I understand Snsd are far more popular but f(x) were doing extremely well too. I found this old post in reddit about girl groups' sales and F(x) was doing really really well for their time.
Yet they don't even got world tour, had first solo concert after 7 years debut (their first and last concert), only get their official fandom name 7 years later too, didn't have official lightstick and the list can goes on. Even F(x) last mv was directed and edited by Amber because Sm refused to do it. I wonder why SM didn't push them more the way they push Snsd. Is it simply because they're not SM priority girl group? I already know kpop since Bigbang debuted but never engaged in kpop community at all during that time. So I wonder what actually happened back then.
I hope smngg will debut with a huge gap from Aespa. If not, this might happen to them or if they turn out doing well more than Aespa, then sm will prioritising them more.
