The Stunning Transformation Of BTS

You likely know of BTS even if you're not a big fan of Korean pop music, more commonly known as K-pop. The ultra-popular boy band has taken not just its native country of South Korea by storm, but also the rest of the world, thanks to their catchy music, powerful vocals, lightning-speed rap, and killer dance moves. Even those who don't understand the Korean language have become fans of the band, turning the artists into one of the biggest international sensations in all of music history.

BTS' meteoric rise to fame has not been an accident. The band's formation and record-breaking success have been the product of hard work and talent as well as some skillful planning, strategic publicity, and an army of devoted fans. From their early days as a novice K-pop group to achieving megastar status across the globe, here is a closer look at how BTS has transformed over the years.

While all of the members of BTS are each famous in their own right these days, Kim Nanjoon is arguably the band's most recognizable member. Namjoon is the frontman of BTS and is known by the stage name R.M., which stands for Rap Monster. R.M. both sings and raps for BTS, and he's also a talented songwriter. Namjoon is the only member of the band who speaks English, which, as he told Yahoo! Entertainment, he learned by watching Friends "like a dozen times." The impressive feat was aided by R.M.'s high IQ, reported to be 148, as noted by the South China Morning Post.

R.M.'s skill set would prove to be the foundation of the band that would become BTS. Without him, the group might not have ever existed. Before BTS, R.M. was making a name for himself as an underground battle rapper performing under the stage name Runch Randa as well as performing with Daenamhyup, as noted by Billboard. He became the first member of the group that would become BTS when he was scouted by its founder, Bang Si-Hyuk (via Time).

The band that we now know and love as BTS got its start in 2010, although it would be a while before the artists debuted as a group. A lot of work was put into assembling the right team around its frontman, R.M., after he was discovered by Bang Si-Hyuk that year. "I was ... only 16 years old, a freshman at high school," R.M. told Time. "Bang thought I had potential as a rapper and lyricist, and we went from there."

As Time noted, the rest of the band slowly started to come together. Min Yun-Ki, whose stage name is Suga — it's short for shooting guard — was the second to join the group. Then came Jung Ho-seok, known in the group as J-Hope. The fourth member to join the band that would become known as BTS was Park Ji-min, aka Jimin. Followed by Jimin were Kim Seok-jin (Jin), Kim Tae-hyung (V), and Jean Jeong-guk (Jungkook).

It took a while, but the band that came together was well worth the wait. The members of BTS  became "as close as brothers," as R.M. told Time.

One does not simply become a top boy band star overnight. One of the reasons that it took so long between R.M. getting discovered in 2010 and BTS' official debut in 2013 is that the band had to go through a rigorous training process. The South Korean music industry can be cutthroat, with hopeful entertainers going through grueling training programs in the hopes of making it big.

Vox noted that three major studios began the process of forming "idol groups" in the '90s. They are "polished to perfection, designed to present the very highest standards of beauty, dance, and musicality." Not everyone makes the cut, of course, but those who are chosen for a group are often subjected to a lot of control by the studio, which has a strong hand in not only their music but also their overall image, marketing, and even their personal lives.

Nevertheless, Bang Si-Hiyuk's approach to forming and training BTS in his own studio, Big Hit Entertainment, was a bit more relaxed as he wanted the band to be more authentic. As he told Time, his company's trainees aren't coached solely on performance but also "about life as an artist, including social media."

While BTS is known for its catchy pop tunes today, the band was initially conceived as a hip-hop group. Three of its members, R.M., Suga, and J-Hope, are rappers, as Time noted. While BTS would no doubt have achieved success as a hip-hop group and, in fact, features rap quite prominently in their music, the decision was made to take a route that would bring them to a bigger audience and achieve more commercial success. As Bang Si-Hyuk told The Hollywood Reporter, he wanted to bring rappers and vocalists together to follow "a U.S. pop formula."

This decision wasn't popular with everyone. At the time, Bang was training several performers for the group that became BTS. As he told Time, many of them "wanted to pursue hip-hop and didn't want to be in an idol band." Those trainees left, leaving only R.M., Suga, and J-Hope. The search then began for "members that had more of an idol-like quality." And eventually, Jimin, Jin, V, and Jungkook were added to the lineup.

