But that's not what I said tho - I did not say they were "all marketing," but rather that some shrewd moves were made in marketing them in the West - I've bolded what I said below. Regardless of whether BP had tons of promotion, they had some really smart promotions and marketing in trying to cross over. I don't know why people think it takes away from their group's success to say there were some clever and tactical marketing elements involved. Kpop groups, in particular, are built on a marketing base - a specific look, talents, vibe, aesthetics, elements to address a niche or style in the marketplace, as well as elements that talk to the fan base (whether social media or products). Marketing is not a dirty word, but rather makes the kpop world go round.
Appearing at Coachella was a really big deal and generated much attention and earned media (i.e. people were writing about them for free in news stories). Although they had appeared at Kcon for several years, it was Coachella that generated all the stories. There were also really savvy moves made in the collaborations (fairly mainstream younger artists who are popular with women) vs just grabbing people who appear on anyone's track, like a Pitbull.
I still stick my original point that "Of course it starts with the music and talent and personalities of the women, but I think a lot of smart moves were made for their brand."
