An idol (Korean: 아이돌; RR: aidol) is a type of entertainer who works in the field of Korean popular music (K-pop), either as a member of a group or as a solo act. They typically work for an entertainment agency that operates a highly managed star system that idols are produced by and debut under. Idols undergo extensive training in dance, vocal performance, and foreign language, and tend to represent a hybridized convergence of visuals, music, and fashion. Idols maintain a carefully curated public image and social media presence, and dedicate significant time and resources to building relationships with fans through concerts and meetups.