One of the things that makes BTS so popular with their fans is the fact that their music carries a message with socially conscious lyrics. As noted by Billboard, the band set out to do this with their very first single, "No More Dream," which was released in 2013 when most of the members were still in their teens. The song urges young people not to conform to societal expectations but to follow their dreams. "Dope" is another anthem of empowerment, condemning older generations that look down on the youth. "Am I Wrong" references political issues in South Korea and questions people who are apathetic about the state of the world. Other issues the band sheds light on include bullying and mental illness (via SBS).

Suga told Billboard that the band felt it was necessary to draw attention to such topics. "If we don't talk about these issues, who will?" he asked. "Our parents? Adults? So isn't it up to us?"

It's hard to imagine a time when BTS wasn't the massive international success that it is today, but this boy band was not exactly an overnight success — at least not internationally. BTS released its first single, "No More Dream," ahead of the band's first album, "2 Cool 4 Skool," in June 2013. While BTS' music performed well in South Korea, with Allkpop noting that it made it to No. 5 on the country's Gaon Album Chart, it didn't exactly launch them to international superstar status.

Yet, in the U.S., it was a different story. As The Hollywood Reporter noted, on BTS' first visit to Los Angeles in 2014, the band didn't exactly receive a warm welcome. Instead, they had to walk around the city in order to round up people for a free concert they gave at The Troubadour. And even after all that work, the concert was only attended by a couple of hundred people.

Almost as famous as BTS is their fan club, known as the BTS ARMY. "ARMY" is an acronym that stands for "Adorable Representative M.C. for Youth," as NME has noted. The fan club wasn't organized by fans, but rather by BTS members themselves. They announced the name of their fan club in July 2013, shortly after the release of their first album.

The BTS ARMY is massive and vocal, and its members have been a driving force in the success of the group. The fandom is known for its ardent devotion to BTS. As Michelle Cho, who is a professor at the University of Toronto in its East Asian studies department, told CNN World, "You're not just a casual fan of BTS, you have to be initiated into their world and then you get sucked in."

While many consider themselves a part of the BTS fandom, an official membership in the BTS ARMY costs $30 but comes with perks, such as early access to concert tickets and birthday wishes from the band, according to CNN. There are also rules members have to follow, such as never intentionally boarding the same airplane as BTS.

BTS' social media presence is huge, and it was a major factor in helping them break into the international music scene. The band even holds a Guinness World Record, issued in 2019 for the most Twitter engagements for a music group. 

The band has millions of followers on the social media platform. While this media presence helped BTS break into the international market, their large platforms were also spurred by a "massive guerrilla campaign," as Eshy Gazit, a manager Big Hit Entertainment hired in 2016, told The Hollywood Reporter. Gazit was tasked with helping BTS — who'd recently blown up in South Korea — achieve a similar level of fame in the United States. Gazit said that it was a combo of the band's "inelegant charisma" and timing that helped them become so big in the U.S. "The music industry in the internet day and age is global in every aspect," he said.

Bang Si-Hiyuk also credits fans on social media with helping BTS expand to the U.S., but told Time that the relationship BTS has with their admirers helped cultivate that following. "Loyalty built through direct contact with fans had a lot to do with that," he revealed.

BTS founder Bang Si-Hyuk carefully considered names for the band that eventually became known as BTS. Contenders for the group's name included Big Kids and Young Nation, but Bang eventually settled on BTS, short for "Bangtan Sonyeondan," which roughly translates to "Bulletproof Boy Scouts."

As Bang explained to The Hollywood Reporter, the name symbolizes "the periphery" in which the band exists as members of a young generation fighting against conservative Korean society. Bang said that BTS was formed "at a time of increased longing for fairness and the rights of the marginalized."

As ET noted, the band is also sometimes known as the Bangtan Boys, in reference to the band's full name. In 2017, after BTS reached an international audience, they changed up their name a bit. While they are still officially known as BTS, the letters now stand for "Beyond the Scene."

