Because I personally find that to be an unnecessarily restrictive, binary definition of impact. Did you or did you not sell a lot of albums?
I'm not trying to send a stray at Stray Kids (no pun intended), but their Spotify and sales numbers are superb yet nobody would even think of them in a discussion on most impactful group of their era.
It can be part of the conversation but not be the entire conversation.
para 3 - good that's a start but isn't that a subjective measure? one person might say BP influenced them or an idol might say they got into kpop because of BP is that impact? how many idols need to "reference" BP in order to be impactful?
what of fans? Like obviously I'm one person in a million who got into kpop because of BP's D4 and I'm sure lots of others as well - is that impact? vice versa I'm pretty sure lots of people got into kpop because of snsd. I hesitate to make this claim (since kpop has grown massively since snsd's time) but what if I make the argument that more people have gotten into kpop because of BP than snsd - is that impact?
some in the public perceive BP as the biggest kpop GG in the world - there have been comments like Global Girl Group - is that impact? vice versa - snsd were the first??? group considered Nation's GG - is that an example of impact?
furthermore BP is still currently active which means they are still leaving their legacy and building their impact no? SNSD has been around a lot longer than BP has so obviously their impact potential is higher than BPs since they had more time to be impactful (if that makes sense)
Good points. Honestly? There is no real infallible method for answering most of your questions. We would need to run multiple polls and analyze so much data to even come up with a theoretical answer, and even then it wouldn't be conclusive.
That's if you look at how many people became new fans because of a specific group.
Of course, one could easily argue that the newer groups were able to have the opportunity to bring new fans in BECAUSE of the impact of a group like SNSD, who were at the forefront of the Hallyu Wave alongside their peers. There is some give and take there though, for sure.
You can't attribute all of BP's success to their predecessors, but you also have to acknowledge the doors opened by said predecessors. It's a nuanced conversation.
This basically covered your part 4 too.
I personally became a K-Pop fan because of 2NE1 and Big Bang. I have no allegiance to SNSD, andy roots are clearly with YG acts. Yet and still, I feel like SNSD are the most impactful girl group in my time following this industry, and I'd just like to see SOME type of argument to the contrary.
You raised good points though. Thank you for actually engaging the purpose of the thread and not lashing out defensively.
