'Beyond Asia, onto the world': How BIGBANG pioneered the K-pop world tour [BIGBANG 20th anniversary ③]

"An effect on par with the World Cup."

That is the phrase foreign media outlets have rushed to attach to the economic impact K-pop groups generate on world tours. K-pop has now entered what can only be called the age of the tour — and tracing the origins of that era leads directly to BIGBANG.

Lee Gyu-tag, a professor and director of the Global K-Center at George Mason University Korea, called BIGBANG "the group that most properly established the concept of a world tour for K-pop idols."

In the past, K-pop's reach was concentrated in East Asia. Beyond that region, groups rarely ventured further than a handful of cities in the United States and elsewhere, and even those shows were often aimed at Korean diaspora communities. Lee said the economics simply did not work. "Because world tours were not financially viable, it was impossible to stage large-scale shows across multiple regions," he said.

BIGBANG fired the opening shot for global touring when they became the first Asian act to win the Worldwide Act award at the 2011 MTV Europe Music Awards in Belfast, United Kingdom, and then broke new ground in 2012 when their fifth mini-album "Alive" became the first Korean-language album to chart on the Billboard 200, entering at No. 150. The touring era began at the same time: their 2012–2013 Alive Galaxy Tour took them to 25 cities across 16 countries, where they performed for about 800,000 fans.

Lee said BIGBANG was "the first group to establish in K-pop the concept of a true world tour — not a diaspora-focused event, but a full continental circuit aimed at local fans around the globe." He added that the global concert infrastructure BIGBANG boldly pioneered made it possible for BTS and BLACKPINK to mount large-scale stadium tours more quickly and reliably. In his analysis, BIGBANG was the trailblazer that paved the road wide and flat so that the groups that followed could walk it.

As the world tours continued, BIGBANG proved themselves the highest-drawing K-pop group in global concert history. Their 2015–2016 BIGBANG MADE World Tour spanned 66 shows across 32 cities in 15 countries, drawing a total of 1.5 million fans — the largest single tour in K-pop history at the time.

In Japan particularly, BIGBANG became the first overseas act to stage a five-dome tour — taking in Tokyo Dome, Kyocera Dome Osaka, Fukuoka PayPay Dome, Nagoya Dome and Sapporo Dome — for five consecutive years from 2013 to 2017, a feat even top-tier Japanese artists struggle to achieve. The run drew a cumulative audience of about 4.2 million. Their total solo concert attendance worldwide has surpassed 8 million. The industry widely regards this as the pivotal moment that shifted K-pop's overseas business model from album sales to live business — consistently filling major stadiums around the world.

BIGBANG's 20 years have not always been smooth. The group weathered legal troubles involving members, departures — Seungri and T.O.P left — a long hiatus during mandatory military service, and a restructuring of the lineup. Even so, the explosive success of their 2022 digital single "Spring Summer Fall Winter (Still Life)" as a four-member act demonstrated strong brand resilience.

BIGBANG's 20th-anniversary chapter stands as proof of K-pop group longevity — shattering the long-held industry assumption that an idol act's lifespan is short.

Pop music critic Lim Hee-yun said BIGBANG had broken free from the one-off reunion model that defined first-generation idol groups after their brief peak. "BIGBANG, and many groups that came after them, have moved toward more sustained reunions," he said. Lim also noted that K-pop today, buoyed by an expanding fan base, has come to occupy a place similar to pop genres where listeners dig deep into back catalogs. "BIGBANG is the standard-bearer of that shift," he said. "They are the common ancestor of many groups active today, and they have become an essential reference point when a new generation learns the lineage of K-pop."

Now operating as a trio — G-Dragon, Taeyang and Daesung — BIGBANG released a new single, "BiiiG," to mark their 20th debut anniversary and launch a major stadium world tour beginning Friday. The grand 20th-anniversary festival, which the group had been building toward since last year, is finally getting underway.

Critic Kim Do-heon drew a parallel with veteran foreign rock bands. "Just as seasoned rock bands go on tour to give longtime fans a great time, BIGBANG is creating a festival atmosphere where they connect with fans rather than trying to prove themselves through new music," he said. "They channel the hunger for new material through their well-established solo careers, and on the full-group stage they show the way forward — enjoying the moment with audiences through their catalog of proven mega-hits." He added: "In a K-pop scene that constantly demands youth and flawless beauty, BIGBANG has shown the most exemplary way to age with grace as veterans."

Lee also said that unlike first-generation groups that limit themselves to occasional one-off performances, BIGBANG's members have each consistently built their capabilities as solo artists and are now channeling that accumulated strength back into the group as synergy. "Grounded in the creative ability to write their own music, they have presented a model blueprint for a long-running K-pop group that can endure well beyond its 20th anniversary," he said.
