Produce X 101 Episode 1

The trainees from each company enter the studio, where seats are arranged numbered from 1 to 101. Each contestant chooses his preferred seat before being informed about several changes that will be applied in this season. Then contestants perform in a group or individually according to their company for evaluation. Some participants are asked to showcase their skills for individual evaluation. Each trainee is judged on his potential and judges grade and assigned them into temporary groups for training: A, B, C, D, and X (with A being the highest and X the lowest). At the end, the popularity ranking is shown with Jellyfish Entertainment's Kim Mingyu taking 1st place. (Source: Wikipedia)