BTS has changed a lot over the years. As the band's members have matured, its look and sound have likewise shifted. It's been quite the transformation, with fans referring to the various milestones along BTS' transformation as "eras." The Ringer described this as "a blanket term that refers to the entire promotional period of a series of interconnected albums and singles."

As CheatSheet noted, the members of BTS were all in their teens or early 20s when they released their first single in 2013. Their early sound and style reflected their young age, and they frequently sang about teenage problems in what StyleCaster called a "loose school concept." Their music videos were often set in schools and featured the band wearing school uniforms, such as in 2014's "Boy In Luv."

Gradually, the band began to grow into an edgier sound. The 2016 album "Wings" sparked a new BTS era in which the band sang about more adult themes like good versus evil and finding your beliefs. By 2018, the boys of BTS were all grown up and singing about love, both "for yourself and those around you."

While BTS performs primarily in its native language, fans all over the world have become fans of the Korean pop music whether or not they understand the lyrics. BTS has, however, found ways to cater to their English-speaking fans, including collaborating with some of the biggest names elsewhere in the world. As Vox noted, BTS has recorded or performed music with many leading names in the industry — an ever-growing list that includes hitmakers like The Chainsmokers, Steve Aoki, Nicki Minaj, Halsey, and Ed Sheeran.

These collaborations haven't just gotten BTS attention from fans who may have never listened to K-pop, but they've also further endeared the artists to international audiences. The collaborations also seem to have encouraged BTS to branch out a bit. According to NME, BTS' third collaboration with Steve Aoki, 2018's "Waste It on Me," marked the first time that the band sang and rapped a song entirely in English.

By 2017, BTS' position as one of the world's most popular musical groups was official. CNN World noted that the band became the first K-pop group to win a Billboard Music Award. BTS also beat out the likes of Selena Gomez and Ariana Grande. By the end of the year, BTS was ranked on several Billboard charts and had performed on some big stages, including at the American Music Awards, on "The Ellen DeGeneres Show," and on Dick Clark's New Year's Rockin' Eve in New York.

Their success didn't stop there. The Hollywood Reporter noted that the group has been compared to The Beatles "for the hysterical fan mania they generate." BTS also happens to be the first musical group since The Beatles to make it to the top of the Billboard 200 with three different albums in under a year — "a feat that's all the more astounding considering their songs are mostly in Korean," the publication noted. BTS' 2019 tour of the U.S. was so in demand that ticket sales caused Ticketmaster's servers to crash. 

In 2020, the boy band became the first K-pop group to top the Billboard Hot 100 with the English-language song "Dynamite." Not too shabby for a band that once had to scrounge up an audience for a free concert, right?

BTS doesn't just perform songs about social issues — they also back up their beliefs with their money. The band's influence has even inspired others to do the same, such as in June 2020, when they pledged $1 million to the Black Lives Matter movement. As Variety noted, the BTS ARMY quickly followed in their footsteps, vowing to match the group's donation — a feat they accomplished in just 24 hours.

Nicole Santero, a sociology PhD student who researches the culture that has sprung up around the BTS ARMY, told Al Jazeera that there are millions of BTS fans "all over the globe." This makes BTS' social reach huge. While the artists don't often publicly back a particular cause themselves, their fans have been inspired to use their massive internet presence to help others.

An offshoot group, the One in an ARMY fan collective, has volunteers all over the globe who have been helping to raise money for nonprofits since 2018. Causes they have supported include providing Tanzanian families with clean drinking water and emergency relief efforts for bushfires in Australia.

BTS had another busy year in 2022. In May, they traveled to Washington, D.C., and met with then-President Joe Biden to address anti-Asian bullying and hate crimes. A few weeks later, BTS released a compilation album of their greatest hits, "Proof." To the surprise of no one, "Proof" debuted at No. 1 in dozens of countries. Between their performance at the 64th Grammy Awards and their record-breaking Billboard Music Awards win, it appeared for a time as though BTS would never slow down.

On June 14, 2022 — just four days after they released "Proof" — BTS announced that the group was going on hiatus. In the middle of an hourlong FESTA dinner, Suga interrupted a casual conversation to deliver the unexpected news. "We're taking a temporary break now. Should we talk about why we're not doing the FESTA and making content?" Suga said (translated to English via YouTube).

