145-725: WOGL (98.1 FM ) is a commercial radio station licensed to serve Philadelphia, Pennsylvania . The station is owned by Audacy, Inc. and broadcasts a classic hits radio format . The broadcast tower used by the station is located in the Roxborough section of Philadelphia, at ( 40°2′30″N 75°14′10″W  /  40.04167°N 75.23611°W  / 40.04167; -75.23611 ). The station's studios and offices are co-located within Audacy's corporate headquarters in Center City Philadelphia . The station features mostly hits from

290-443: A horn section , a string orchestra , and a variety of " classical " solo instruments (for example, flute, piccolo, and so on). Disco songs were arranged and composed by experienced arrangers and orchestrators , and record producers added their creative touches to the overall sound using multitrack recording techniques and effects units . Recording complex arrangements with such a large number of instruments and sections required

435-399: A 500 kHz frequency separation even when closer frequency spacing is technically permitted. The ITU publishes Protection Ratio graphs, which give the minimum spacing between frequencies based on their relative strengths. Only broadcast stations with large enough geographic separations between their coverage areas can operate on the same or close frequencies. Frequency modulation or FM

580-443: A Dance Floor , Random Access Memories , Future Nostalgia , and Kylie Minogue 's album itself titled Disco . Modern day artists like Dua Lipa , Bruno Mars and Silk Sonic have continued the genre's popularity, bringing it to a whole new younger generation. The term "disco" is shorthand for the word discothèque , a French word for "library of phonograph records" derived from "bibliothèque". The word "discotheque" had

725-486: A beat (which in 4/4 time is 4 beats per measure). Disco is further characterized by a 16th note division of the quarter notes (as shown in the second drum pattern in the picture above, after a typical rock drum pattern). The orchestral sound usually known as "disco sound" relies heavily on string sections and horns playing linear phrases, in unison with the soaring, often reverberated vocals or playing instrumental fills, while electric pianos and chicken-scratch guitars create

870-413: A couple of weeks to a month or so. [...] And then as we move through the spring and into the summer, we will add some additional hosts for mid-day afternoon and evening." The change also resulted in the unannounced departure of the station's longtime weekend program "Bob Pantano’s Dance Party", which had been heard on the station on Saturday nights and would move to the station's HD2 subchannel after being on

1015-542: A deep playlist, playing a larger number of songs than most oldies stations. For the next year, WOGL and WIOQ competed for Philadelphia's FM oldies audience, until WIOQ dropped the format early in 1989. Scott Walker, who programmed Hot Hits WCAU-FM, remained as Program Director . Originally, WOGL was known as "Oldies 98". By 1992, WOGL incorporated more soul oldies. The station still played artists such as Elvis , The Beatles and The Rolling Stones , but in addition, it focused on soul, including Philadelphia-only hits. The mix

1160-402: A fax program. The original subcarrier frequency used at KE2XCC was 27.5 kHz. The IF bandwidth was ±5 kHz, as the only goal at the time was to relay AM radio-quality audio. This transmission system used 75 μs audio pre-emphasis like the main monaural audio and subsequently the multiplexed stereo audio. In the late 1950s, several systems to add stereo to FM radio were considered by

1305-551: A group of accompanying musicians who were among the most dextrous, knowledgeable, and brilliant in all of popular music (Motown bassists have long been the envy of white rock bassists) and 7) a trebly style of mixing that relied heavily on electronic limiting and equalizing (boosting the high range frequencies) to give the overall product a distinctive sound, particularly effective for broadcast over AM radio." Motown had many hits with disco elements by acts like Eddie Kendricks (" Keep on Truckin' " in 1973, " Boogie Down " in 1974). At

1450-441: A key influence in the development of electronic dance music , house music , hip hop , new wave , dance-punk , and post-disco . The style has had several revivals since the 1990s , and the influence of disco remains strong across American and European pop music. A revival has been underway since the early 2010s , coming to great popularity in the early 2020s . Albums that have contributed to this revival include Confessions on

1595-465: A key part of the disco club experience. The Loft party host David Mancuso introduced the technologies of tweeter arrays (clusters of small loudspeakers, which emit high-end frequencies, positioned above the floor) and bass reinforcements (additional sets of subwoofers positioned at ground level) at the start of the 1970s to boost the treble and bass at opportune moments, and by the end of the decade sound engineers such as Richard Long had multiplied

1740-697: A major trend in popular music in the United States following the infamous Disco Demolition Night on July 12, 1979, and it continued to sharply decline in popularity in the U.S. during the early 1980s ; however, it remained popular in Italy and some European countries throughout the 1980s, and during this time also started becoming trendy in places elsewhere including India and the Middle East , where aspects of disco were blended with regional folk styles such as ghazals and belly dancing . Disco would eventually become

1885-406: A merengue, are commonplace. The quaver pattern is often supported by other instruments such as the rhythm guitar and may be implied rather than explicitly present. Songs often use syncopation , which is the accenting of unexpected beats. In general, the difference between disco, or any dance song, and a rock or pop song is that in dance music the bass drum hits four to the floor , at least once

2030-428: A non-phallic full body eroticism. Through a range of percussion instruments, a willingness to play with rhythm, and the endless repeating of phrases without cutting the listener off, disco achieved this full-body eroticism by restoring eroticism to the whole body for both sexes. This allowed for the potential expression of sexualities not defined by the cock/penis, and the erotic pleasure of bodies that are not defined by

2175-557: A program feed for AM transmitters of AM/FM stations. SCA subcarriers are typically 67 kHz and 92 kHz. Initially the users of SCA services were private analog audio channels which could be used internally or leased, for example Muzak -type services. There were experiments with quadraphonic sound. If a station does not broadcast in stereo, everything from 23 kHz on up can be used for other services. The guard band around 19 kHz (±4 kHz) must still be maintained, so as not to trigger stereo decoders on receivers. If there

2320-460: A prominent Moog synthesizer on the beat, was one of the first disco tracks to use the synthesizer. The rhythm is laid down by prominent, syncopated basslines (with heavy use of broken octaves , that is, octaves with the notes sounded one after the other) played on the bass guitar and by drummers using a drum kit , African/ Latin percussion , and electronic drums such as Simmons and Roland drum modules . In Philly dance and Salsoul disco,

2465-495: A relationship to a penis. The sexual liberation expressed through the rhythm of disco is further represented in the club spaces that disco grew within. In Peter Shapiro 's Modulations: A History of Electronic Music : Throbbing Words on Sound , he discusses eroticism through the technology disco utilizes to create its audacious sound. The music, Shapiro states, is adjunct to "the pleasure-is-politics ethos of post- Stonewall culture." He explains how "mechano-eroticism", which links

2610-417: A stereo/mono switch to allow listening in mono when reception conditions are less than ideal, and most car radios are arranged to reduce the separation as the signal-to-noise ratio worsens, eventually going to mono while still indicating a stereo signal is received. As with monaural transmission, it is normal practice to apply pre-emphasis to the left and right channels before encoding and to apply de-emphasis at

