KARA formed in 2007 and despite a lot of success, went through many members changes and eventually disbanded in 2016. Their inactivity left many fans yearning for more KARA, but since 2016, there has been very little news of any sort of reformation. We'd love to see a full-blown KARA comeback in 2019!

Formed by DR music in 2011, Rania debuted with their feelgood track "Dr Feel Good"! This group has been around for close to a decade, but recently came back this year with their Malaysia tour! It was also announced that their former member Yumin is marrying P-Goon of Topp Dogg! Rania has had their up and downs, but despite that have maintained attention and relevancy!

T-ARA debuted in 2009 and gained serious recognition in 2011 with "Roly-Poly". However, early this year, four of the group's members stated that they will not renew contracts with MBK. Because of this, there's a lot of controversy over whether or not the group would disband. To this day, it is unclear whether they've officially disbanded or not, but for now we'll hope the group is just inactive.

It's hard to believe the incredible longevity that Girls' Generation has withstood through the years. The group debuted in 2007 and has had comebacks fairly regularly since. Despite it's hiatus, the group still came back strong and showed that even inactivity doesn't mean a group has fallen off the charts forever! Even with the recent departures of some of the members, we hope Girls' Generation continues to wow us with their talent and charisma.

This talented duo debuted in 2006 under Friday Entertainment, which seems light years away! You may notice that Heo Solji looks familiar- it's because she's now the main singer in EXID! Likewise, Kim Songyi went on to become lead singer of Blady. 2NB reunited with new members in 2016, which is why the group isn't technically disbanded. We'd love to see the new 2NB back in action!

This R&B focused group debuted in 2007 and has since come in and out of cultural relevancy. Unlike it's other counterparts, BEG was able to maintain the same member lineup for 10 years, an almost unheard of feat. Though each member did pursue solo projects, their influence as a group has made an impact on groups and artists like Psy and Girls' Generation.

Probably the oldest group on this list is LPG. LPG debuted in 2005, and three members are currently active as part of the group. LPG has a whopping 16 past members! That's enough to form 4 really amazing groups!

After School is currently comprised of just 4 girls: Raina, Nana, E-Young, and Kaeun. With 7 former members that have 'graduated' from After School, the group still was named one of the Top 10 K-Pop Girl Groups in the Past Decade by Billboard. Though many consider After School disbanded, we're still holding onto hope for a comeback in the near future.

With Sulli leaving the group, the fate of f(x) frightened K-Pop fans across the globe. The group never formally disbanded, but left many uneasy with a hiatus that seemingly has no end. Although we've enjoyed numerous solo projects since their last comeback, we want to see more of this SM powerhouse group by 2019.
