The entire general public of Korea.
BigBang seems to be the only kpop group that makes people who don't listen to kpop go out of their way to listen to their new comebacks.
The same is not true of BTS. To non kpop fans BTS is just another kpop boy group. Theres really no incentive to search for their comeback if you aren't already their fan.
BigBang exists as something entirely different. They are like an Epik High but on steroids.
BTS represents kpop. But BigBang represents Korea.
