BTS Makes History: 18.4 Million Viewers Tune in for ‘ARIRANG’ Concert - What Does This Mean for K-Culture?

BTS released their fifth full-length album, Arirang, on the 20th and staged BTS Comeback Live: ARIRANG at Gwanghwamun Square on the 21st. Netflix reported on the 25th that 18.4 million viewers watched the performance that day.

The concert film hit No. 1 on weekly charts in 24 countries and regions and broke into the Top 10 in 80 markets. Those placements were achieved with just two days of viewing data, underscoring the scale of the response.

Online reaction was immediate and massive. Netflix said there were roughly 2.62 billion social mentions related to BTS around the event — more than double the previous Netflix live-project record of 1.25 billion — a clear indicator of the fandom’s global mobilization.

The comeback also sparked renewed interest in Korean culture. A social analysis found that English-language mentions of landmarks and cultural terms — including Gyeongbokgung, Sungnyemun, gugak (traditional Korean music), the Bell of King Seongdeok and King Sejong — surged between the 17th and the 23rd, with roughly 80–90% of those mentions clustered around the comeback period.

Mentions of King Sejong, in particular, jumped about 630% on the 21st compared with the previous day, a spike analysts attribute to the Gwanghwamun Square performance. Other Korea-related keywords, such as the Bell of King Seongdeok and independence leader Kim Koo, also drew concentrated attention over a short period.

Meanwhile, BTS hosted the Spotify X BTS: SWIMSIDE event on the 24th and are slated to appear on NBC’s The Tonight Show Starring Jimmy Fallon on the 26th and 27th.
