145-503: WTAR (850 AM ) is a commercial radio station licensed to Norfolk, Virginia , and serving the Hampton Roads (Norfolk- Virginia Beach - Newport News ) radio market . WTAR is owned and operated by Sinclair Telecable, Inc. It broadcasts an talk radio format as "TalkRadio 96.5 & 850 WTAR". WTAR's studios and offices are on Waterside Drive in Norfolk. The station's transmitter site

290-465: 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

435-841: 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

580-410: A black-oriented format. On this new frequency, WRAP programming could broadcast around the clock. The daytime power was increased to 5,000 watts and the nighttime power to 1,000 watts. WRAP was programmed to Norfolk's African-American community. Its call sign used the word "RAP", an African-American English word for "talk" or "discussion." (It would be several decades before " rap " began referring to

725-557: 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

870-596: 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

1015-617: 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

1160-552: 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

1305-568: 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

1450-463: 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

1595-407: A great deal of R&B (without any form of rapping), gospel music , classic soul and dance music (including disco ). Another format, rhythmic AC , in addition to playing all the popular hot and soft AC music, past and present, places a heavy emphasis on disco as well as 1980s and 1990s dance hits, such as those by Amber , and Black Box , and includes dance remixes of pop songs, such as

1740-512: 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

1885-469: 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

2030-596: A loop of Justin Timberlake 's " SexyBack " (as well as construction sound effects). (However, on September 3, WTAR broke from the stunt to air a University of Virginia football game against Richmond; the 96.5 translators remained on the stunt during that time.) On September 6, WTAR and its translators flipped to hot adult contemporary , branded as "96.5 Lucy FM", modeled after its sister station in Austin, Texas . The 850 AM signal continues to break away from "Lucy FM" programming for

2175-511: A major blow to the AC genre, and there are concerns that the portable people meter , a device being used to determine radio listenership, may be incompatible with AC songs and may not accurately pick up that a person is listening to an AC station because of the pitches and frequencies used in the style. Key AC artists of the early to mid-2010s included Bruno Mars , Coldplay , Adele , Arcade Fire , Meghan Trainor , Maroon 5 and Ed Sheeran , featuring

2320-479: 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)

2465-476: A more conservative music library than hot AC-leaning stations. In particular, Chicago's WLIT did not have its airstaff talk over the beginning and endings of songs (in contrast to the hot AC-leaning WFYR ), and played Bob Seger 's " We've Got Tonite " but not " Old Time Rock and Roll " (which was part of WTMX 's playlist). The director of a soft AC station in Connecticut, WEZN-FM , told Warren that he had barred

2610-716: A more pop-influenced, uptempo style than the typical AC fare of previous years, also featuring production values reminiscent of the Motown sound and the so-called Wall of Sound that dominated the soul-heavy pop charts of the early 1960s, when the Easy Listening chart was first introduced. The earlier years of the decade also saw alternative and indie rock acts such as Wilco , Feist , The 1975 , Imagine Dragons , Mumford & Sons , Of Monsters and Men and The Lumineers quickly becoming AC mainstays, although these were eventually replaced by rhythm-based rock bands such as Panic! at

2755-472: A more uptempo direction. In 2017, Inside Radio reported that soft AC had the third-largest decrease in US stations offering the format over the past decade (at 128), ranking behind only adult standards and oldies —a shift credited to aging demographics and a major boom in the wider-appealing classic hits format (which saw the largest overall increase over the same period). Consultant Gary Berkowitz argued that

2900-408: A musical style.) An advertisement in the 1957 edition of Broadcasting Yearbook , using the descriptions of the era, said "Survey figures show the most Negroes in the Norfolk area listen most to WRAP." It added that WRAP was "the only all-Negro station in Norfolk." In 1987, WNIS on AM 1350 was acquired by local cable TV company Clinton Cablevision (later Sinclair Telecable). The new owner flipped

