Shifts in K-POP Industry Structure...Teams Rethink Survival Strategies Amid Falling Trainee Numbers and Increased Focus on Content Marketing

The K-POP industry is accelerating its structural transformation away from a focus solely on music and performances toward more diversified content marketing strategies. Meanwhile, the industry faces concurrent structural crises including a sharp decline in the number of trainees, shortened debut cycles for newcomers, and a shrinking domestic consumer base. JYP Entertainment invested 1.12 billion won in nurturing new talent last year, representing a roughly 30% increase from 850 million won in 2023. If the company maintains about 30 trainees, this translates to approximately 3.12 million won invested per trainee per month. Paradoxically, the total number of trainees across the entire K-POP industry is declining rapidly. According to a survey by the Korea Content Agency, the number of trainees stood at 1,170 in 2022, down 725 people (38.3%) from 1,895 in 2020 over just two years. The primary reason for this decline is “rising training costs.” As stated in a graduate thesis titled “Problems and Improvement Strategies in the K-POP Idol Trainee System” (2025), training intensity is so severe that 7 to 8 out of every 10 female trainees experience irregular menstruation, and the voluntary dropout rate has risen from 31% in 2020 to 34.4%. A “class polarization” phenomenon is becoming prominent, with children from wealthy families and second-generation celebrities debuting while ordinary trainees decline rapidly. The survival strategies of K-POP idols have fundamentally changed. Moving away from the once-long comeback cycles and stage-centered activities, factors outside the stage such as SNS challenges, short-form content, and daily branding now determine a team’s competitiveness. HYBE adopted a label-based system to introduce newcomers on shorter intervals, and while music show appearances have been reduced to 1 to 2 weeks, generating buzz on social media has become an essential strategy. IVE’s “Attitude” promotion gained momentum after adding the “Wonyeongtan” choreography, which accumulated 5 billion views in China, while LE SSERAFIM’s “Bokjugiini” section was reinterpreted through fan challenges, attracting additional attention. In the case of KISS OF LIFE’s “Iglu,” even more performances were held than for the title track, illustrating an increasing trend where real-time feedback shapes promotional approaches. The shrinking size of the domestic consumer base is also a factor driving industry restructuring. Some fan bases have migrated en masse to other communities such as baseball, volleyball, musicals, and esports, and the overall decline in the younger population means entertainment companies can no longer rely solely on the domestic market to ensure team growth. As a result, diversified strategies targeting specific audiences have emerged, including virtual idols like PLAVE, HYBE’s global group KATSEYE, and the genderless concept group XLOV. Concerns have arisen amid these changes in K-POP. Critics argue that excessive pursuit of trends dilutes a team’s uniqueness and leads to an oversaturation of similar concepts and production styles. Some critics express worry by stating that “K-POP is eating itself alive” and that “overreliance on public reaction makes it difficult to maintain a team’s original direction.”
