stations actually struggled for many decades, and it was not until 1978 that FM listenership surpassed that of AM stations. Since then the AM band's share of

13000-410: The sounds being transmitted. Fessenden's basic approach was disclosed in U.S. Patent 706,737, which he applied for on May 29, 1901, and was issued the next year. It called for the use of a high-speed alternator (referred to as "an alternating-current dynamo") that generated "pure sine waves" and produced "a continuous train of radiant waves of substantially uniform strength", or, in modern terminology,

13125-440: The switch to all-talk as their ratings slumped due to listener migration to the FM band. Since the turn of the 21st century, with many music listeners now migrating to digital platforms such as Pandora Radio , Sirius XM Radio , and the numerous variations of the iPod , talk radio has been expanding on the FM side of the dial as well. Hot talk , also called FM talk or shock talk , is a talk radio format geared predominantly to

13250-411: The technology for AM broadcasting in stereo was challenging due to the need to limit the transmissions to a 20 kHz bandwidth, while also making the transmissions backward compatible with existing non-stereo receivers. In 1990, the FCC authorized an AM stereo standard developed by Magnavox, but two years later revised its decision to instead approve four competing implementations, saying it would "let

13375-647: The top of the ratings. The format later proliferated on cable television with a variety of new hosts, many of them taking on a similar persona to Joe Pyne. Joe Pyne and Alan Henry were major factors in establishing a new trend in radio and television programming. Alan Henry elaborates on the launching of Joe Pyne on KLAC radio and KTTV-TV in his memoir A Man and His Medium . Two radio stations – KMOX , 1120 AM in St. Louis, Missouri , and KABC , 790 AM in Los Angeles – adopted an all- talk show format in 1960, and both claim to be

13500-401: The translator stations are not permitted to originate programming when the "primary" AM station is broadcasting, they are permitted to do so during nighttime hours for AM stations licensed for daytime-only operation. Prior to the adoption of the new policy, as of March 18, 2009, the FCC had issued 215 Special Temporary Authority grants for FM translators relaying AM stations. After creation of

13625-492: The upper end of the Region 2 AM broadcast band, by adding ten frequencies which spanned from 1610 kHz to 1700 kHz. At this time it was suggested that as many as 500 U.S. stations could be assigned to the new frequencies. On April 12, 1990, the FCC voted to begin the process of populating the expanded band, with the main priority being the reduction of interference on the existing AM band, by transferring selected stations to

13750-548: The war the availability of tubes sparked a great increase in the number of amateur radio stations experimenting with AM transmission of news or music. Vacuum tubes remained the central technology of radio for 40 years, until transistors began to dominate in the late 1950s, and are still used in the highest power broadcast transmitters. Unlike telegraph and telephone systems, which used completely different types of equipment, most radio receivers were equally suitable for both radiotelegraph and radiotelephone reception. In 1903 and 1904

13875-404: The youngest demographic groups. Among persons aged 12–24, AM accounts for only 4% of listening, while FM accounts for 96%. Among persons aged 25–34, AM accounts for only 9% of listening, while FM accounts for 91%. The median age of listeners to the AM band is 57 years old, a full generation older than the median age of FM listeners." In 2009, the FCC made a major regulatory change, when it adopted

14000-678: Was Charles Adler Tonight , hosted by Charles Adler and heard on eleven stations across the country. After 5 years, the show ended in August 2021. Until 2006, Peter Warren's Warren on the Weekend was heard Saturdays and Sundays. Both programs are or were distributed by the Corus Radio Network and, coincidentally, both hosts had hosted different morning call-in programs in the same time slot on Winnipeg , Manitoba 's CJOB 680 before they became nationally syndicated (Adler's show originated from CJOB and retained its original title, while Warren

14125-430: Was Sydney's 2UE , whose populist programs like The John Laws Morning Show , were widely syndicated across the continent. In recent years though, 2UE has been eclipsed by its Sydney rival 2GB after the defection of 2UE most popular talkback host, Alan Jones . As a result, 2UE and owned by the same company as 2GB) abandoned most of its rigid political and hot topic -driven talkback programming in 2016, moving to