3045-503: 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

3190-399: 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

3335-482: 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

3480-408: A radio station that everybody goes, 'I'm okay with that'." The increasingly downtempo direction of pop hits in the mid-to-late 2010's also helped to attract additional listeners. Hot AC stations typically keep a larger body of recent hits in rotation than those with rigid, chart-driven formats like CHR and urban contemporary . As these stations' playlists have become concentrated towards airing only

3625-423: 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

3770-452: 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

3915-427: 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

4060-521: A similar "lite" format by choosing certain tracks (both hit singles and album cuts) of popular artists. By the late 1960s hard rock had been established as one of the rock genres leading hard rock and soft rock to became distinct popular forms in the rock scene, and as major radio formats in the US. Soft rock was often derived from folk rock, using acoustic instruments and putting more emphasis on melody and harmonies. Major artists included Carole King , Cat Stevens , James Taylor and Bread . In

4205-421: A similar playlist to hot AC stations, but with a broader rotation of classic hits from past decades. Soft adult contemporary formats have a more conservative sound oriented primarily towards adult women, urban AC focuses on R&B and soul music that appeal to African American adults, and rhythmic AC focuses on dance music and other rhythmic genres. Hot adult contemporary (hot AC) radio stations play

4350-617: A stronger lean towards modern rock and pop rock . In the 1990s and early 2000s, modern AC was typically targeted towards women, with Mike Marino of KMXB in Las Vegas describing the format as reaching "an audience that has outgrown the edgier hip-hop or alternative music but hasn't gotten old and sappy enough for the soft ACs." The format typically focused on female rock acts such as Shawn Colvin , Sheryl Crow , Indigo Girls , Jewel , and Sarah McLachlan , and folk rock -influenced bands such as Counting Crows and The Wallflowers . Today,

4495-643: A wide range of popular music that appeals towards the 18–54 age group; it serves as a middle ground between the youth-oriented contemporary hit radio (CHR) format, and adult contemporary formats (such as "mainstream" and soft AC) that are typically targeted towards a more mature demographic. They generally feature uptempo hit music from the last 25 years with wide appeal, such as pop and pop rock songs, while excluding more youth-oriented music such as hip-hop . Older music featured on hot AC stations usually reflects familiar and youthful music that adults had grown up with. Likewise, material from legacy pop acts such as

4640-461: 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'

4785-470: A year after its original release, became a sleeper hit on the Billboard Mainstream Top 40 and Hot 100 due in part to strong hot AC airplay). The popularity of the hot AC format prompted many mainstream AC stations to add uptempo music to their playlists, while still maintaining a deeper rotation of older hits than hot AC stations. Modern adult contemporary refers to AC formats with

4930-449: Is also heard on HD Radio over 106.1 WUSH-HD2 and on FM translator station W243DJ at 96.5 MHz in Norfolk and W243EK at 96.5 MHz in Hampton. The station, originally WCAV, began broadcasting in 1952, transmitting on 860 kHz. In 1954, owners of another Norfolk radio station, WRAP on 1050 kHz, acquired WCAV, moving it to 850 kHz and changing its call letters to WRAP and adopting

5075-519: Is another subgenre of radio programming that is distinct from the Hot Adult Contemporary Tracks chart as it exists today, despite the apparent similarity in name. In response to the pressure on Hot AC, a new kind of AC format cropped up among American radio recently. The urban adult contemporary format (a term coined by Barry Mayo ) usually attracts a large number of African Americans and sometimes Caucasian listeners through playing

5220-406: 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

5365-433: Is generally a continuation of the easy listening and soft rock style that became popular in the 1960s and 1970s with some adjustments that reflect the evolution of pop/rock music. Adult contemporary tends to have lush, soothing and highly polished qualities where emphasis on melody and harmonies is accentuated. It is usually melodic enough to get a listener's attention, abstains from profanity or complex lyricism, and

