Album sales increase in general for everyone after 2020 because Kpop becomes more global and the pandemic starts. But before NCT 2020, NeoZone (NCT 127) has 530,000 preorders, then NCT 127’s next album, Sticker has 2.12 million preorders. That’s like 4 times higher. They sell 1.5 million more than their last. NCT dream also goes from 500,000 to 1.7 million preorders from Reload to Hot Sauce.
But if we look at other groups. Txt from Blue Hour to Freeze goes from 400,000 to 700,000 (a 300,000) increase; Stray Kids from Noeasy to this album goes from 830,000 to 1.3 million ( a 500,000 increase); Ateez from Fever p.1 to p.2 to p.3 goes from 250,000 to 350,000 to 810,000 preorders, still not comparable to NCT.
Why does NCT’s album sales jump so much more compared to other groups after 2020 when NCT doesn’t seem a have a bigger hit than the other groups in that time frame?
