As part of the so-called Korean Wave, or the global rise of Korean music, drama and film, BTS has set another milestone not just for their country but to Asian artists around the globe.
Known for their intricately choreographed dance style and good looks, the seven-member group is one of the country's best selling musical exports. The group has been the "underdog" of the Korean music industry not coming from the Big Three groups known as YGE, JYP and SM.
However, it seems their charm and music has earned them fame unlike those from other groups as their return album, Love Yourself: Tear, has topped the Billboard 200 music charts on Sunday based on its sales, downloads and streams of albums.
It had been released earlier in May 2018 as part of their Love Yourself series. In addition, its first single, Fake Love, premiered at the Billboard Music Awards in Las Vegas.
Sung in Korean, the album is "the first primarily foreign-language No. 1 album in over 12 years," according to Billboard.
For the week ending on 24 May, it came in at 135,000 album units, pushing the previous weeks' chart topper Post Malone to number 2.
The band - made up of members RM, Jin, Suga, Jimin, V and Jungkook - has released albums in Korean and Japanese since 2013, and have as much as 10 million followers on social media.
Despite not singing in pure English, BTS have already toured the US and sold out venues in Los Angeles, Chicago and New York.
Their upcoming world tour will take them to the US and Canada before moving on to the UK, Netherlands, Germany and France and some parts in Asia, although the release dates for the rest of the tour is yet to be announced.
All 14 North America dates are already sold out, including the opening four consecutive concerts in the 21,000-capacity Staples Center in Los Angeles.
This is not the only achievement BTS has in their belt. In 2017, their album Love Yourself: Her was the first K-Pop album to crack the top 10 US album charts, rising to number seven.
It also hit the number one spot on iTunes in more than 70 countries.