5510-497: 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

5655-494: Is most commonly used as background music in heavily-frequented family areas such as supermarkets , shopping malls , convention centers , or restaurants . Like most of pop music , its songs tend to be written in a basic format employing a verse–chorus structure . The format is heavy on romantic sentimental ballads which use acoustic instruments such as pianos , saxophones , and sometimes an orchestral set. However, electric guitars and bass are also usually used, with

5800-623: Is off Track Lane in Smithfield, Virginia . WTAR uses a directional antenna at all times. It runs at 50,000 watts by day, the highest power permitted by the Federal Communications Commission for AM stations. At night, to reduce interference to other stations on 850 AM , mainly Class A KOA in Denver , WTAR reduces power to 25,000 watts, concentrating the signal in Norfolk, Virginia Beach , Hampton and Newport News . WTAR programming

5945-645: 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

6090-520: The Backstreet Boys , Jason Mraz , John Mayer , and Pink is prominent within the format. The "hot AC" designation began to appear in the 1990s; the term described adult contemporary stations with a more energetic presentation and uptempo sound than their softer counterparts. An early example of the format, Houston's KHMX Mix 96.5 , climbed from 14th place in the market to third in the six months after its launch. The station's format and branding

6235-519: The Carpenters , Dionne Warwick , Barry Manilow , John Denver , and Olivia Newton-John found it harder to have major Top 40 hits as the 1980s wore on, and due to the influence of MTV, artists who were staples of the Contemporary Hit Radio format, such as Richard Marx , Michael Jackson , Bonnie Tyler , George Michael , Phil Collins , Laura Branigan and Journey began crossing over to

6380-556: 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

6525-615: 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. AM radio technology

6670-479: 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

6815-541: The Jonas Brothers and Halsey began to be featured on AC stations more than on top 40 stations. In radio broadcasting, adult contemporary is divided into several sub-formats, each with their own musical direction and demographic targeting. Hot adult contemporary formats generally feature an uptempo rotation of recent hits that appeal to a wide adult audience. A station formatted as "adult contemporary" with no qualifier, also referred to as "mainstream" AC, generally has

6960-467: The Soul Solution mix of Toni Braxton 's "Unbreak My Heart". In its early years of existence, the smooth jazz format was considered to be a form of AC, although it was mainly instrumental, and related a stronger resemblance to the soft AC-styled music. For many years, George Benson , Kenny G and Dave Koz had all had crossover hits that were played on both smooth jazz and soft AC stations. During

7105-431: 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

7250-430: 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

7395-436: The "Coast" branding to the market for the first time since WKOC 's flip in 2003. On September 3, 2024, the station's owner, Sinclair Communications announced that it would flip WTAR and its two translators to conservative talk radio "Talkradio 96.5/850" on Monday, September 16.

7540-587: 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

7685-501: The 1940s and early 1950s. After 1965, differences between the Hot 100 chart and the Easy Listening chart became more pronounced. Better reflecting what middle of the road stations were actually playing, the composition of the chart changed dramatically. As rock music continued to harden, there was much less crossover between the Hot 100 and Easy Listening chart than there had been in the early half of

7830-660: 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

7975-590: The 1960s. Roger Miller , Barbra Streisand and Bobby Vinton were among the chart's most popular performers. One big impetus for the development of the AC radio format was that, when rock and roll music first became popular in the mid-1950s, many more conservative radio stations wanted to continue to play current hit songs while shying away from rock. These middle of the road (or "MOR") stations also frequently included older, pre-rock-era adult standards and big band titles to further appeal to adult listeners who had grown up with those songs. Another big impetus for

8120-453: The 1980s, soft rock songs still enjoyed a mild success thanks to Sheena Easton , Amy Grant , Lionel Richie , Christopher Cross , Dan Hill , Leo Sayer , Billy Ocean , Julio Iglesias , Bertie Higgins , and Tommy Page . No song spent more than six weeks at No. 1 on this chart during the 1980s, with nine songs accomplishing that feat. Two of these were by Lionel Richie, " You Are " in 1983 and " Hello " in 1984, which also reached No. 1 on