2755-399: A stronger effect. According to Peter Braunstein , the "massive quantities of drugs ingested in discothèques produced the next cultural phenomenon of the disco era: rampant promiscuity and public sex . While the dance floor was the central arena of seduction , actual sex usually took place in the nether regions of the disco: bathroom stalls, exit stairwells , and so on. In other cases

2900-480: A team that included a conductor , copyists , record producers, and mixing engineers . Mixing engineers had an important role in the disco production process because disco songs used as many as 64 tracks of vocals and instruments. Mixing engineers and record producers, under the direction of arrangers, compiled these tracks into a fluid composition of verses, bridges, and refrains, complete with builds and breaks . Mixing engineers and record producers helped to develop

3045-606: A venue were mostly a French invention, imported to the United States with the opening of Le Club , a members-only restaurant and nightclub located at 416 East 55th Street in Manhattan , by French expatriate Olivier Coquelin , on New Year's Eve 1960. Disco music as a genre started as a mixture of music from venues popular among African-Americans , Hispanic and Latino Americans , gay Americans , and Italian Americans in New York City (especially Brooklyn ) and Philadelphia during

3190-493: A young reporter, who happened to be covering the opening of the club, impulsively took control of the record player and introduced the records that he chose to play. Klaus Quirini later claimed to thus have been the world's first nightclub DJ. During the 1960s, discotheque dancing became a European trend that was enthusiastically picked up by the American press. At this time, when the discotheque culture from Europe became popular in

3335-408: Is a form of modulation which conveys information by varying the frequency of a carrier wave ; the older amplitude modulation or AM varies the amplitude of the carrier, with its frequency remaining constant. With FM, frequency deviation from the assigned carrier frequency at any instant is directly proportional to the amplitude of the (audio) input signal, determining the instantaneous frequency of

3480-588: Is achieved by lightly pressing the guitar strings against the fretboard and then quickly releasing them just enough to get a slightly muted poker [sound] while constantly strumming very close to the bridge." Other backing keyboard instruments include the piano , electric organ (during early years), string synthesizers , and electromechanical keyboards such as the Fender Rhodes electric piano, Wurlitzer electric piano, and Hohner Clavinet . Donna Summer 's 1977 song " I Feel Love ", produced by Giorgio Moroder with

3625-525: Is added. VHF radio waves usually do not travel far beyond the visual horizon , so reception distances for FM stations are typically limited to 30–40 miles (50–60 km). They can also be blocked by hills and to a lesser extent by buildings. Individuals with more-sensitive receivers or specialized antenna systems, or who are located in areas with more favorable topography, may be able to receive useful FM broadcast signals at considerably greater distances. The knife edge effect can permit reception where there

3770-401: Is as follows: The normal stereo signal can be considered as switching between left and right channels at 38 kHz, appropriately band-limited. The quadraphonic signal can be considered as cycling through LF, LR, RF, RR, at 76 kHz. Early efforts to transmit discrete four-channel quadraphonic music required the use of two FM stations; one transmitting the front audio channels, the other

3915-422: Is authorized for "hybrid" mode operation, wherein both the conventional analog FM carrier and digital sideband subcarriers are transmitted. The output power of an FM broadcasting transmitter is one of the parameters that governs how far a transmission will cover. The other important parameters are the height of the transmitting antenna and the antenna gain . Transmitter powers should be carefully chosen so that

4060-506: Is claimed that no difference can be heard with most newer receivers. At present, the FCC rules do not allow this mode of stereo operation. In 1969, Louis Dorren invented the Quadraplex system of single station, discrete, compatible four-channel FM broadcasting. There are two additional subcarriers in the Quadraplex system, supplementing the single one used in standard stereo FM. The baseband layout

4205-503: Is defined by the time constant of a simple RC filter circuit. In most of the world a 50  μs time constant is used. In the Americas and South Korea , 75 μs is used. This applies to both mono and stereo transmissions. For stereo, pre-emphasis is applied to the left and right channels before multiplexing . The use of pre-emphasis becomes a problem because many forms of contemporary music contain more high-frequency energy than

4350-581: Is designed to be capable of use alongside ARI despite using identical subcarrier frequencies. In the United States and Canada , digital radio services are deployed within the FM band rather than using Eureka 147 or the Japanese standard ISDB . This in-band on-channel approach, as do all digital radio techniques, makes use of advanced compressed audio . The proprietary iBiquity system, branded as HD Radio ,

4495-429: Is limited to 30 Hz to 15 kHz to protect a 19 kHz pilot signal. The (L−R) signal, which is also limited to 15 kHz, is amplitude modulated onto a 38 kHz double-sideband suppressed-carrier (DSB-SC) signal, thus occupying 23 kHz to 53 kHz. A 19 kHz ± 2 Hz pilot tone , at exactly half the 38 kHz sub-carrier frequency and with a precise phase relationship to it, as defined by

4640-480: Is mainly the preserve of talk radio, news, sports, religious programming, ethnic (minority language) broadcasting and some types of minority interest music. This shift has transformed AM into the "alternative band" that FM once was. (Some AM stations have begun to simulcast on, or switch to, FM signals to attract younger listeners and aid reception problems in buildings, during thunderstorms, and near high-voltage wires. Some of these stations now emphasize their presence on

4785-671: Is no direct line of sight between broadcaster and receiver. The reception can vary considerably depending on the position. One example is the Učka mountain range, which makes constant reception of Italian signals from Veneto and Marche possible in a good portion of Rijeka , Croatia, despite the distance being over 200 km (125 miles). Other radio propagation effects such as tropospheric ducting and Sporadic E can occasionally allow distant stations to be intermittently received over very large distances (hundreds of miles), but cannot be relied on for commercial broadcast purposes. Good reception across

4930-487: Is only suitable for text. A few proprietary systems are used for private communications. A variant of RDS is the North American RBDS or "smart radio" system. In Germany the analog ARI system was used prior to RDS to alert motorists that traffic announcements were broadcast (without disturbing other listeners). Plans to use ARI for other European countries led to the development of RDS as a more powerful system. RDS

5075-521: Is open to anyone who does not carry a prohibition and can put up the appropriate licensing and royalty fees. In 2010 around 450 such licences were issued. Disco music Disco is a genre of dance music and a subculture that emerged in the late 1960s from the United States' urban nightlife scene. Its sound is typified by four-on-the-floor beats, syncopated basslines , string sections , brass and horns , electric piano , synthesizers , and electric rhythm guitars . Discothèques as

5220-454: Is played for dancing, typically equipped with a large dance floor, an elaborate system of flashing coloured lights, and a powerful amplified sound system. " Its earliest example is use as the name of a particular venue in 1952, and other examples date from 1960 onwards. The entry is annotated as "Now somewhat dated". It defines Disco as "A genre of strongly rhythmical pop music mainly intended for dancing in nightclubs and particularly popular in