Essentially, BTS decided that they needed a hiatus not only to reestablish the band's future but also to carve out individual paths for themselves. "We have to accept that we've changed ... We achieved this much thanks to our fans, but we aren't living up to their expectations," R.M. explained. "We're trying to find our identity, and that's an exhausting and long process," Jimin added.

Naturally, BTS' hiatus was the talk of Reddit and other social media platforms for quite some time. The general consensus among ARMY netizens was that while they were disappointed by the news, they also understood. "I admire them for knowing what isn't working and taking the steps to address it. It's hard enough to do on a personal level, let alone on the scale of a global superstar group," one Reddit user wrote. Another said, "I'm sad that the group activities will be temporarily halted, but at the same [time], I'm so proud of the boys in taking this step."

When they announced their hiatus during the FESTA dinner, BTS didn't highlight South Korea's mandatory military service as a reason why; at the time, it was still unclear whether they would defer enlistment or not. Plenty of celebrities and royal family members have served in the military, and in the end, BTS became no exception. In December 2022, Jin became the first member of BTS to report for military service; he was an assistant drill instructor. 

J-Hope was the next member to enlist in the military; he began mandatory service in April 2023 and also served as an assistant drill instructor, although he and Jin were not in the same unit. Suga enlisted in September 2023, although because of a previous shoulder injury, he was assigned to public service instead of active military service. R.M. and V enlisted together in December 2023; R.M. joined the military band, while V became a part of the Special Duty Team. Jimin and Jungkook enlisted about a year later: Jimin became a squad leader, while Jungkook worked as a chef. 

BTS have always been an open book, all things considered, so they were quite candid about the highs and lows of serving in the military. As V told Rolling Stone in 2026, "I did really yearn to perform ... since we were needed by our country, we had to do our best with the situation at the time. I tried very hard to forget about V of BTS for a while." R.M., on the other hand, revealed he developed insomnia and once went 78 hours without sleep. "[T]hat experience hitting the rock bottom, psychologically, in truth, I think that helps me ... Now, I'm sleeping on my bed. I'm good," he said (via YouTube).

BTS' hiatus was in full swing in 2023. Although there were no major announcements or new albums to pre-save on Spotify, the group was still a hot topic of conversation. From their individual astrology signs to discussions of how tall BTS really are, ARMY had plenty of material to go through while they waited for crumbs of information. Although they weren't on social media every second of the day, the group still periodically updated their accounts as well, which helped keep up engagement. 

In June 2023, BTS temporarily reunited for the band's 10th anniversary of their debut. That month, they released the song "Take Two." Co-written by R.M. and J-Hope and co-produced by Suga, Big Hit Music accompanied the track with a statement (via NME): "The song conveys their appreciation toward ARMY for all the love you shower them with and their desire to always be together with you. We sincerely express our gratitude to ARMY for making the 10th anniversary possible with your endless love for BTS."

Social media users had a field day with "Take Two," especially on Reddit. As of June 2026, the Bangtan subreddit had over 115,000 subscribers. "Such a great song. The lyrics, their voices, the harmonies and adlibs. Just gorgeous. I'm obsessed with it," one fan gushed. Another wrote, "I cried immediately ... I loved the song and there was something so magical & beautiful about hearing all their voices together again after a long time."

BTS began to branch out as individuals long before they went on hiatus, so by the time they decided to take a break, it was a decision many saw coming. The first member to release a solo project was R.M., who uploaded a free, self-titled mixtape in 2015. The next year, Suga revealed his solo alias, Agust D, with his own free mixtape. By the time BTS temporarily disbanded, all seven members had at least one credit to their name that was unrelated to the band. 

After BTS' hiatus began, solo projects dropped left and right. R.M., Jin, and J-Hope all released their debut solo albums in 2022; Suga (as Agust D), Jimin, V, and Jungkook released their debut albums in 2023; and R.M., Jin, J-Hope, and Jimin released their second respective albums in 2024. Out of all the solo albums that the members of BTS have released through 2026, Jungkook's "Golden" (2023) has arguably been the most successful; it debuted at No. 2 on the Billboard 200. 