8265-675: The 1980s, the soft AC format was positioned as being a more upbeat version of easy listening that would appeal better to a younger audience, mainly by excluding instrumental beautiful music . Easy listening stations had begun shifting to the format out of concern that their existing programming would not appeal to the current generation of listeners. In a 1990 article, James Warren of the Chicago Tribune characterized soft AC stations as being "as middle-of-the-road and unthreatening as modern media get", with personalities that were encouraged to be as inoffensive and "low-profile" as possible, and

8410-499: The 1980s. The growth of AC was a natural result of the generation that first listened to the more "specialized" music of the mid-late 1970s growing older and not being interested in the heavy metal and rap/hip-hop music that a new generation helped to play a significant role in the Top 40 charts by the end of the decade. Mainstream AC itself has evolved in a similar fashion over the years; traditional AC artists such as Barbra Streisand ,

8555-671: The 1990s and early 2000s such as Britney Spears and Christina Aguilera were added to the rotation of most AC stations. As trap music and similar styles of hip-hop began dominating top 40 stations during the last years of the 2010s, AC stations began picking up rhythmic artists like Rihanna , Lady Gaga , Ellie Goulding , Taio Cruz and Pitbull as well as EDM artists like Avicii , Daft Punk , Calvin Harris , David Guetta and Tiesto . Meanwhile, younger artists like Camila Cabello , Justin Bieber , Selena Gomez , Ariana Grande , Nick Jonas and

8700-475: The 1990s, to improve their appeal among changing demographics, some soft AC stations began to widen their playlist to include selections from contemporary acts with 80s, & 90s, musicians & bands such as Bon Jovi , Bryan Adams , Celine Dion , Roxette , Mariah Carey , Eric Clapton , Phil Collins , Elton John , Cher , Whitney Houston , Journey , and Queen . On the other hand, by 1996, New York's WLTW had begun to phase out its softer music in favor of

8845-588: The 2000s, country music / countrypolitan musicians such as Kelly Clarkson , Clay Aiken , Billy Joel , Garth Brooks , Shania Twain , LeAnn Rimes and Carrie Underwood scored hits on soft AC, particularly in Southern states. A popular trend in the late 1990s and 2000s was remixing dance music hits into adult contemporary ballads, especially in the US, (for example, the "Candlelight Mix" versions of " Heaven " by DJ Sammy and Yanou , "Listen To Your Heart" by D.H.T. , and " Everytime We Touch " by Cascada ). Key to

8990-556: The 2000s, the AC market gained an increased presence in the music industry, as its radio formats were popular nationwide—Smooth jazz and "Urban AC" stations were ubiquitous in the East Coast, while Soft rock and "adult standards" stations were common in the Midwest, and pop-oriented "Hot AC" and "world music"/Hispanic AC stations were easily found in the West Coast and the "Sun Belt". This led to

9135-723: The 25–44 age group, the demographic that has received the most attention from advertisers since the 1960s. A common practice in recent years of adult contemporary stations is to play less newer music and more hits of the past, even some songs that never even charted the AC charts. This de-emphasis on new songs slows the progression of the AC chart. Over the years, AC has spawned subgenres including "hot AC" (or "modern AC"), "soft AC" (also known as "lite AC"), " urban AC " (a softer type of urban contemporary music ), " rhythmic AC " (a softer type of rhythmic contemporary ), and " Christian AC " (a softer type of contemporary Christian music ). Some stations play only "hot AC", "soft AC", or only one of

9280-536: The AC chart during this time. In 1996, Billboard created a new chart called Adult Top 40 , which reflects programming on radio stations that exists somewhere between "adult contemporary" music and "pop" music. Although they are sometimes mistaken for each other, the Adult Contemporary chart and the Adult Top 40 chart are separate charts, and songs reaching one chart might not reach the other. In addition, hot AC