5365-508: Is related to the transmitter 's RF power, the antenna gain , and antenna height . Interference from other stations is also a factor in some places. In the U.S, the FCC publishes curves that aid in calculation of this maximum distance as a function of signal strength at the receiving location. Computer modelling is more commonly used for this around the world. Many FM stations, especially those located in severe multipath areas, use extra audio compression /processing to keep essential sound above

5510-626: Is stereo, there will typically be a guard band between the upper limit of the DSBSC stereo signal (53 kHz) and the lower limit of any other subcarrier. Digital data services are also available. A 57 kHz subcarrier ( phase locked to the third harmonic of the stereo pilot tone) is used to carry a low-bandwidth digital Radio Data System signal, providing extra features such as station name, alternative frequency (AF), traffic data for satellite navigation systems and radio text (RT). This narrowband signal runs at only 1,187.5 bits per second , thus

5655-402: Is the sum of twice the maximum deviation and twice the maximum modulating frequency. For a transmission that includes RDS this would be 2 × 75 kHz + 2 × 60 kHz  = 270 kHz . This is also known as the necessary bandwidth . Random noise has a triangular spectral distribution in an FM system, with the effect that noise occurs predominantly at the higher audio frequencies within

5800-673: Is usually a multiple of 100 kHz. In most of South Korea , the Americas , the Philippines , and the Caribbean , only odd multiples are used. Some other countries follow this plan because of the import of vehicles, principally from the United States, with radios that can only tune to these frequencies. In some parts of Europe , Greenland , and Africa , only even multiples are used. In the United Kingdom , both odd and even are used. In Italy , multiples of 50 kHz are used. In most countries

5945-586: The CHR/Top 40 format from WEGX , "Eagle 106". CBS decided that WCAU-FM could be more profitable appealing to an older, more desirable demographic of 25-to 54-year-olds. On November 9, 1987, at 7 p.m., after playing " Another One Bites the Dust " by Queen , WCAU-FM returned to the oldies format as WOGL (which stood for "Old Gold"). The first song on WOGL was " Good Golly, Miss Molly " by Little Richard . Eleven hours later, however, 102.1 WIOQ shifted to oldies as well. WOGL had

The individual systems were evaluated for their strengths and weaknesses during field tests in Uniontown, Pennsylvania , using KDKA-FM in Pittsburgh as the originating station. The Crosby system was rejected by the FCC because it was incompatible with existing subsidiary communications authorization (SCA) services which used various subcarrier frequencies including 41 and 67 kHz. Many revenue-starved FM stations used SCAs for "storecasting" and other non-broadcast purposes. The Halstead system

6235-580: The Light Programme , Third Programme and Home Service . These three networks used the sub-band 88.0–94.6 MHz. The sub-band 94.6–97.6 MHz was later used for BBC and local commercial services. However, only when commercial broadcasting was introduced to the UK in 1973 did the use of FM pick up in Britain. With the gradual clearance of other users (notably Public Services such as police, fire and ambulance) and

6380-520: The Step By Step disco dance TV show was launched with the sponsorship support of the Coca-Cola company. Produced in the same studio that Don Cornelius used for the nationally syndicated dance/music television show, Soul Train , Step by Step' s audience grew and the show became a success. The dynamic dance duo of Robin and Reggie led the show. The pair spent the week teaching disco dancing to dancers in

6525-440: The baseband . This can be offset, to a limited extent, by boosting the high frequencies before transmission and reducing them by a corresponding amount in the receiver. Reducing the high audio frequencies in the receiver also reduces the high-frequency noise. These processes of boosting and then reducing certain frequencies are known as pre-emphasis and de-emphasis , respectively. The amount of pre-emphasis and de-emphasis used

6670-575: The call sign W73PH. Beginning the next month the station was issued a series of special authorizations to operate commercially with a temporary antenna, followed by its first full license on March 2, 1943. William Penn Broadcasting also operated AM station WPEN (now WKDN ) in Philadelphia, and on November 1, 1943, W73PH was assigned the WPEN-FM call sign. After the FCC created the current FM broadcast band on June 27, 1945, William Penn Broadcasting applied to

6815-539: The hippies informed proto-disco music like MFSB 's album Love Is the Message . Partly through the success of Jimi Hendrix , psychedelic elements that were popular in rock music of the late 1960s found their way into soul and early funk music and formed the subgenre psychedelic soul . Examples can be found in the music of the Chambers Brothers , George Clinton with his Parliament-Funkadelic collective, Sly and

6960-490: The recording studio . Larry Levan, for example, was a prolific record producer as well as a DJ. Because record sales were often dependent on dance floor play by DJs in the nightclubs, DJs were also influential in the development and popularization of certain types of disco music being produced for record labels. In the early years, dancers in discos danced in a "hang loose" or "freestyle" approach. At first, many dancers improvised their own dance styles and dance steps. Later in

7105-466: The "Hot Hits" format. WCAU-FM found a great deal of success with this programming for much of the mid-1980s, although the original "Fusion" jingles from TM were dropped in the summer of 1982 and replaced with a package from JAM to increase appeal to older listeners. Some notable DJs on the station in this period included Paul Barsky , Rich Hawkins, Billy Burke, Terry Young and Christy Springfield. In 1987, WCAU-FM found itself with stiff competition in

7250-468: The "disco sound" by creating a distinctive-sounding, sophisticated disco mix . Early records were the "standard" three-minute version until Tom Moulton came up with a way to make songs longer so that he could take a crowd of dancers at a club to another level and keep them dancing longer. He found that it was impossible to make the 45-RPM vinyl singles of the time longer, as they could usually hold no more than five minutes of good-quality music. With

7395-521: The 1960s, the Motown record label developed its own approach, described as having "1) simply structured songs with sophisticated melodies and chord changes, 2) a relentless four-beat drum pattern, 3) a gospel use of background voices, vaguely derived from the style of the Impressions , 4) a regular and sophisticated use of both horns and strings, 5) lead singers who were half way between pop and gospel music, 6)

The station experimented briefly with a format called "Mellow Rhythm" at this time, hosted primarily by Dr. Perri Johnson (now a music therapist in Los Angeles ). Program consultant Mike Joseph was brought into WCAU-FM in April 1981 to develop a new format to replace the struggling "Mellow Rhythm". Joseph recommended that

The talk radio programming of sister station WPHT is simulcast on its HD3 subchannel, while the programming on its HD4 subchannel was all related to Philadelphia Phillies baseball . The HD4 subchannel has since been turned off. Prior to 2018, the station played Christmas music during

7975-600: The 85th floor of the Empire State Building in New York City . These FM multiplex transmissions started in November 1934 and consisted of the main channel audio program and three subcarriers : a fax program, a synchronizing signal for the fax program and a telegraph order channel. These original FM multiplex subcarriers were amplitude modulated. Two musical programs, consisting of both the Red and Blue Network program feeds of

