Excluding groups that have disbanded. Including groups that don't renew their contracts with their first company, but not disbanded and still continue activities as a group (Ex: Got7)
Shinhwa (1998~)
SHINee (2008~)
2AM (2008~)
BTS (2013~)
Got7 (2014~)
Mamamoo (2014~)
Seventeen (2015~)
Twice (2015~)
ㄴThey added Yeri to the group. They debuted as a 4-members group at first.
-Got7, Mamamoo, SF9...?
-Block B has never had any member changes too...
-All of KARD's members renew their contract...
-What about Blackpink?
-Basically what you're saying is... Idol groups that never had any member changes from their debut up until their contract renewal...
-There's not a lot of them. Even top idol group like SNSD had a member change. Beast, even though they're popular, also had a member change. So did Oh My Girl, Apink, etc.
-SHINee right after Shinhwa...? I'm sure a lot of idol groups debuted in between them, but I guess maintaining an idol group is not easy after all...
-Should g.o.d be included this post or not...
-That applies to SF9 and Brown Eyed Girls...
-These groups are really amazing. It seems like maintaining an idol group is not easy at all.
-What about 2PM?
ㄴ2PM originally had 7 members...
ㄴJay Park was actually from 2PM...ㅋㅋㅋ
-Davichi
