In the older days, KPop Grand Prizes were won by a plethora of acts.
From 2007 to 2012, I remember these acts won Grand Prizes
Epic High
SNSD
But, in the last 4 years, the following acts won Grand Prizes
2018-Jan 2019
Twice
Wanna One (Melon)
Ikon (Melon, Golden Disk)
2019-Jan 2022
BTS
aespa (Melon, 2021)
Fin.
=====
Four acts won Grand Prizes in 2018
Three acts won Grand Prizes in 2019-2021, one of them a relic of the 2nd Generation who significantly had overstayed her welcome
So it got more selective.
In 2019 and 2020 only BTS accepted its Grand Prizes.
And in 2021
only IU accepted her Grand Prizes.