8120-638: The FCC announced the reassignment of the FM band to 90 channels from 88–106 MHz (which was soon expanded to 100 channels from 88–108 MHz). This shift, which the AM-broadcaster RCA had pushed for, made all the Armstrong-era FM receivers useless and delayed the expansion of FM. In 1961 WEFM (in the Chicago area) and WGFM (in Schenectady, New York ) were reported as the first stereo stations. By

8265-486: The FCC for a construction permit on January 21, 1946, to install a new transmitter and antenna for operation on 99.5 MHz, and the FCC approved this application on October 24, 1946. The station's license and construction permit were voluntarily assigned to the Philadelphia Record Company, owners of AM station WCAU (now WPHT ) in Philadelphia, on November 28, 1947. This was effective December 18, 1947, and

8410-402: The FCC granted WCAU, Inc. a construction permit to relocate the station's transmitter and antenna to the Roxborough section of Philadelphia. The station's license was renewed by the FCC with the new facilities on October 19, 1954. The FCC granted a voluntary assignment of the station's license to Columbia Broadcasting System, Inc. on July 23, 1958. Until 1966, WCAU-FM simulcast the middle of

The original Dorren Quadraplex System outperformed all

8700-511: The FM band.) The medium wave band (known as the AM band because most stations using it employ amplitude modulation) was overcrowded in western Europe, leading to interference problems and, as a result, many MW frequencies are suitable only for speech broadcasting. Belgium , the Netherlands , Denmark and particularly Germany were among the first countries to adopt FM on a widespread scale. Among

8845-969: The FM radio band from 87.5-108.0 MHz to 76.1-108.0 MHz to enable the migration of AM radio stations in Brazilian capitals and large cities. FM broadcasting began in the late 1930s, when it was initiated by a handful of early pioneer experimental stations, including W1XOJ/W43B/WGTR (shut down in 1953) and W1XTG/ WSRS , both transmitting from Paxton, Massachusetts (now listed as Worcester, Massachusetts ); W1XSL/W1XPW/W65H/WDRC-FM/WFMQ/WHCN , Meriden, Connecticut; and W2XMN , KE2XCC , and WFMN , Alpine, New Jersey (owned by Edwin Armstrong himself, closed down upon Armstrong's death in 1954). Also of note were General Electric stations W2XDA Schenectady and W2XOY New Scotland, New York—two experimental FM transmitters on 48.5 MHz—which signed on in 1939. The two began regular programming, as W2XOY, on November 20, 1940. Over

By the late 1970s, most major U.S. cities had thriving disco club scenes, and DJs would mix dance records at clubs such as Studio 54 in Manhattan , a venue popular among celebrities . Nightclub-goers often wore expensive, extravagant outfits, consisting predominantly of loose, flowing pants or dresses for ease of movement while dancing. There

Other dance marathons took place afterward and Roberts held the world record for disco dancing for a short period of time. Some notable professional dance troupes of the 1970s included Pan's People and Hot Gossip . For many dancers, a key source of inspiration for 1970s disco dancing was the film Saturday Night Fever (1977). Further influence came from

In April 1935, the AM subcarriers were replaced by FM subcarriers, with much improved results. The first FM subcarrier transmissions emanating from Major Armstrong's experimental station KE2XCC at Alpine, New Jersey occurred in 1948. These transmissions consisted of two-channel audio programs, binaural audio programs and

As New York state had laws against homosexual behavior in public, including dancing with a member of the same sex, the eroticism of disco served as resistance and an expression of sexual freedom. He uses Donna Summer's singles " Love to Love You Baby " (1975) and " I Feel Love " (1977) as examples of the ever-present relationship between the synthesized bass lines and backgrounds to

Notable U.S. disco DJs include Francis Grasso of The Sanctuary, David Mancuso of The Loft , Frankie Knuckles of the Chicago Warehouse , Larry Levan of the Paradise Garage , Nicky Siano of The Gallery , Walter Gibbons , Karen Mixon Cook , Jim Burgess , John "Jellybean" Benitez , Richie Kulala of Studio 54 , and Rick Salsalini. Some DJs were also record producers who created and produced disco songs in

10295-535: The capital area's gay and straight college students in the late '70s. By 1979 there were 15,000-20,000 disco nightclubs in the US, many of them opening in suburban shopping centers, hotels, and restaurants. The 2001 Club franchises were the most prolific chain of disco clubs in the country. Although many other attempts were made to franchise disco clubs, 2001 was the only one to successfully do so in this time frame. Powerful, bass-heavy, hi-fi sound systems were viewed as

10440-560: The cha cha ". The pioneer of disco dance instruction was Karen Lustgarten in San Francisco in 1973. Her book The Complete Guide to Disco Dancing (Warner Books 1978) was the first to name, break down and codify popular disco dances as dance forms and distinguish between disco freestyle, partner, and line dances. The book topped the New York Times bestseller list for 13 weeks and was translated into Chinese, German, and French. In Chicago,

10585-557: The chest. Men often wore Pierre Cardin suits, three piece suits with a vest, and double-knit polyester shirt jackets with matching trousers known as the leisure suit . Men's leisure suits were typically form-fitted to some parts of the body, such as the waist and bottom while the lower part of the pants were flared in a bell bottom style, to permit freedom of movement. During the disco era, men engaged in elaborate grooming rituals and spent time choosing fashion clothing, activities that would have been considered "feminine" according to

10730-431: The country is one of the main advantages over DAB/+ radio . This is still less than the range of AM radio waves, which because of their lower frequencies can travel as ground waves or reflect off the ionosphere , so AM radio stations can be received at hundreds (sometimes thousands) of miles. This is a property of the carrier wave's typical frequency (and power), not its mode of modulation. The range of FM transmission

10875-418: The dance and fashion aspects of the disco club scene, there was also a thriving club drug subculture , particularly for drugs that would enhance the experience of dancing to the loud, bass-heavy music and the flashing colored lights, such as cocaine (nicknamed "blow"), amyl nitrite (" poppers "), and the "... other quintessential 1970s club drug Quaalude , which suspended motor coordination and gave

11020-413: The dancers wanted, transitioning from one song to another with a DJ mixer and using a microphone to introduce songs and speak to the audiences. Other equipment was added to the basic DJ setup, providing unique sound manipulations, such as reverb , equalization, and echo effects unit . Using this equipment, a DJ could do effects such as cutting out all but the bassline of a song and then slowly mixing in

11165-482: The dancing, sex, and other embodied movements that contributed to the corporeal vibrations within the Sanctuary. It supports the argument that disco music took a role in facilitating this sexual liberation that was experienced in the discotheques. The recent legalization of abortion and the introduction of antibiotics and the pill facilitated a culture shift around sex from one of procreation to pleasure and enjoyment. Thus

11310-415: The disco became a kind of 'main course' in a hedonist's menu for a night out." At The Saint nightclub, a high percentage of the gay male dancers and patrons would have sex in the club; they typically had unprotected sex , because in 1980, HIV-AIDS had not yet been identified. At The Saint, "dancers would elope to an unpoliced upstairs balcony to engage in sex." The promiscuity and public sex at discos

