The members had gone on to solo careers in the entertainment industry after indefinitely discontinuing group activity in 2005 following the departure of a member. However, they regrouped as a quintet and made a comeback in July 2014.

History


Beginnings

In 1997, Park Joon-hyung flew to South Korea with the goal of creating a group which blended Western and Asian influences. He recruited his cousin Danny Ahn and the latter's friend Son Ho-young, Yoon Kye-sang and Kim Tae-woo (singer), Kim Tae-woo were later recruited through auditions. Their formation was fraught with difficulties from the beginning as their talent management company EBM (which merged into Sidus Pictures, Sidus and again split to become iHQ (company), iHQ (SidusHQ) in 2005) had been affected by the 1997 Asian financial crisis and was forced to cut financial funding for its trainees. After over a year, executives allowed them to continue with the project due to their persistence and introduced singer-songwriter and JYP Entertainment founder Park Jin-young to be their producer and mentor. Kim Sun-a left to pursue acting and Kim Tae-woo (singer), Kim Tae-woo, who was still a high school student, was the final member added, joining the group in July 1998. The group was to be called "GOT6", but their name was changed to g.o.d (Groove Over Dose) instead when it became a five-member boy band; Park Jin-young has since revealed that GOT7's group name originated from GOT6.


1999: Debut

The group made their debut appearance on January 13, 1999, performing "To Mother" (어머님께), the title track of their Chapter 1 (g.o.d album), first album, live on the Seoul Broadcasting System, SBS late night show ''One Night of TV Entertainment'' (:ko:한밤의 TV연예, ko). The music video for the song featured actor Jang Hyuk. Although it has since become one of their most famous songs, the initial televised performance did not earn a positive response from those in the music industry. g.o.d also gained attention for their "boys next door" persona and vocal talent, a stark contrast to the trend of the era which was largely focused on groups with kkonminam, visually appealing members and highly sophisticated and energetic choreography. They released their Chapter 2 (g.o.d album), second album at the end of the year and it garnered a much better response and also earned the group their first ever #1 win on a Music programs of South Korea, music program.


2000–2006: Mainstream success, Kye-sang's departure, and hiatus

In January 2000, the five members appeared in a reality TV series, called ''g.o.d's Baby Diaries'' (:ko:god의 육아일기, ko), which aired as a segment of Munhwa Broadcasting Corporation, MBC's "Achieve the Goal Saturday" (:ko:목표달성! 토요일, ko) weekend program. The members acted as a family to take care of an eleventh-month old boy named Han Jae-min. Every one of them had a duty (i.e. Son Ho Young acted as 'mommy' and Park Joon Hyung as 'daddy'). The show was popular due to the fact that it was the first time an idol group had starred in their own reality show and its high ratings reportedly forced the sketch comedy show ''Gag Concert'', which aired at the same time on MBC's competitor broadcaster Korean Broadcasting System, KBS, to switch time slots. Just a year after debuting, g.o.d saw success with the release of their Chapter 3 (g.o.d album), third album, which sold over a million copies. Its promoted track "Lies" (거짓말) dominated the #1 spot on Music programs of South Korea, music programs and also won the ''Daesang'' ("Grand Prize") at the KBS Song Festival, KBS Music Awards. Following the success of their third album, g.o.d held their first national tour beginning in February 2001 and became only the second K-pop group (after H.O.T. (band), H.O.T.) to hold a concert in the largest sports venue in South Korea, the Seoul Olympic Stadium. In November that year, g.o.d launched their fourth album ''Chapter 4 (g.o.d album), Chapter 4'', their second album to hit a million in sales. The title track "Road" (길) topped the rankings on several music shows and has since become a classic hit. The album won the Disk ''Daesang'' (Grand Prize) at the 16th Golden Disc Awards. Additionally, the group achieved a rare feat by sweeping the ''Daesang'' awards at the respective year-end music awards run by the country's three major broadcasting stations KBS, SBS and MBC. The group nearly broke up in September 2001 after Park was discovered to be dating, which was considered to be taboo for most pop stars in South Korea at that time. Their management announced, without informing him or the other group members, that he was to leave the group and g.o.d would continue as a quartet. It was met with strong objection from fans, who repeatedly signed petitions, threatened to boycott concerts and stated their intentions of returning purchased merchandise for refunds. Ahn, Yoon, Son and Kim held their own press conference, without the knowledge of their management, to show their support for Park. By November, their management eventually backed down. Having established themselves as the country's best selling idol group of 2001, g.o.d was invited to perform at the MTV Asia Awards 2002, inaugural MTV Asia Awards held in Singapore as the Korean representative and was nominated for the Favorite Artist Award (Korea). While in Singapore, the group was interviewed by ''Time (magazine), Time'' magazine and featured on the cover of the Asian edition for July 29. However, the article they were featured in was met with criticism by Korean music critics, local media and g.o.d's management agency SidusHQ as the author used a misquote attributed to Yoon Kye-sang to segue into an opinion editorial about corruption within the K-pop industry rather than focus on g.o.d as one of the country's most popular pop groups. They were chosen as the country's representative artistes to be featured in the 2002 FIFA World Cup official album ''Fever Pitch (album), Fever Pitch'', for which they recorded the song "True East Side". In July they took a break from television promotions and began their "100-day Human Concert" series where all the shows were sold out and each day had a different theme. Yoon left the group in 2004 and g.o.d switched to JYP Entertainment after their group contract with SidusHQ expired. They continued promoting as a quartet, releasing another two more albums. They went on hiatus from 2006 after holding their last concert in December 2005. Various media outlets and sources have described them as having disbanded between 2006 and 2014. However, the remaining members stated that they chose not use the term "disbanding" as they had promised fans they would reunite as a five-piece at some point in the future. All members remained in the entertainment industry: Park returned to the United States to pursue acting, Ahn hosted KBS Cool FM's ''Kiss the Radio'' while Son and Kim continued as singers and musical actors. The remaining four members unofficially reunited to perform in 2012 at the Korean Music Festival in Los Angeles and on SBS MTV's ''The Stage Big Pleasure''.


