Actually in terms of numbers BTS pales compared to 1D, by a lot. At their prime, 1 D held a stadium tour in US, South America, Europe and Australia and played stadiums only in many different cities, not just 3. They sold out Metlife, Rose Bowl and Wembley 3 nights in addition to other other huge stadiums. Backstreet boys are the 18th best selling artists of all time with 300 million records sold. 1D sold 50 million records. BTS is bigger in Asia, especially Japan, which makes sense. Boyband shortlived success is not new, the teenage female market is the most lucrative and easily accessible in the industry. Same with movies/books, remember Twilight? It honestly was one of the most unoririginal poorly written teen love stories, yet all the hype. Retrospectively everyone agrees it sucked. Once the hype dies down, no one will care.
Although with RM throwing in those one eyed handsigns so explicitly at the whole audience in a concert, you never know. Maybe they have higher ambitions. They arent hiding their satanic handsigns in choreagraphy/photoshoots anymore, reminds you of JayZ and his obvious satanic hand signs at every concert. The blind items about JayZ and Beyonce are truly disturbing. If they are allegedly true he deserves the electrical chair, a nasty criminal no doubt. Not only him, but other so called music moguls. Their debauchery knows no end.
