As in members can leave their girl group's label but still comeback as a whole?
To start, I'd like to mention that Brown Eyed Girls (BEG) have also made a comeback while the members were in different labels, and before SNSD. But I think that the scale of SNSD's comeback makes it more significant.
And this discussion isn't just for girl groups that are disbanded or on indefinite hiatus, it's also about current top girl groups such as BLACKPINK and TWICE whose members will likely not stay in their original label forever.
Of course we don't fully know if this comeback was the result of sheer effort from the members to push their respective labels to cooperate, or it was an act of kindness from SM to allow SNSD to become their first group to comeback even if many members aren't with the company, but the result is the same: SNSD has shown that girl group members don't all need to be part of the same label to produce a comeback.
Will that mean that other entertainment companies will now be open to sharing profits for a veteran group to comeback? Let's say Wonder Girls want to have a reunion, will JYP allow it? Or say some members of a group you stan "leaves the company but not the group" (cliché), there's now hope that they can be part of a future comeback?
Or maybe this is just an exception, and there's very little chance that members that are in different labels than the original one will make a comeback, and if all of them leave the original company it means the group is essentially disbanded?
Discuss (boy group stans welcome too)
