Yea, but there was still a lot more variation and the variation was more noticeable and easier to distinguish, because there wasn’t nearly as many groups debuting a year. Now almost every week someone new is debuting. It’s overwhelming and it becomes harder to pin point unique enough differences to choose a star. Same issue with 4th Gen boy groups.
Yeas of course that in the 4th Generation more Groups debut because the Kpop industry are growing and growing so everyone want a bit of the cake. And sure that there was more variation in the other Kpop Generation because there was more concept that was never try before but in the 4th Generation nearly every concept is already done by one or two groups.
Sure that that a lot of group are similar and because of the mass of group they all blend in but it also was like in the 3rd Generation.
I mean I don't know how many group debut but we a know that there where a lot if groups that debut in the 3rd Generation and really only a Handful of groups really stand out.
And this will also happen in the 4th Generation there be will be groups that standout of the mass. And these group will represent the 4th Generation.
