Here is a comprehensive summary of the Wikipedia article about BTS:
BTS (Bangtan Sonyeondan), a seven-member South Korean boy band formed in 2010 and debuting in 2013, quickly evolved from hip hop, co-writing much of their material to address themes like mental health and self-love. By 2017, they led the Korean Wave into the US, becoming the first Korean act to top the Billboard 200 with Love Yourself: Tear (2018) and charting multiple number-one singles like "Dynamite" in 2020, making them the fastest group since The Beatles to earn six US number-one singles. As the best-selling musical act in South Korean history with over 40 million albums sold, their Map of the Soul: 7 (2020) was the country's first to surpass five million sales. Their immense global impact earned them consecutive IFPI Global Recording Artist of the Year awards (2020, 2021), sold-out concerts at Wembley Stadium, and recognition for cultural contributions, including addressing the UN and receiving the South Korean Order of Cultural Merit in 2018. After a temporary hiatus for mandatory military service, beginning with Jin in December 2022, the band confirmed they are working on a new album planned for release in early 2026.