11455-571: The disco clubs. The instructional show aired on Saturday mornings and had a strong following. Its viewers would stay up all night on Fridays so they could be on the set the next morning, ready to return to the disco on Saturday night knowing with the latest personalized steps. The producers of the show, John Reid and Greg Roselli, routinely made appearances at disco functions with Robin and Reggie to scout out new dancing talent and promote upcoming events such as "Disco Night at White Sox Park". In Sacramento, California, Disco King Paul Dale Roberts danced for

11600-675: The disco era, popular dance styles were developed, including the "Bump", "Penguin", "Boogaloo", "Watergate", and "Robot". By October 1975 the Hustle reigned. It was highly stylized, sophisticated, and overtly sexual. Variations included the Brooklyn Hustle, New York Hustle , and Latin Hustle . During the disco era, many nightclubs would commonly host disco dance competitions or offer free dance lessons. Some cities had disco dance instructors or dance schools, which taught people how to do popular disco dances such as "touch dancing", "the hustle", and "

11745-515: The effects of these innovations in venues such as the Garage." Typical lighting designs for disco dance floors include multi-colored lights that swirl around or flash to the beat, strobe lights , an illuminated dance floor , and a mirror ball . Disco-era disc jockeys (DJs) would often remix existing songs using reel-to-reel tape machines , and add in percussion breaks, new sections, and new sounds. DJs would select songs and grooves according to what

11890-450: The end of the 1960s, musicians, and audiences from the Black, Italian, and Latino communities adopted several traits from the hippie and psychedelia subcultures. They included using music venues with a loud, overwhelming sound, free-form dancing, trippy lighting, colorful costumes, and the use of hallucinogenic drugs. In addition, the perceived positivity, lack of irony, and earnestness of

12035-441: The entire body rather than the obvious erotic parts of the body. The New York nightclub The Sanctuary under resident DJ Francis Grasso is a prime example of this sexual liberty. In their history of the disc jockey and club culture, Bill Brewster and Frank Broughton describe the Sanctuary as "poured full of newly liberated gay men, then shaken (and stirred) by a weighty concoction of dance music and pharmacoia of pills and potions,

12180-553: The extension of the FM band to 108.0 MHz between 1980 and 1995, FM expanded rapidly throughout the British Isles and effectively took over from LW and MW as the delivery platform of choice for fixed and portable domestic and vehicle-based receivers. In addition, Ofcom (previously the Radio Authority) in the UK issues on demand Restricted Service Licences on FM and also on AM (MW) for short-term local-coverage broadcasting which

12325-571: The first discotheque and to have been the first club DJ in 1953 in the "Whisky à Go-Go" in Paris. She installed a dance floor with colored lights and two turntables so she could play records without having a gap in the music. In October 1959, the owner of the Scotch Club in Aachen, West Germany chose to install a record player for the opening night instead of hiring a live band. The patrons were unimpressed until

12470-475: The formula below, is also generated. The pilot is transmitted at 8–10% of overall modulation level and used by the receiver to identify a stereo transmission and to regenerate the 38 kHz sub-carrier with the correct phase. The composite stereo multiplex signal contains the Main Channel (L+R), the pilot tone, and the (L−R) difference signal. This composite signal, along with any other sub-carriers, modulates

12615-627: The frequency of 1980s and 1990s hits per day and is also adding music from the 2000s. On April 28, 2022, at 8:30 a.m., after playing " Got My Mind Set on You " by George Harrison and going into a commercial stopset, the station began a half-hour stunt with songs that featured the word "big" in the title or artist name, such as " To Be with You " by Mr. Big , " Big Pimpin' " by Jay Z featuring UGK , " Mr. Big Stuff " by Jean Knight , " Big Girls Don't Cry " by Fergie and " Big Me " by Foo Fighters . At 9:00, WOGL relaunched as "Big 98.1", readjusting their classic hits format to focus primarily on songs from

12760-482: The frequency of the pilot tone. Slight variations in the peak deviation may occur in the presence of other subcarriers or because of local regulations. Another way to look at the resulting signal is that it alternates between left and right at 38 kHz, with the phase determined by the 19 kHz pilot signal. Most stereo encoders use this switching technique to generate the 38 kHz subcarrier, but practical encoder designs need to incorporate circuitry to deal with

12905-662: The gender stereotypes of the era. Women dancers wore glitter makeup, sequins , or gold lamé clothing that would shimmer under the lights. Bold colors were popular for both genders. Platform shoes and boots for both genders and high heels for women were popular footwear. Necklaces and medallions were a common fashion accessory . Less commonly, some disco dancers wore outlandish costumes, dressed in drag , covered their bodies with gold or silver paint, or wore very skimpy outfits leaving them nearly nude; these uncommon get-ups were more likely to be seen at invitation-only New York City loft parties and disco clubs. In addition to

13050-414: The help of José Rodriguez, his remaster/mastering engineer, he pressed a single on a 10" disc instead of 7". They cut the next single on a 12" disc, the same format as a standard album. Moulton and Rodriguez discovered that these larger records could have much longer songs and remixes. 12" single records , also known as " Maxi singles ", quickly became the standard format for all DJs of the disco genre. By

13195-505: The high import costs of FM radio receivers, transmissions were carried out in circuit closed to businesses and stores, which played ambient music offered by radio. Until 1976, Rádio Imprensa was the only station operating in FM in Brazil. From the second half of the 1970s onwards, FM radio stations began to become popular in Brazil, causing AM radio to gradually lose popularity. In 2021, the Brazilian Ministry of Communications expanded

13340-551: The holiday season; this practice was discontinued after WBEB , which also broadcasts Christmas music during the season, was acquired by Entercom (forerunner of Audacy). On January 13, 1942, the Federal Communications Commission (FCC) granted the William Penn Broadcasting Company a construction permit for a new FM station on 47.3 MHz on the original 42-50 MHz FM broadcast band, with

13485-601: The late 1960s to the mid-to-late 1970s. Disco can be seen as a reaction by the 1960s counterculture to both the dominance of rock music and the stigmatization of dance music at the time. Several dance styles were developed during the period of 70s disco's popularity in the United States, including "the Bump ", "the Hustle ", "the Watergate", and "the Busstop". During the 1970s, disco music

13630-517: The late 1960s, FM had been adopted for broadcast of stereo "A.O.R.—' Album Oriented Rock ' Format", but it was not until 1978 that listenership to FM stations exceeded that of AM stations in North America. In most of the 70s FM was seen as highbrow radio associated with educational programming and classical music, which changed during the 1980s and 1990s when Top 40 music stations and later even country music stations largely abandoned AM for FM. Today AM

13775-496: The late 1970s, Dolby FM was similar to Dolby B but used a modified 25 μs pre-emphasis time constant and a frequency selective companding arrangement to reduce noise. The pre-emphasis change compensates for the excess treble response that otherwise would make listening difficult for those without Dolby decoders. A similar system named High Com FM was tested in Germany between July 1979 and December 1981 by IRT . It

