Hailing from South Korea, BTS is now the biggest boy band in the world, topping charts and setting records as they continue on their current world tour. Since their debut in 2013, the seven member group — which consists of RM, Jin, Suga, J-Hope, Jimin, V and Jung Kook — have grown beyond the bounds of traditional K-pop acts, making a splash everywhere from Chile to California. Their devoted followers, styled as “ARMY,” have kept them trending on social media at most public appearances, while their musical releases, like this summer’s “Idol,” have broken records on YouTube and international and domestic charts.
