Not talking about song quality wise or visual wise or anything like that. I'm talking about girl group public recognition.
Yes girl groups are more popular now than ever before but when you look at the big picture it's mostly just a handful of groups who have all the sales, accolades, and recognition. I'm mostly referring to groups who debuted post 2020. Nmixx, Aespa, IVE, LSF, NewJeans are the only groups who can sell in the millions. Everybody else is barely getting by.
This is identical to 1st gen when you only had S.E.S, Fin K.L., and Baby Vox who could put up decent numbers.
Now compare this to 2nd gen (aka the Golden Age of Girl Groups) you had groups like Girls Generation, Wonder Girls, Kara, 2NE1, f(x), and APink who could sell amazing for their time but even the groups who couldn't sell that much still were well known by the general public and still had hits of their own that everyone knew.
How many girl groups outside of the current five I listed can the average person on the streets of Korea or any country for that matter name? No i'm not talking about you so stop getting ready to type 50 girl groups that you've heard of skimming articles online. People on forums are not casuals. We are the hardcore fans. So of course we can name dozens of groups.
Girl groups had their time. 2nd gen was the golden age and 3rd gen was the last hurrah. Korea's population is declining faster than my patience when I try to listen to a NJ song. And it's getting more and more expensive to debut girl groups with each passing year.