13920-466: The late 1970s, Studio 54 in Midtown Manhattan was arguably the best-known nightclub in the world. This club played a major formative role in the growth of disco music and nightclub culture in general. It was operated by Steve Rubell and Ian Schrager and was notorious for the hedonism that went on within: the balconies were known for sexual encounters and drug use was rampant. Its dance floor

14065-755: The late 1970s, most major US cities had thriving disco club scenes. The largest scenes were most notably in New York City but also in Philadelphia , San Francisco , Miami , and Washington, D.C. The scene was centered on discotheques , nightclubs and private loft parties. In the 1970s, notable discos included " Crisco Disco ", "The Sanctuary", "Leviticus", " Studio 54 ", and " Paradise Garage " in New York, "Artemis" in Philadelphia, "Studio One" in Los Angeles, "Dugan's Bistro" in Chicago, and "The Library" in Atlanta. In

14210-578: The latter is still its own public company, effectively separating WOGL and its sister stations from KYW-TV and WPSG-TV . ** = Audacy operates pursuant to a local marketing agreement with Martz Communications Group . FM broadcasting Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum . Usually 87.5 to 108.0 MHz is used, or some portion of it, with few exceptions: The frequency of an FM broadcast station (more strictly its assigned nominal center frequency)

14355-462: The left (L) and right (R) channels are algebraically encoded into sum (L+R) and difference (L−R) signals. A mono receiver will use just the L+R signal so the listener will hear both channels through the single loudspeaker. A stereo receiver will add the difference signal to the sum signal to recover the left channel, and subtract the difference signal from the sum to recover the right channel. The (L+R) signal

14500-537: The main frequency as far back as WOGL's launch in 1987. From the late 1980s through the early 1990s, WOGL used jingles from Frank Gari Productions, Otis Connor, and TM Studios . From the mid-1990s through the early 2000s, the station used the Do It Again jingle package by JAM Creative Productions and the Super Hits package by Tony Griffin, both of which were also used by sister station WCBS-FM . From 2003 to 2017,

14645-476: The maximum permitted carrier deviation is invariably ±75 kHz, although a little higher is permitted in the United States when SCA systems are used. For a monophonic broadcast, again the most common permitted maximum deviation is ±75 kHz. However, some countries specify a lower value for monophonic broadcasts, such as ±50 kHz. The bandwidth of an FM transmission is given by the Carson bandwidth rule which

14790-427: The maximum permitted frequency error of the unmodulated carrier is specified, which typically should be within 2 kHz of the assigned frequency. There are other unusual and obsolete FM broadcasting standards in some countries, with non-standard spacings of 1, 10, 30, 74, 500, and 300 kHz. To minimise inter-channel interference, stations operating from the same or nearby transmitter sites tend to keep to at least

14935-555: The mid to late 1970s.", with use from 1975 onwards, describing the origin of the word as a shortened form of discotheque . In the summer of 1964, a short sleeveless dress called the "discotheque dress" was briefly very popular in the United States. The earliest known use for the abbreviated form "disco" described this dress and has been found in The Salt Lake Tribune on July 12, 1964; Playboy magazine used it in September of

15080-799: The music and dance style of such films as Fame (1980), Disco Dancer (1982), Flashdance (1983), and The Last Days of Disco (1998). Interest in disco dancing also helped spawn dance competition TV shows such as Dance Fever (1979). Disco fashions were very trendy in the late 1970s. Discothèque-goers often wore glamorous, expensive, and extravagant fashions for nights out at their local disco club. Some women would wear sheer, flowing dresses, such as Halston dresses, or loose, flared pants. Other women wore tight, revealing, sexy clothes, such as backless halter tops , disco pants , "hot pants", or body-hugging spandex bodywear or "catsuits". Men would wear shiny polyester Qiana shirts with colorful patterns and pointy, extra wide collars, preferably open at

15225-469: The musical styles which prevailed at the birth of FM broadcasting. Pre-emphasizing these high-frequency sounds would cause excessive deviation of the FM carrier . Modulation control (limiter) devices are used to prevent this. Systems more modern than FM broadcasting tend to use either programme-dependent variable pre-emphasis; e.g., dbx in the BTSC TV sound system, or none at all. Pre-emphasis and de-emphasis

15370-536: The next few years this station operated under the call signs W57A, W87A and WGFM, and moved to 99.5 MHz when the FM band was relocated to the 88–108 MHz portion of the radio spectrum. General Electric sold the station in the 1980s. Today this station is WRVE . Other pioneers included W2XQR/W59NY/WQXQ/WQXR-FM , New York; W47NV/WSM-FM Nashville, Tennessee (signed off in 1951); W1XER/W39B/WMNE , with studios in Boston and later Portland, Maine, but whose transmitter

15515-468: The off-beat, and a heavy, syncopated bass line. A recording error in the 1975 song " Bad Luck " by Harold Melvin & the Blue Notes where Earl Young 's hi-hat was too loud in the recording is said to have established loud hi-hats in disco. Other Latin rhythms such as the rhumba, the samba, and the cha-cha-cha are also found in disco recordings, and Latin polyrhythms , such as a rhumba beat layered over

15660-565: The others and was chosen as the national standard for Quadraphonic FM broadcasting in the United States. The first commercial FM station to broadcast quadraphonic program content was WIQB (now called WWWW-FM ) in Ann Arbor / Saline, Michigan under the guidance of Chief Engineer Brian Jeffrey Brown. Various attempts to add analog noise reduction to FM broadcasting were carried out in the 1970s and 1980s: A commercially unsuccessful noise reduction system used with FM radio in some countries during

15805-444: The rear channels. A breakthrough came in 1970 when KIOI ( K-101 ) in San Francisco successfully transmitted true quadraphonic sound from a single FM station using the Quadraplex system under Special Temporary Authority from the FCC . Following this experiment, a long-term test period was proposed that would permit one FM station in each of the top 25 U.S. radio markets to transmit in Quadraplex. The test results hopefully would prove to

15950-551: The reasons for this were: Public service broadcasters in Ireland and Australia were far slower at adopting FM radio than those in either North America or continental Europe . Hans Idzerda operated a broadcasting station, PCGG , at The Hague from 1919 to 1924, which employed narrow-band FM transmissions. In the United Kingdom the BBC conducted tests during the 1940s, then began FM broadcasting in 1955, with three national networks:

16095-478: The receiver after decoding. In the U.S. around 2010, using single-sideband modulation for the stereo subcarrier was proposed. It was theorized to be more spectrum-efficient and to produce a 4 dB s/n improvement at the receiver, and it was claimed that multipath distortion would be reduced as well. A handful of radio stations around the country broadcast stereo in this way, under FCC experimental authority. It may not be compatible with very old receivers, but it

16240-570: The required area is covered without causing interference to other stations further away. Practical transmitter powers range from a few milliwatts to 80 kW. As transmitter powers increase above a few kilowatts, the operating costs become high and only viable for large stations. The efficiency of larger transmitters is now better than 70% (AC power in to RF power out) for FM-only transmission. This compares to 50% before high efficiency switch-mode power supplies and LDMOS amplifiers were used. Efficiency drops dramatically if any digital HD Radio service

