The exact assemblage of adult contemporary music is influenced primarily by the popular music trends of a given era, and which trends and genres appeal more heavily to youth and young adults. It was originally established as a continuation of the easy listening and soft rock sounds from the 1960s and 1970s, acting as a counterbalance for the hard rock of the era, and later heavy metal and hip-hop: it initially focused on songs with varying degrees of influence from easy listening, pop, soul, R&B, quiet storm, and rock.
In the 1990s, adult contemporary began to accommodate a hotter sound more inclusive of contemporary pop, and developed sub-categories devoted towards specific genres.
In radio broadcasting, adult contemporary formats typically target the demographic of adults 25โ44, as they are favored among advertisers. They are differentiated primarily by their playlists, with "hot AC" stations usually focusing on uptempo mainstream music (including dance-pop, contemporary R&B, as well as pop, alternative, indie, and soft rock, while excluding more specialized types of hip-hop, hard rock, teen pop, and electronic dance music that do not appeal as strongly to older audiences), "mainstream AC" having a balance between current music and established hits from past decades, and "soft AC" having a more conservative sound.
AC stations may also feature pop hits from previous decades that are considered nostalgic by the target audience.
Other sub-categories of AC have also emerged, including rhythmic adult contemporary (which focuses particularly on dance music), urban adult contemporary (which focuses on R&B and soul music), and Christian adult contemporary.
History
1960s: Early roots; easy listening and soft rock
Adult contemporary traces its roots to the 1960s easy listening format, which adopted a 70โ80% instrumental to 20โ30% vocal mix. A few offered 90% instrumentals, and a handful were entirely instrumental. The easy listening format, as it 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, 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 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 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 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 a similar "lite" format by choosing certain tracks (both hit singles and album cuts) of popular artists.
1970s: Soft rock forms as a radio format
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 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 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 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 also 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 the reformed Fleetwood Mac, whose Rumours (1977) was one of the best-selling albums 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 for different demographic groups, such as disco and hard rock, began to emerge in the late 1970s. This led to specialized radio stations that played specific genres of music; further, radio stations generally followed the evolution of artists in those genres.
1980s: Adult contemporary succeeds as radio format
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 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, 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 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 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 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 the Hot 100.
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 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.
1990s: Subgenre formations/radio crossovers
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 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 formatโmany AC stations carried 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 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 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 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 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 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.
2000s โ present: AC music goes mainstream and mainstream music goes AC
During the 2000s, the AC market gained an increased presence in the music industry, as its radio formats were popular nationwideโSmooth 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 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 Bublรฉ'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 the 2000s, country music/countrypolitan musicians such as Kelly Clarkson, Clay Aiken, 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 the success of AC in the 2000s was the 25โ34 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 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 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 was a result of the changes on the broadcasting landscape following the Great 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 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 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 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.