9425-425: The AC charts with greater frequency. Collins has been described by AllMusic as "one of the most successful pop and adult contemporary singers of the '80s and beyond". However, with the combination of MTV and AC radio, adult contemporary appeared harder to define as a genre, with established soft-rock artists of the past still charting pop hits and receiving airplay alongside mainstream radio fare from newer artists at

9570-447: The AC charts. In addition to Celine Dion , who has had significant success on this chart, other artists with multiple number ones on the AC chart in the 1990s include Mariah Carey , Phil Collins , Michael Bolton , Bryan Adams , Whitney Houston and Shania Twain . Newer female Adult album alternative singer-songwriters such as Sarah McLachlan , Natalie Merchant , Jewel , Melissa Etheridge and Sheryl Crow also broke through on

9715-528: 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

9860-521: 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

10005-729: The Disco , Neon Trees , X Ambassadors , Sheppard , Bastille , American Authors , Fitz and the Tantrums , Foster the People , Twenty One Pilots , Walk the Moon and Milky Chance . During the middle of the decade, newer artists such as CeeLo Green , OneRepublic , Rachel Platten , Christina Perri , Andy Grammer , James Bay , Sara Bareilles , Shawn Mendes , Sia , Sam Smith , Gavin Degraw , Charlie Puth and Colbie Caillat as well as acts that were popular in

In 1989, Linda Ronstadt released Cry Like a Rainstorm, Howl Like the Wind , described by critics as "the first true Adult Contemporary album of the decade", featuring American soul singer Aaron Neville on several of the twelve tracks. The album was certified Triple Platinum in the United States alone and became a major success throughout the globe. The Grammy Award -winning singles, " Don't Know Much " and " All My Life ", were both long-running No. 1 Adult Contemporary hits. Several additional singles from

10440-428: The U.S., for example) subject to international agreements. Hot adult contemporary Adult contemporary music ( AC ) is a form of radio -played popular music , ranging from 1960s vocal and 1970s soft rock music to predominantly ballad -heavy music of the 1980s to the present day, with varying degrees of easy listening , pop , soul , R&B , quiet storm and rock influence. Adult contemporary

10585-662: The United States and France this led to a small market of receiver lines geared for jewelers who needed accurate time to set their clocks, including the Ondophone in France, and the De Forest RS-100 Jewelers Time Receiver in the United States The ability to pick up time signal broadcasts, in addition to Morse code weather reports and news summaries, also attracted the interest of amateur radio enthusiasts. It

10730-637: The University of Virginia broadcasts. Until September 1, 2022, the station aired a sports radio format , carrying the Fox Sports Radio Network most of the day, with a local afternoon drive time show. The syndicated Dan Patrick Show was heard in late mornings. WTAR was part of the Washington Commanders Radio Network. On March 20, 2023, WTAR flipped to adult album alternative, branded as "96.5 The Coast". The flip returns

10875-523: 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

11020-474: 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

11165-730: The brand (among others) being adopted by competitors such as Entercom . Industry analyst Sean Ross argued that older demographics were becoming more lucrative due to changes in listening habits among younger audiences, which prefer digital platforms such as music streaming services over linear terrestrial radio, and also noted how mainstream AC was dependent on the Top 40 charts to break new songs. Current soft AC stations have continued to feature recurrents such as Michael Bolton , Celine Dion , Elton John, Fleetwood Mac , Hall & Oates , and Whitney Houston, while contemporary musicians such as Adele and Michael Bublé have also become modern fixtures of

11310-404: 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

11455-403: 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

11600-475: 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

11745-437: 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

11890-428: The current hits at a given time, hot AC airplay can build and sustain a song's popularity over a long-term period. This effect has been credited in helping build an audience for early singles from new acts such as Adele , Rachel Platten (" Fight Song ", which gained prominence for its use during Hillary Clinton 's 2016 US presidential election campaign ), and Max Schneider (whose 2016 single " Lights Down Low ", over