16385-524: The result is a festivaly of carnality." The Sanctuary was the "first totally uninhibited gay discotheque in America" and while sex was not allowed on the dancefloor, the dark corners, bathrooms. and hallways of the adjacent buildings were all utilized for orgy-like sexual engagements. By describing the music, drugs, and liberated mentality as a trifecta coming together to create the festival of carnality, Brewster and Broughton are inciting all three as stimuli for

16530-470: The road music heard on AM 1210 WCAU . Along with other CBS FM stations, WCAU-FM began airing "The Young Sound," a prerecorded format of instrumental easy listening songs based on contemporary hits. In the fall of 1970, WCAU-FM replaced "The Young Sound" with an automated oldies format. For prerecorded announcements, the station used the voice of Jim Nettleton, a disc jockey on top-rated WABC in New York City . Prior to working for WABC, Jim Nettleton

16675-596: The same meaning in English in the 1950s. "Discothèque" became used in French for a type of nightclub in Paris, after they had resorted to playing records during the Nazi occupation in the early 1940s. Some clubs used it as their proper name. In 1960, it was also used to describe a Parisian nightclub in an English magazine. The Oxford English Dictionary defines Discotheque as "A dance hall, nightclub, or similar venue where recorded music

16820-618: The same year to describe Los Angeles nightclubs. Vince Aletti was one of the first to describe disco as a sound or a music genre. He wrote the 13 September 1973 feature article Discotheque Rock '72: Paaaaarty! that appeared in Rolling Stone magazine. The music typically layered soaring, often- reverberated vocals, often doubled by horns, over a background "pad" of electric pianos and "chicken-scratch" rhythm guitars played on an electric guitar . Lead guitar features less frequently in disco than in rock . "The "rooster scratch" sound

16965-401: The sensation that one's arms and legs had turned to ' Jell-O . ' " Quaaludes were so popular at disco clubs that the drug was nicknamed "disco biscuits". Paul Gootenberg states that "[t]he relationship of cocaine to 1970s disco culture cannot be stressed enough..." During the 1970s, the use of cocaine by well-to-do celebrities led to its "glamorization" and to the widely held view that it

17110-452: The simulated sounds of orgasms. Summer's voice echoes in the tracks, and likens them to the drug-fervent, sexually liberated fans of disco who sought to free themselves through disco's "aesthetic of machine sex." Shapiro sees this as an influence that creates sub-genres like hi-NRG and dub -disco, which allowed for eroticism and technology to be further explored through intense synth bass lines and alternative rhythmic techniques that tap into

17255-468: The sound was enriched with solo lines and harmony parts played by a variety of orchestral instruments, such as violin , viola , cello , trumpet , saxophone , trombone , flugelhorn , French horn , English horn , oboe , flute , timpani and synth strings , string section or a full string orchestra . Most disco songs have a steady four-on-the-floor beat set by a bass drum, a quaver or semi-quaver hi-hat pattern with an open hissing hi-hat on

17400-930: The station go Top 40 . On September 22, 1981, at midnight, the new format at WCAU-FM debuted: an all-current-hits, high-energy, jingle -intensive Top 40 sound dubbed " Hot Hits ". Joseph first put Hot Hits on the air in 1977 at WTIC-FM in Hartford, Connecticut , with a significant increase in ratings. Joseph called the station "98 Now". WCAU-FM's ratings showed an immediate improvement, and subsequently, FM stations in major radio markets such as WBBM-FM in Chicago, WHYT in Detroit, WMAR-FM in Baltimore, CKOM in Saskatoon, WFEC in Harrisburg, WNVZ in Norfolk, and KITS in San Francisco picked up

17545-426: The station used jingles from a variety of different JAM packages, most of which were resings of 1970s-80s top 40 station jingles. Since late 2017, the station has been using jingles from Reelworld Productions. On February 2, 2017, CBS agreed to merge CBS Radio with Entercom (now Audacy). The merger was approved on November 9, 2017, and was consummated on November 17. Though CBS shareholders own 72 percent of Entercom,

17690-411: The station's call sign was changed to WCAU-FM the same day. On December 23, 1947, the FCC reassigned the station to 98.1 MHz, modifying the construction permit. The FCC granted a licensee name change from Philadelphia Record Company to WCAU, Inc. on March 3, 1948. The commission granted WCAU, Inc. a new license for the station for operation on 98.1 MHz on September 27, 1949. On December 4, 1953,

17835-462: The switching harmonics. Converting the multiplex signal back into left and right audio signals is performed by a decoder, built into stereo receivers. Again, the decoder can use a switching technique to recover the left and right channels. In addition, for a given RF level at the receiver, the signal-to-noise ratio and multipath distortion for the stereo signal will be worse than for the mono receiver. For this reason many stereo FM receivers include

17980-522: The technology used to create the unique mechanical sound of disco to eroticism, set the genre in a new dimension of reality living outside of naturalism and heterosexuality. Randy Jones and Mark Jacobsen echo this sentiment in BBC Radio's "The Politics of Dancing: How Disco Changed the World," describing the loose, hip-focused dance style as "a new kind of communion" that celebrates the sparks of liberation brought on

18125-462: The transmitted signal. Because transmitted FM signals use significantly more bandwidth than AM signals, this form of modulation is commonly used with the higher ( VHF or UHF ) frequencies used by TV , the FM broadcast band , and land mobile radio systems . The maximum frequency deviation of the carrier is usually specified and regulated by the licensing authorities in each country. For a stereo broadcast,

18270-448: Was a "soft drug". LSD , marijuana , and "speed" (amphetamines) were also popular in disco clubs, and the use of these drugs "...contributed to the hedonistic quality of the dance floor experience." Since disco dances were typically held in liquor licensed - nightclubs and dance clubs , alcoholic drinks were also consumed by dancers; some users intentionally combined alcohol with the consumption of other drugs, such as Quaaludes, for

18415-440: Was a very popular DJ on WFIL from 1966 to 1969 before he was heard on WABC in late 1969. Live air personalities were eventually heard, with Nettleton moving from New York to host middays. The station played the hits from 1955 up to and including some current product. At the end of 1975, the oldies format was replaced by disco music , a hot trend at the time. As disco cooled, the station called its format "Fascinatin' Rhythm". When

18560-565: Was about 2/3 R&B and 1/3 rock and pop, with the rock and pop songs that were played being the big hits typically heard on oldies stations. WOGL played about 15% 1950s, 15% early 1960s, 55% mid-to-late 1960s, 13% 1970s, and 2% 1980s. WOGL aired specialty shows such as the "Hot Lunch Special" request show, "The Weeknight Hall Of Fame," "Top 20 Oldies Countdown," "Elvis & Friends," "The Saturday Night Dance Party," "Brunch With The Beatles," and "Street Corner Sunday" (a Doo Wop music program). In 2001, all specialty shows were dropped. The playlist

