JYP has been know for being the strongest company in the girl group category thanks to debuted some of the biggest and most iconic 2nd and 3rd gen girl groups: Wonder Girls, Miss A and Twice after a huge start each one of those girl groups got affected later on by the company stupid decisions and management and only twice was strong enough to survive those incompetents.
But now in the 4th gen is way worse, Itzy started strong but it was too short they couldn't reach a peak near as half as big as previous girl groups and since the company didn't took the chance to make itzy the top girl group of their gen a huge number of new girl groups debuted, got bigger and overshadow them. Nmixx started really bad, but they have managed to find some little success but they will probably always be a mid tier girl group who can't compete with the high and top tier girl groups. Jyp lost the 4th gen battle so bad it's hard to think about the future of their next girl group in the 5th gen that will debut in 2 or 3 years.
This is sadly all twice fault they become so big and successful that in 2019 when park jin young made another survival show but for staffs called Super Intern every single applicant told him jyp was the twice's entertainment company and that was all they were famous for, jyp didn't like that and after it in company reports it was mentioned making stray kids the pillars of the company was a top priority. 2019 was the year jyp started straight up sabotaging twice career and focusing all their effort in making stray kids bigger neglecting itzy and poorly planning nmixx debut.
