About half a decade since their debut as a group, seven-member Korean pop act BTS—which they translate as “Beyond the Scene” in English—continues to gain global momentum. They’ve already broken at least one of their own U.S. records in 2018, releasing the highest-charting K-pop album ever (Love Yourself: Tear, which debuted atop the Billboard 200). But the real engine behind their success is their passionate social fanbase, who style themselves as the “ARMY” and eagerly consume anything related to the group, from tweets to videos. For example, the YouTube views within 24 hours for their music video “Fake Love” almost surpassed Taylor Swift’s and Psy’s all-time records—no small feat. The group has notched over 89 weeks atop Billboard’s Social 50 chart, besting Justin Bieber, and recently won Top Social Artist at the Billboard Music Awards for the second year in a row. A steady social media presence for each of the boys—along with periodic solo releases—further bolsters the group, which counts at least 50 million followers across English-language social media platforms. —Raisa Bruner