14250-549: Was 15 kHz resulting in bandwidth of 30 kHz. Another common limitation on AM fidelity is the result of receiver design, although some efforts have been made to improve this, notably through the AMAX standards adopted in the United States. Talk radio Talk radio is a radio format containing discussion about topical issues and consisting entirely or almost entirely of original spoken word content rather than outside music. They may feature monologues , dialogues between

14375-456: Was an immediate success. Henry encouraged the confrontation with listeners and guests for which Pyne became famous. Pyne coined the line "Go gargle with razor blades," for guests with whom he disagreed. The Pyne show was the beginning of the confrontational talk format that later spread across the radio spectrum. At one point in the 1960s, the Joe Pyne show was syndicated on over 250 radio stations in

14500-474: Was approved by the FCC for use by AM stations, initially only during daytime hours, due to concerns that during the night its wider bandwidth would cause unacceptable interference to stations on adjacent frequencies. In 2007 nighttime operation was also authorized. The number of hybrid mode AM stations is not exactly known, because the FCC does not keep track of the stations employing the system, and some authorized stations have later turned it off. But as of 2020

14625-611: Was based in Victoria, British Columbia .) before Charles Adler Tonight , Corus had syndicated Rutherford , hosted by conservative Dave Rutherford and originating from its Calgary station, CHQR . Rutherford is no longer syndicated nationally but continues to air in Calgary, Edmonton , and London . Other Canadian talk radio programs which have been syndicated to different markets include: Privately owned talk radio syndication networks in Canada are generally formed to share programs across

14750-475: Was bored with playing music and put a telephone receiver up to his microphone to talk with bandleader Woody Herman . This was soon followed by listener call-ins and Gray is often billed as "the hot mama of talk radio". Herb Jepko was another pioneer. Author Bill Cherry proposed George Roy Clough as the first to invite listeners to argue politics on a call-in radio show at KLUF, his station in Galveston, Texas, as

14875-459: Was fired by KABC in Los Angeles. The speculation was that Pyne was too controversial and confrontational for the ABC corporate culture. Henry hired Pyne on the spot and paid him $ 25,000 a year, which was then a huge salary for a radio personality. Pyne was given the night show on KLAC. Part of the agreement with Pyne was that Henry and Lightfoot would give him broad control of his program content. The show

15000-649: Was formally introduced and transmitted its first broadcasts in the Ukrainian language only. These broadcasts were intended to reach the Ukrainian diaspora via shortwave radio, with frequencies in the 31-, 25-, and 19-meter shortwave bands using high power amplitude modulated (AM) transmitters with omni-directional antennas. In October 1962 Radio Kiev introduced its first English language program broadcast schedule with daily transmissions on various shortwave frequencies. These transmissions originated from multiple transmitting sites employing high power Russian made (KOM) transmitters and gain type "steerable" antenna systems capable of

15125-400: Was immediately recognized that, much like the telegraph had preceded the invention of the telephone, the ability to make audio radio transmissions would be a significant technical advance. Despite this knowledge, it still took two decades to perfect the technology needed to make quality audio transmissions. In addition, the telephone had rarely been used for distributing entertainment, outside of

15250-512: Was located in the Merrick Radio Store at 12 New York Boulevard in Jamaica, Long Island. After some marital troubles, refusing to pay alimony and child support, he sought professional help and began his radio series where listeners would call in with their problems in 1930. Radio historians consider this the first instance of talk radio. While working for New York's WMCA in 1945, Barry Gray

15375-455: Was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands. The earliest experimental AM transmissions began in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained

15500-468: Was the first organization to create a radio network, and also to promote commercial advertising, which it called "toll" broadcasting. Its flagship station, WEAF (now WFAN) in New York City, sold blocks of airtime to commercial sponsors that developed entertainment shows containing commercial messages . AT&T held a monopoly on quality telephone lines, and by 1924 had linked 12 stations in Eastern cities into

15625-406: Was the lack of amplifying the signals, so listeners had to use earphones , and it required the development of vacuum-tube receivers before loudspeakers could be used. The dynamic cone loudspeaker , invented in 1924, greatly improved audio frequency response over the previous horn speakers, allowing music to be reproduced with good fidelity. AM radio offered the highest sound quality available in