12035-434: 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

12180-567: 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

12325-569: 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

12470-460: The disc made the AC Top 10 as well. The album won over many critics in the need to define AC, and appeared to change the tolerance and acceptance of AC music into mainstream day to day radio play. The early 1990s marked the softening of urban R&B in the shape of new jack swing, at the same time alternative rock emerged and traditional pop saw a significant resurgence. This in part led to a widening of

12615-511: The early 1970s, softer songs by The Carpenters , Anne Murray , John Denver , Barry Manilow , and even Barbra Streisand , began to be played more often on "Top 40" radio. Top 40 radio stations played the Top 40 hits regardless of genre. As the texture of much of the music played on Top 40 radio began to soften, the Hot 100 and Easy Listening/AC charts became more similar. Easy Listening radio began playing songs by artists who had begun in other genres, such as rock and roll or R&B . Much of

12760-446: The electric guitar sound relatively faint and high-pitched. Additionally, post-80s adult contemporary music may feature synthesizers (and other electronics, such as drum machines ). An AC radio station may play mainstream music, but it usually excludes hip hop , house/techno or electronic dance music and some forms of dance-pop and teen pop , as these are less popular among adults, the target demographic . AC radio often targets

12905-412: The evolution of the AC radio format was the popularity of easy listening or " beautiful music " stations, stations with music specifically designed to be purely ambient . Whereas most easy listening music was instrumental, created by relatively unknown artists, and rarely purchased (especially as singles, although Jackie Gleason 's beautiful music albums sold well in the 1950s), AC was an attempt to create

13050-645: 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,

13195-445: 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

13340-401: 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

13485-437: The format during the 2010s. These developments helped to expand the popularity of the format among younger listeners such as millennials ; Nielsen Audio ranked hot AC as the third most-popular format among millennials, behind pop and country music . Of the format's expanding demographic reach, WOMX-FM program director Dana Taylor stated that hot AC stations "may not be the radio station that everybody agrees on, but it's

13630-540: The format is fairly uncommon, with KTCZ in the Minnesota Twin Cities and KMXP in Phoenix, Arizona being some of the few modern AC stations left. The Soft adult contemporary format typically targets women 25–54 and at-work listening. Soft AC playlists are generally conservative in comparison to hot AC, focusing on pop and power ballads , soft rock , and other familiar, light hits. Upon its establishment in

13775-648: The format to talk. A swap was made with AM 1350, which moved the WNIS call sign to this station, and transferred the WRAP call letters, with its associated black-oriented format, to AM 1350. WNIS, meaning "News and Information Station", picked up programming from ABC Talkradio , NBC Talknet and the Mutual Broadcasting System 's Larry King Show. On July 15, 1997, WNIS and its sister station on AM 790, WTAR, exchanged call letters, with AM 790 becoming WNIS, while WTAR

13920-529: The format until the early 1970s), new age songs and most pre-1964 artists were gradually phased out from AC radio throughout the early to mid-1990s. Unlike the majority of 1980s mainstream singers, the 1990s mainstream pop/R&B singers such as All-4-One , Boyz II Men , Christina Aguilera , Backstreet Boys and Savage Garden generally crossed over to the AC charts. Latin pop artists such as Lynda Thomas , Ricky Martin , Marc Anthony , Selena , Enrique Iglesias and Luis Miguel also enjoyed success in

14065-590: The format. In addition, the soft AC sound has diversified to include more songs that are "safe and universal" but not necessarily "soft", with Ross presenting examples such as Simple Minds ' " Don't You (Forget About Me) ", the retroactively-defined genre of yacht rock , and noting that KSWD in Seattle—one of the stations that had launched in the soft AC "boom" of the late-2010s—had featured dance- and synth-pop songs such as " Poker Face ", " Sweet Dreams (Are Made of This) ", and " Uptown Funk " in its final days as