Albums aside, the members of BTS enjoyed numerous other solo projects during their hiatus. From tours to promotional events, if a BTS member was available, they were there. J-Hope headlined Lollapalooza Chicago and Lollapalooza Berlin, for instance. Jimin became an ambassador for Dior and Tiffany & Co.; V became an ambassador for Cartier and Celine. As already demonstrated, the list of solo activities could go on.

It took almost three years for all the members of BTS to complete their mandatory military service. Although their military stints were initially supposed to be kept under wraps, that didn't happen in the slightest. BTS' respective discharge dates were widely publicized, complete with tons of pictures from the occasions. Jin was the first to be discharged in June 2024; J-Hope followed that October. V, R.M., Jimin, Jungkook, and Suga were all discharged in June 2025.

On July 1, 2025, BTS finally reunited on camera, a reunion that, at least for a brief moment, seemed to heal the world. The band hosted a 30-minute live session on Weverse, in which they discussed how they were doing, what had changed since fans last saw them together, and how they felt about going solo in the meantime. "It's my fifth day back in Korea ... I'm just really satisfied with my bed," Jimin remarked at the time (translated to English via YouTube). "I wake up at 6:30 a.m. and do morning roll call at home," V added. 

So how did ARMY react to BTS' long-awaited reunion? As one might imagine, social media discussed nothing else for a solid 48 hours — yes, this is hyperbole, but there's also a strong grain of truth to it, too. The flood of YouTube comments wildly varied (and continue to do so over a year later) and were written in all sorts of languages, but they all shared the same sentiment: Everyone was happy to see all seven members of BTS in the same room again. "For the first time in my life, I can't breathe because of happiness," one user wrote on YouTube. 

July 1, 2025, was the cultural reset day for BTS fans. The same day the band reunited on Weverse, they released the following statement: "We'll be releasing a new BTS album in the spring of next year ... Since it will be a group album, it will reflect each member's thoughts and ideas. We're approaching the album with the same mindset we had when we first started (via The Associated Press). BTS also confirmed that they planned to return to tour life, but besides that, no other details were released.

In January 2026, after roughly six months of speculation, Big Hit Music (via Weverse) finally dropped the bomb everyone was anxiously waiting for: BTS' 10th studio album, "Arirang," — referred to as their fifth album by Big Hit because some of their previous albums had a shorter run time — would be available to preorder on January 16. Big Hit's notice included an abundance of information about all the album versions available, including dozens of photos. 

BTS participated in numerous interviews about "Arirang" and what fans should expect from it, and while they didn't provide any specific details about the album, they mentioned their inspiration and goals for the future repeatedly. "Our roots [are] in Korea ... We have to ... come back to where we started from," R.M. said during an appearance on The Tonight Show Starring Jimmy Fallon. When asked what they wanted their legacy to be during an "Actually Me" segment for GQ, Suga replied, "Isn't it a bit early to talk about a legacy? We still have a lot to do" (translated into English via YouTube). "We still haven't made our comeback," Jungkook added. 

"Arirang" (stylized as "ARIRANG") dropped on March 20, 2026; its breakout hit, "Swim," was released as a single the same day. Different members of BTS wrote on various songs, with contributions from musicians like One Republic's Ryan Tedder, Mike WiLL Made-It, Flume, and Diplo. The album was named after the traditional Korean folk song "Arirang." "Every Korean knows it," R.M. explained during the aforementioned Jimmy Fallon interview. "It's by word of mouth ... it includes lots of emotions in it. It could be joy. It could be sorrow, longing, sadness."

From a critical standpoint, most reviews for "Arirang" were positive and scored at the top of their respective rating scales. Rob Sheffield with Rolling Stone rated the album 4.5 out of 5 stars and described the group as "seven different voices, but united again and stronger than ever." Rhian Daly with NME rated "Arirang" 4 out of 5 stars. "After nearly four years, BTS are back doing what they do best — serving as both ambassadors and explorers, fueled by curiosity and creativity," Daly wrote. 