2014–present: Reunion

Beginning in 2013 there was already speculation that the members of g.o.d were discussing the possibility of reuniting. Following Yoon Kye-sang's confirmation to rejoin the group and lengthy discussion and organization with the members' individual managements, they recommenced group activities under their original management agency SidusHQ. On May 3, 2014 their 15th anniversary concert was announced through a TV advertisement which aired on Korean cable channel jTBC, followed by confirmation from their management agency. Despite the low-key announcement and the group's refusal to promote on Music programs of South Korea, music programs, their comeback received extensive media coverage and became a trending topic on the internet within South Korea as they were the first inactive K-pop idol group to make a comeback with all of its original members. The album ''Chapter 8 (g.o.d album), Chapter 8'' was released on July 8, 2014. Several songs were pre-released as teasers for their official comeback tour. The pre-released singles, "The Lone Duckling" (also "The Ugly Duckling") (미운 오리 새끼) and "Sky Blue Promise" (하늘색 약속), both achieved "K-pop#Industry-specific expressions, all kills" in the digital charts. The music videos for "Saturday Night", which contained references of their hit "Friday Night", and the ballad "Story of Our Lives" were uploaded on YouTube. The album was repackaged and released in October as the "Thank You" edition and included a new song "Wind" (바람), whose lyrics were written by Yoon to express his gratitude to fans. The group began their 15th anniversary tour on July 12, 2014 at Seoul Sports Complex, Jamsil Sports Complex with around 14,000 fans in attendance. It was their first concert as a quintet in 12 years. Initially they had planned to hold two concerts over two days in Seoul but extended it to eight more dates in four other cities due to popular demand. They also made their first televised performance together in 12 years on September 5 as exclusive guests on ''You Hee-yeol's Sketchbook'', the only guests who have been granted the honor. They concluded their national tour with an encore concert in October at the 40,000-capacity Seoul Olympic Stadium, the second time they have held a sold-out concert at the venue. In November they extended their tour overseas for the time, holding concerts at the Staples Center in Los Angeles, California and Prudential Center in Newark, New Jersey, and became the first single South Korean group to play at stadiums in the United States since Big Bang (South Korean band), BIGBANG (Alive Galaxy Tour). The group made a rare live televised performance as a quintet, performing at the "I Am Korea" Gala Concert celebrating 70 years of National Liberation Day of Korea, independence which was broadcast live on Korean Broadcasting System, KBS1. On December 9, 2015, they released the maxi single "A Funny but Sad Day" (웃픈 하루) and the music video was uploaded by CJ E&M in anticipation of their upcoming year-end concerts. Although the group did not promote the song at all, it was the top 30 most downloaded singles that month and remained in the Gaon Digital Chart for six consecutive weeks. They held a series of sold-out concerts in Seoul over five days before heading to Daegu and Busan to celebrate the Christmas holidays and New Year's Day with fans. They took a break in 2016 while the members returned to their solo activities. For the first two months of 2017 g.o.d embarked on their second nationwide tour since reuniting. Entitled ''g.o.d to MEN'' the tour began in Seoul and went to five other major cities. The Incheon concert on January 13 was extended by several hours as it coincided with the 18th anniversary of their debut and culminated in a special fan event hosted by DinDin. On September 19, 2018, jTBC released a trailer of ''Shall We Walk Together'' (같이걸을까), a 10-episode travel variety-reality show which documented the members' trip to walk the Camino de Santiago in Spain. It began airing on October 11, as part of a series of projects to celebrate the 20th anniversary of their debut. On November 27, they released the single "Snowfall" (눈이 내린다) to little fanfare and it debuted at #63 on the Gaon Digital Chart that week with over 9 million downloads and streams despite intense competition from their much younger counterparts. From November 30 to December 2 they held a series of concerts entitled "Greatest" at the Olympic Gymnastics Arena, KSPO Dome before playing in Busan and Daegu on December 22 and 25 respectively. In a positive review, the ''Kukmin Ilbo'' noted that the concerts were appropriately named as g.o.d was one of the few K-pop groups who could put together a full set list consisting almost exclusively of Music programs of South Korea#Chart systems, number 1 songs, with 17 out of 20 songs in the set list being number 1 hits on South Korean music programs. On January 10, 2019, the album ''Then & Now (g.o.d album), Then & Now'' was released. It contains a mixture of new original material, including a title track composed by Park Jin-young, remixed and re-recorded songs from previous albums. On January 13 they held the last of their anniversary concerts, playing to a sold-out crowd at the KSPO Dome. On September 30, 2022, it was announced that g.o.d will hold a year-end concert that will take place at the Olympic Park Gymnastics Stadium in Seoul from December 9 to 11, marking their first performance in four years. On October 14, it was confirmed that g.o.d will be holding an additional Busan concert which will be held on December 24 and 25.

