1960s: Early roots; easy listening and soft rock concentrated on romantic readings of jazz and pop standards for the adult contemporary audience of the 1960s and 1970s. 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 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.
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. 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." The song was
George Michael's first solo single. On April 7, 1979, the Easy Listening chart officially became known as Adult Contemporary, 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. band logo. Their 1984 single "
You're the Inspiration" from their fourteenth studio album
Chicago 17 (1984) became synonymous with the soft rock radio format. 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 's self-titled English-language album released in 1999 had singles that crossed over to the AC charts. 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 format—many 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 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 – present: AC music goes mainstream and mainstream music goes AC 's singles and albums topped the AC charts in the 2000s and 2010s. During 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 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, 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. 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. 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. 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 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 the
Jonas Brothers and
Halsey began to be featured on AC stations more than on top 40 stations. ==Adult contemporary formats==
