BTS led the Korean Business Research Institute's October 2026 advertising brand-reputation ranking, Thanh Nien reported. The group scored 4,009,253 points, up 1.96% from the previous month, followed by RESCENE and Lim Young Woong. The index uses data collected from September 5 to October 5 and considers participation, media coverage, interaction and community interest. It is an analytical measure produced by the institute, rather than advertising revenue, album sales or a nationwide public-opinion polling percentage.