Musical style and themes

Although known primarily for R&B, g.o.d has often displayed their versatility as their albums feature songs which combine elements of different genres such as hip hop, rap, funk and dance pop: their debut single "To Mother" (어머님께) contains elements of hip hop and a refrain sung in R&B style, the upbeat and rhythmic "Friday Night" from the Chapter 2 (g.o.d album), second album heavily features Funk music, funk elements and the ballad "The Story of Our Lives" from the Chapter 8 (g.o.d album), most recent album utilizes a "duet" of the rap and singing parts in the chorus to create a polyphonic texture. Park Joon-hyung has stated that from the beginning he had intended for the group to effectively combine Western and Asian influences into their music. They were one of the few first generation K-pop groups to successfully incorporate elements of African American genres such as rap and hip hop into their music and utilize lines rapped entirely in Korean, which was uncommon at that time. While each song differs in genre, a key characteristic is a prominently distinct and simple melody which is accompanied by a minimalistic piano, guitar or percussion-based Groove (music), groove. Their overall style has been described as a mixture of "belting styles" with "gentle rap, candid lyrics and plain vocal narration". Their ability to seamlessly transition between rap and R&B is apparent in their hit songs, most of which are classified as R&B ballads or pop but contain at least several lines that are rapped. This combination of a prominent lyrical melody and rap has been described as their "signature". Some songs feature a spoken narration to introduce the song. They have shied away from trending genres such as bubblegum pop and electronic music. In contrast to their contemporaries such as

whose repertoire was largely either "feel-good" or hard rock or was choreography-based, g.o.d was focused on lyrical content, garnering them a wider demographic of fans. The trademark features of their repertoire are the "story telling" style and subject matter of their lyrics. MTV Asia describes their songs as "[leaning] towards the social commentary side, with heartfelt lyrics that make people cry until today." Their songs often reflected relatable themes such as love, loss and family or were based on their personal experiences: their debut single "To Mother" was partly based on leader Park Joon-hyung's childhood while "The Story of Five Men" (다섯 남자 이야기) described their frugal living conditions during their first year as struggling young singers. Other songs are more humorous and parodied the members themselves, such as the self-composed "Sky Blue Balloon" (하늘색 풍선), in which rapper Danny Ahn refers to himself by his nickname Skinny Pig. Critics and media have noted the group's unique blend of five distinctly different voices. Mnet (TV channel), Mnet's ''Legends 100'' series noted that "[The] synergy created by these five people began a page of popular music history that has never been seen before."

. As a vocally-focused group, g.o.d did not adopt any image or concept aimed at a particular age demographic unlike most idol groups at that time which were pitched as teen idols and it further added to their "everyman" persona and solidified their nickname "the nation's group". Likewise, they have refrained from colorful and elaborate stage costumes or complex choreography, preferring to utilize themes and simple dance routines to allow members to directly engage with the audience.