Commercially, "Arirang" overtook the music industry in the blink of an eye. Every single track on the album was featured on Spotify's Top 50 Global chart on its first day, something virtually unheard of. "Arirang" debuted at No. 1 on the Billboard 200, with over 600,000 sales during its first week, and dominated the charts in dozens of other countries, such as South Korea, Italy, Mexico, Japan, and Sweden. In summary, if you didn't hear about "Arirang" in the spring of 2026, one can't help but assume that you lived under a rock.

How many tours have BTS undertaken since their 2013 debut? As a group, five, although if their solo careers are considered, the number rises much higher. BTS has traveled the world since their start. Their first tour, "Red Bullet" (2014 to 2015), took place in North America, South America, Asia, and Australia. Up until the COVID-19 pandemic shutdown global operations in 2020, BTS toured almost nonstop (similar to Taylor Swift, who reportedly makes millions at every concert). Their "Map of the Soul" tour was shelved because of the COVID-19 pandemic, although they perpetuated a semi-online "Permission to Dance" tour in 2021. 

On January 13, 2026 — shortly after the initial, official announcement of "Arirang" — Big Hit Music confirmed on Weverse that BTS would embark on a worldwide tour to promote the album. Currently composed of 88 shows around the globe, the "Arirang" tour kicked off on April 9, 2026, in Goyang, South Korea. BTS is expected to travel across North America, Europe, South America, Australia, and Asia through at least March 2027. 

Interestingly, a Rolling Stone interview published in April 2026 revealed that BTS extended their "Arirang" tour, which was initially just a couple of dates. "When we first got our tour plans, it didn't have very many stops. It was only going to last three to four months," Jin revealed. "Now that we're back, we promised so many people that we would come and meet them, and I feel like [a short tour] is breaking our promise."

While there are a lot people who don't know about BTS, a couple of things have been evident since day one: Their chemistry, talent, and work ethic, both as a group and as individuals, are a force to be reckoned with. When BTS reunited in 2025, they didn't take a leisurely walk back into the swing of things. Instead, they returned to the music scene in any way they could, something that continued to ramp up while on tour.

One of BTS' most prominent appearances after the "Arirang" tour kicked off was at the 52nd American Music Awards. Held on May 25, 2026, the event marked BTS' first time at an award show since the aforementioned 64th Grammy Awards in 2022. The group was nominated for three awards and managed to take them all home: artist of the year, song of the summer, and best male K-pop artist. "ARMYs, we made it once again!" R.M. told the crowd during their artist of the year acceptance speech (via YouTube). 

When they aren't on stage or doing interviews, BTS somehow still has the time to maintain a strong internet presence. Since their early days, the group has maintained frequently updated YouTube channels and X (formerly Twitter) accounts; the members also have individual Instagram accounts that they regularly post on. The most recent BTS livestream, at the time of this writing, was held by Jungkook on June 28, 2026 — one day after the band performed in Madrid.

In November 2022, Jungkook made history when he performed at the FIFA World Cup opening ceremony. Held every four years, the 2022 World Cup skipped its usual summer time slot and moved to the winter because of host country Qatar's brutal heat. Jungkook performed the 2022 FIFA World Cup theme song, "Dreamers," which he co-wrote with songwriter Mustapha El Ouardi and Moroccan producer RedOne. The song reached No. 1 on Billboard's Hot Trending Songs, no doubt, in part, due to Jungkook's popularity. 

For the 2026 FIFA World Cup, officials decided to switch things up to maximize the tournament's entertainment factor (and subsequent viewership): For the first time, global audiences got to experience a dazzling halftime show, à la the Super Bowl. On May 13, 2026, FIFA and Coldplay's Chris Martin — who curated the show's lineup — announced that BTS, Shakira, and Madonna (who has undergone her own stunning transformation over the years) would co-headline the inaugural event on July 19.

With BTS stuck in rehearsals for the FIFA World Cup Halftime Show — again, amid a world tour — the group was unable to watch South Korea play in person before they were knocked out of the competition. They did release a statement through Big Hit Music (via UPI), though: "It will be a great honor to stand on such a meaningful stage where the world comes together. We believe music is a universal language that delivers hope and unity."
