It shows that every year, the dependence upon the Edam Singer is becoming more prominent in KakaoM , now called Kakao Entertainment's Music Division.
In 2016, Lee Jieun did not promote because she was busy getting her clock cleaned by Park Bogum.'
In 2017 Sistar had its last hurrah.
Ever since 2017, the share of other KakaoM acts decline consistently, and KakaoM's dependence upon KPop's Senior Singer, who now is part of Edam Entertainment owned 40% by Kakao and 60% by Lee Jieun's proxies.
Kakao Entertainment Music Division has PlayM, Starship, Cre.ker and some other labels under it, but the effective owner of Edam Entertianment creates digital shares a few times more than all of them combined.
In other words, in Kakao Entertainment the voice of the Senior Singer overshadows that of virtually everyone else in the company.
I do not know how much influence Lee Jieun has upon the running of other companies, but the current state of KakaoM is that if she says something about artists in other labels, they have to listen to her.
In the history of music, I have never seen a singer being more equal than a single company. Have you?
There is a rumor that Kakao is trying to purchase SM from Sooman Lee. However, if that happens, that means all SM acts will be now overshadowed by the singer who appears to interfere with the management of KakaoM, although she herself appears to be concentrating more on acting than singing now.