14210-620: 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,

14355-417: 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

14500-498: The hits had become established. An article on MTV 's website by Corey Moss describes this trend as: "In other words, AC stations are where pop songs go to die a very long death. Or, to optimists, to get a second life." As adult contemporary has long characterized itself as family-friendly, "clean" versions of pop songs began appearing on the AC chart, as were the cases of " Perfect " by P!nk , and " Forget You " by Cee Lo Green , both in 2011. AC radio's shift into more mainstream pop

14645-541: 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

14790-411: 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

14935-419: 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,

15080-408: The late 2000s, certain pop songs began entering the AC charts instead, generally after having recently fallen off the Hot 100. Adrian Moreira, senior vice president for adult music for RCA Music Group , said, "We've seen a fairly tidal shift in what AC will play". Rather than emphasizing older songs, adult contemporary now began playing many of the same songs as top 40 and adult top 40 , but only after

15225-407: The late-1970s. This led to specialized radio stations that played specific genres of music, and generally followed the evolution of artists in those genres. On April 7, 1979, the Easy Listening chart officially became known as Adult Contemporary, and those two words have remained consistent in the name of the chart ever since. Adult contemporary music became one of the most popular radio formats of

15370-427: The market, not only allowing to cater to more niche markets, but it also became customary for artists to make AC-friendly singles. At the same time, the genre began adopting elements from hard rock as tastes were shifting towards louder music, while AC stations in general began playing more rock acts. "Softer" features such as light instrumental music (carried over from the beautiful music format—many AC stations carried

15515-399: 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

15660-432: 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

15805-448: 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

15950-414: The music recorded by singer-songwriters such as Diana Ross , James Taylor , Carly Simon , Carole King and Janis Ian got as much, if not more, airplay on AC stations than on Top 40 stations. AC stations also began playing softer songs by Elvis Presley , Linda Ronstadt , Elton John , Rod Stewart , Billy Joel , and other rock-based artists. Soon after, the adult contemporary format began evolving into

16095-537: 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

16240-405: 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

16385-428: 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

16530-411: 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,

16675-433: 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

16820-738: The presence of numerous genres on the AC charts, often crossing to the "pop" charts, winning over many critics in the need to define AC, and increased the tolerance and acceptance of AC music into mainstream day-to-day radio play. Josh Groban 's single " You Raise Me Up " and Michael Bublé 's cover of "Fever" are often cited as key examples of the high production values and ballad-heavy sound that defined 2000s-era AC, often dubbed as "jazz-pop", heavily carrying classical, jazz and traditional pop influences. Artists such as Nick Lachey , James Blunt , Jamie Cullum , John Mayer , Jason Mraz , Norah Jones , Diana Krall , Amy Winehouse and Susan Boyle also achieved great success during this period. During most of

16965-441: 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

17110-487: The reading of top-of-hour news headlines, so that listeners wouldn't be tempted to tune away to an all-news station to learn more. Soft AC stations tend to be more selective in their music libraries than other adult contemporary stations, preferring proven songs over current hits. Upon the onset of the format's popularity, core artists typically included singers such as Nat King Cole , Perry Como , Neil Diamond , Barry Manilow , Johnny Mathis , and Barbra Streisand . By

17255-592: 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

17400-539: The reformed Fleetwood Mac , whose Rumours (1977) was the best-selling album of the decade. By 1977, some radio stations, notably New York's WTFM and NBC -owned WYNY , and Boston's WEEI , had switched to an all-soft rock format. As Softrock 103 , WEEI was famous for its promotional campaigns, featuring slogans such as " Joni , without the baloni." and " The Byrds , without the nyrds." However, different forms of popular music targeted to different demographic groups, such as disco vs. hard rock , began to emerge in

17545-799: 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

17690-400: 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

17835-549: The soft AC format had become increasingly irrelevant in comparison to mainstream and hot AC, due to PPM markets preferring uptempo music. At the same time, however, soft AC began to experience a resurgence. In April 2016, iHeartMedia flipped its San Francisco classic soul station KISQ to soft AC as The Breeze ; as of November 2018, it was the top station in the Bay Area. The trend continued into 2017 and 2018, with iHeartMedia extending its Breeze brand to other soft AC flips, and