Stage

g.o.d is the first K-pop idol group to hold one hundred concerts, a feat they achieved during the "100-day Human Concert" series in 2002 and 2003. They gained popularity and acclaim as consummate entertainers for their stage presence and humorously casual style, often Master of ceremonies, presiding over their concerts themselves. The group is noted within the industry for their interactive approach towards fans during concerts, which often feature segments such as taking song requests or teaching the audience a dance move. Critics have described their concerts as "a giant ''Karaoke box, noraebang''" due to the group's large number of recognizable hit songs. Since their early days, g.o.d's concerts have revolved around specific themes. Their first national tour was entitled "The Story of Five Men", a reference to the eponymous song from their Chapter 2 (g.o.d album), second album chronicling the austere conditions they endured while preparing to debut. The "100-day Human Concert" series notably featured a different theme for each concert. After reuniting in 2014, the group has been more experimental, revising their choreography and the instrumentation of their background tracks several times. Their "g.o.d to MEN" national tour in early 2017 was designed and choreographed as a Broadway musical. Lee Mi-hyun of the ''JoongAng Ilbo'', in reviewing the Seoul leg of the tour, praised the group for their ability to entertain and reinvent themselves without compromising their artistic integrity or losing their unique sound.


Legacy

g.o.d was the first boy band to be dubbed "the nation's group" (), a sobriquet popularized by the media and cultural commentators due to their appeal to not only the teenage demographic, but across a much broader age demographic compared to their contemporaries. In contrast to their contemporaries, who were primarily Teen idol, targeting a teenage audience, they were known as the boy band which "appealed to both teenagers and their parents" and "rose beyond its status as an idol group to be loved by people of all ages." Cultural commentators have noted that the subject matter of their debut song "To Mother" and other songs such as "One Candle" and "Road" further contributed to their broad popular appeal as the country was transitioning out of difficult times and was still recovering from the 1997 Asian financial crisis when the group debuted. They are the first idol group to star in their own reality show, ''g.o.d's Baby Diaries'', beginning a trend of idol singers and other entertainers participating in similar shows such as ''Hello Baby'' and ''The Return of Superman (TV series), The Return of Superman''. g.o.d set a number of records in sales figures. They currently hold the record for the highest-selling album (not including a repackaged version) within a single month – their fourth album ''Chapter 4 (g.o.d album), Chapter 4'' (released in November 2001) sold 1,441,209 copies within a month of its release – and was the only K-pop group to have the sales figures of an album surpass the 1.2 million mark within that time frame until BTS accomplished the same feat in 2017 with the album ''Love Yourself: Her''. They are the most recent K-pop group to sell over a million physical copies of a full album and the last group to do so prior to the establishment of digital music stores, having sold over 1.7 million copies of ''Chapter 4'', before Exo (group), EXO reached the milestone in 2013. The enduring popularity and cross-generational appeal of their songs and their success has influenced many K-pop idol singers of the new generation, such as R&B quartet 2AM (band), 2AM, boy band B1A4, girl group Twice and chart-topping solo artist IU (singer), IU, who have all cited g.o.d as industry "role models" and "inspirations". Widely acknowledged within the Korean music industry as "legends of K-pop", g.o.d is the only guest to perform on ''You Hee-yeol's Sketchbook'' as exclusive guests and the first K-pop group to be the featured legend on ''Immortal Songs: Singing the Legend''. In 2013 the group was selected and featured in ''Legend 100 – Artists'', a Mnet (TV channel), Mnet documentary series highlighting 100 legendary Korean artists (both solo artists and groups) active from 1933 to 2002 selected by a panel of fifty professors, music critics and other music professionals for their contributions and achievements. According to a 2016 poll conducted by ''The Dong-a Ilbo'' in which thirty music industry experts and nearly 2,000 citizens voted for the top 15 greatest male K-pop idol groups of the past twenty years, g.o.d was ranked third by the public and fifth by the panel of experts. Of the inactive or disbanded first-generation groups, g.o.d was the first to make a comeback and still attain success in a highly saturated market in spite of a nearly decade-long hiatus, which commentators have attributed to the overall increased interest in music and games popular during the 1980s and 1990s as well as the fact that the basis of their popularity had been centered on their vocal abilities and the lyrical content of their songs. In contrast to the industry norm for group and all members' individual contracts to be managed by a single company, g.o.d's contractual arrangement was considered groundbreaking for its time as the contracts of the group and each individual member were managed by two different companies. They were managed by and the trademark of their group name is still owned by EBM (now SidusHQ), but individual contracts were managed separately: the individual contracts of the original four members (Park Joon-hyung, Yoon Kye-sang, Danny Ahn and Son Ho-young) were initially managed by SidusHQ while Kim Tae-woo was managed by Park Jin-young's label and agency JYP Entertainment. It would set a precedent in the K-pop industry as this arrangement allowed long-running group
