As you know, one of the ways for Kpop groups to become really popular is to promote in other avenues aside from music. It's how Kpop lures us all in for the long haul. However, Yang Hyun Suk has found an ingenious way to promote his new group.
In the new generation of girl groups, the ones at the top are Twice, GFriend, Red Velvet and now Black Pink. In the second tier, there's Lovelyz (which is a shame tbh lbr since they are the most consistent group) and Oh My Girl. The third tier is populated by a lot of groups that have the chance to shine because of certain members or the success of groups in their parent company.
You'll see many of these groups have their members MCing music shows, appearing on variety shows, bombarding us with CFs, holding V-Lives, branching out into acting, etc. For example, Twice is everywhere and is undoubtedly this generation's girl group to beat. GFriend has been sweeping the music shows this year and the members are increasingly appearing on various variety shows. With Red Velvet, Irene is carrying the group on her back at the moment, but Joy has been in WGM and Yeri has MCed.
Where does this leave Black Pink? Fucking nowhere. They have no schedules except to collect trophies on Inkigayo because of course Inkigayo gives trophies to YG artists just because. However, Black Pink still has to have good sales and a fan base to win on Inkigayo, so how does Yang Hyun Suk do it?
1. Deprive VIPs and Blackjacks of music from their favorite groups
The easiest way for YG to do anything is to build up the image of the "YG Family". Unfortunately, there are a lot of Kpop fans who like YG groups because they act black. Bobby has the hip-hop culture down with his prohibition on showering and GD and Bom love drugs. That's not to say all black people don't know what soap is and use marijuana to bathe (or if any at all, but people will now blame me for creating this new image).
Since the majority of YG artists have the "urban/hip-hop/R&B/yoloswag bullshit" cornered in the idol game, fans of one YG group will naturally gravitate towards another YG group. So, in step one, deprive the two main groups' fans of any music for years.
2. Hype the debut of your new girl group for years and years and years
Was it 2012 or 2013 when YG started hyping up the new girl group? I don't remember, but I remember that it was a long-ass time ago. When fans are anticipating a new girl group for years, in combination with 2NE1 not doing anything aside from CL having God-awful songs in the U.S., YG fans will be thirstier for a song from a girl group than I would be if it was announced that a Han Ye Seul x Victoria lesbian porno would be released.
3. Take advantage of the idiocy of YG fans
I shouldn't have to explain this after five years of doing it.
This is how Black Pink has been so successful already. Once they move on from having Teddy producing "music" for them will they have a shot of making me a fan (the girls are hot, unlike 2NE1, so they're 50% of the way to making me a fan, but I cannot get on board with more yoloswag bullshit from YG).