18705-571: Was also a thriving drug subculture in the disco scene, particularly for drugs that would enhance the experience of dancing to the loud music and the flashing lights, such as cocaine and quaaludes , the latter being so common in disco subculture that they were nicknamed "disco biscuits". Disco clubs were also associated with promiscuity as a reflection of the sexual revolution of this era in popular history. Films such as Saturday Night Fever (1977) and Thank God It's Friday (1978) contributed to disco's mainstream popularity. Disco declined as

18850-616: Was atop the highest mountain in the northeast United States, Mount Washington , New Hampshire (shut down in 1948); and W9XAO/W55M/WTMJ-FM Milwaukee, Wisconsin (went off air in 1950). A commercial FM broadcasting band was formally established in the United States as of January 1, 1941, with the first fifteen construction permits announced on October 31, 1940. These stations primarily simulcast their AM sister stations, in addition to broadcasting lush orchestral music for stores and offices, classical music to an upmarket listenership in urban areas, and educational programming. On June 27, 1945

18995-518: Was based on the Telefunken High ;Com broadband compander system, but was never introduced commercially in FM broadcasting. Yet another system was the CX -based noise reduction system FMX implemented in some radio broadcasting stations in the United States in the 1980s. FM broadcasting has included subsidiary communications authorization (SCA) services capability since its inception, as it

19140-522: Was decorated with an image of the " Man in the Moon " that included an animated cocaine spoon . The " Copacabana ", another New York nightclub dating to the 1940s, had a revival in the late 1970s when it embraced disco; it would become the setting of a Barry Manilow song of the same name . In Washington, D.C. , large disco clubs such as "The Pier" ("Pier 9") and "The Other Side", originally regarded exclusively as " gay bars ", became particularly popular among

19285-412: Was described as having a " pansexual attitude [that] was revolutionary in a country where up until recently it had been illegal for two men to dance together unless there was a woman present; where women were legally obliged to wear at least one recognizable item of female clothing in public; and where men visiting gay bars usually carried bail money with them." Disco was mostly developed from music that

19430-579: Was developed further, mainly by artists from the United States as well as from Europe . Well-known artists included the Bee Gees , ABBA , Donna Summer , Gloria Gaynor , Giorgio Moroder , Baccara , The Jacksons , Michael Jackson , Boney M , Earth Wind & Fire , Rick James , ELO , Average White Band , Chaka Khan , Chic , KC and the Sunshine Band , Thelma Houston , Sister Sledge , Sylvester , The Trammps , Barry White , Diana Ross , Kool &

19575-595: Was fostered a very sex-positive framework around discotheques. Further, in addition to gay sex being illegal in New York state, until 1973 the American Psychiatric Association classified homosexuality as an illness. This law and classification coupled together can be understood to have heavily dissuaded the expression of queerness in public, as such the liberatory dynamics of discotheques can be seen as having provided space for self-realization for queer persons. David Mancuso's club/house party, The Loft ,

19720-493: Was let go after 14 years with the station. In 2017, Frank Lewis and Bill Zimpfer, co-hosts of WOGL's morning show "The Breakfast Club", were also let go. As of 2018, WOGL no longer plays 1960s and early 1970s music, with its playlist shifting towards focusing on hits from the 1970s through the early 1990s, with a heavy focus on the 1980s. On January 21, 2018, "Street Corner Sunday" was discontinued after 29 years in favor of regular programming. As of April 2022, WOGL has increased

19865-439: Was moved away from soul and Philadelphia-only hits (though a few remained), and moved towards a more traditional playlist as found on other oldies stations. The music was about 70% 1960s, 10% 1950s, 15% 1970s, and 5% 1980s. Scott Walker left the station in 2001. By 2002, some of the specialty shows were brought back, including a modified version of "Street Corner Sunday". While it was strictly doo wop in its previous incarnation, it

20010-404: Was much more costly to produce than many of the other popular music genres from the 1970s. Unlike the simpler, four-piece-band sound of funk , soul music of the late 1960s or the small jazz organ trios , disco music often included a large band, with several chordal instruments (guitar, keyboards, synthesizer), several drum or percussion instruments (drumkit, Latin percussion, electronic drums),

20155-473: Was part of a broader trend towards exploring a freer sexual expression in the 1970s, an era that is also associated with " swingers clubs , hot tubs , [and] key parties ." In his paper, "In Defense of Disco" (1979), Richard Dyer claims eroticism as one of the three main characteristics of disco. As opposed to rock music which has a very phallic centered eroticism focusing on the sexual pleasure of men over other persons, Dyer describes disco as featuring

20300-423: Was popular on the dance floor in clubs that started playing records instead of having a live band. The first discotheques mostly played swing music . Later on, uptempo rhythm and blues became popular in American clubs and northern soul and glam rock records in the UK. In the early 1940s, nightclubs in Paris resorted to playing jazz records during the Nazi occupation. Régine Zylberberg claimed to have started

20445-457: Was rejected due to lack of high frequency stereo separation and reduction in the main channel signal-to-noise ratio. The GE and Zenith systems, so similar that they were considered theoretically identical, were formally approved by the FCC in April 1961 as the standard stereo FM broadcasting method in the United States and later adopted by most other countries. It is important that stereo broadcasts be compatible with mono receivers. For this reason,

20590-574: Was roughly 50% mid and late 1960s and 50% 1970s music. In 2004, the playlist was tightened to about half 1960s and half 1970s. Their slogan also changed to "Greatest Hits of the '60s and '70s." In late 2007 and early 2008, more 1980s music was added to the rotation, and effective July 6, 2008, WOGL's slogan was changed to "The Greatest Hits of the 60s, 70s and 80s," which is also used on sister station WCBS-FM when it returned to an Oldies/Classic Hits format in July 2007. In late 2016, morning co-host Valerie Knight

20735-565: Was seen as another service which licensees could use to create additional income. Use of SCAs was particularly popular in the US, but much less so elsewhere. Uses for such subcarriers include radio reading services for the blind , which became common and remain so, private data transmission services (for example sending stock market information to stockbrokers or stolen credit card number denial lists to stores, ) subscription commercial-free background music services for shops, paging ("beeper") services, alternative-language programming, and providing

20880-407: Was updated to play all types of pre-1964 oldies. In addition, more 1970s music was added and even some 1980s tracks were heard. In 2003, the name "Oldies 98" was downplayed and the station became known as "Motown Soul Rock & Roll: 98.1 WOGL". At that point, the station cut to one 1950s song per hour and one pre-'64 song per hour. It also played a couple of 1980s songs per hour. The rest of the music

21025-446: Was used in the earliest days of FM broadcasting. According to a BBC report from 1946, 100 μs was originally considered in the US, but 75 μs subsequently adopted. Long before FM stereo transmission was considered, FM multiplexing of other types of audio-level information was experimented with. Edwin Armstrong, who invented FM, was the first to experiment with multiplexing, at his experimental 41 MHz station W2XDG located on
