Best selling girlgroup album sales throughout the years

I found this tweet while searching for something else:

I looked up the figures for each album (wiki and, when available, Gaon. I couldn't find the hanteo figures):

2007 SNSD #GG => 206,000
2008 WG #TWY => 73,914
2009 SNSD #Genie => 200,000
2010 SNSD #Oh => 418,000
2011 SNSD #TheBoys => 464,000 (Gaon 2011: 385,348)
2012 SNSD-TTS #Twinkle => 155,521 (Gaon '12: 144,222)
2013 SNSD #IGAB => 308,000 (Gaon '13: 293,302)
2014 SNSD #MrMr => 165,400 (Gaon '14: 163,209)
2015 SNSD #LH => 155.000 (Gaon '15: 145.044)
2016 TWICE #TCL1 => 491,670 (Gaon '16: 350,852)
2017 TWICE #Signal => 397,781 (Gaon '17: 285,294)
2018 BLACKPINK #SU => 379,302 (Gaon '18: 230,656)
2019 BLACKPINK #KTL => 463,466 (Gaon '19: 324,577)
2020 BLACKPINK #TA => 1,369,586 (Gaon '20: 1,244,802)

It's kinda amazing how, even when streaming has grown to become the norm over the years, sales of physical albums in K-pop has increased to such extent that they can compete with best-selling American artists

Is this list Hanteo only?

Quote from Serendipity2000

Is this just hanteo?

The tweet says [hanteo], so I assume it's hanteo.

I was kinda surprised, I looked but couldn't find an official hanteo sales site, like there exists for Gaon (if anyone has a link to such an official site, feel free to share and post).

Damn the fact that SNSD got the best selling Kpop album for 7 years

and got the best GG album the year of their debut is impressive

a lot of people are acting like SNSD got big in 2009 with Gee

but you can see that they were already big before gee

SNSD were already the #2 girl group as soon as the year they debuted.

It's just that their fame and success exploded to extraordinary, unequaled heights with Gee and the comebacks and other activities that followed: they were active, present in variety shows and wellknown to the public already, but from 2009 onwards they were everywhere.

i gonna be forever mad that YG didnt push 2ne1 enough during their prime

They could've at least had one or two years as the top if YG wasnt so focused on BGs

I think from 2009-2011 they got great push, but then things started to slow down in the typical YG way.

Their other groups and solo artists also suffered from these long hiatuses and dungeon imprisonments, but due to them 2NE1 started losing the momentum that had been building until 2011 and IATB.