17980-450: The sound that later defined it, with rock-oriented acts as Chicago and the Eagles , becoming associated with the format. In addition, several early disco songs, did well on the Adult Contemporary format. Soft rock reached its commercial peak in the mid-to-late 1970s with acts such as Toto , England Dan & John Ford Coley , Air Supply , Seals and Crofts , Dan Fogelberg , America and

18125-410: 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,

18270-548: The station on either AM or FM, although the FM translator signal is limited to Norfolk and surrounding communities due to its low power of 120 watts. The station also signed on another low-powered FM translator, W243EK in Hampton (on the same frequency of W243DJ), to improve its nighttime signal on the Lower Peninsula and the HRBT's AM/FM rebroadcast system. On September 1, 2022, WTAR dropped its sports format and began stunting with

18415-400: The success of AC in the 2000s was the 25–34 demographic which had outgrown the pop music offerings of the time, most new rock became too alternative and harsh for AC radio and most new pop was now influenced heavily by dance-pop , hip-hop and electronic dance music . At the same time, the music industry also began to focus on older audiences and markets generally considered "niche". During

18560-411: 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

18705-504: The time. The amount of crossover between the AC chart and the Hot 100 has varied based on how much the passing pop music trends of the times appealed to adult listeners. Not many disco or new wave songs were particularly successful on the AC chart during the late 1970s and early 1980s, and much of the hip-hop and harder rock music featured on CHR formats later in the decade would have been unacceptable on AC radio. Although dance-oriented, electronic pop and ballad-oriented rock dominated

18850-401: 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

18995-492: 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

19140-419: The variety of subgenres. Therefore, it is not usually considered a specific genre of music; it is merely an assemblage of selected songs from artists of many different genres . Adult contemporary traces its roots to the 1960s easy listening format, which adopted a 70–80% instrumental to 20–30% vocal mix. A few offered 90% instrumentals, and a handful were entirely instrumental. The easy listening format, as it

19285-421: The vocalists consisted of artists such as Frank Sinatra , Doris Day , Johnny Mathis , Connie Francis , Nat King Cole , Perry Como , and others. The custom recordings were usually instrumental versions of current or recent rock and roll or pop hit songs, a move intended to give the stations more mass appeal without selling out . Some stations would also occasionally play earlier big band -era recordings from

19430-548: 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

19575-404: 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

19720-565: 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. AM broadcasts are used on several frequency bands. The allocation of these bands is governed by the ITU 's Radio Regulations and, on the national level, by each country's telecommunications administration (the FCC in

19865-417: Was a result of the changes on the broadcasting landscape following the 2005–2007 economic downturn and eventual recession , as advertisers preferred more profitable chart-based formats, which meant the demise of many AC-based formulas, primarily those aimed at older audiences, with tastes changing towards more modern music among all age groups. Diminishing physical record sales throughout the 2010s also proved

20010-474: 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

20155-442: Was first known, was born of a desire by some radio stations in the late 1950s and early 1960s to continue playing current hit songs but distinguish themselves from being branded as " rock and roll " stations. Billboard first published the Easy Listening chart July 17, 1961, with 20 songs; the first number one was " Boll Weevil Song " by Brook Benton . The chart described itself as "not too far out in either direction". Initially,

20300-400: 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

20445-544: Was moved to 850 kHz. 850 has the stronger signal, broadcasting at 50,000 watts by day, the highest power authorized for AM stations by the Federal Communications Commission . At night it runs 25,000 watts, while 790 kHz transmits 5,000 watts day and night. Both stations had talk formats. WTAR flipped from talk radio to an all-sports format on February 5, 2006. On September 15, 2017, WTAR began simulcasting on WUSH-HD2 and FM translator station W243DJ at 96.5 MHz in Norfolk. The move allows WTAR listeners to hear

20590-703: Was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained 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.
