Entertainment program, produce X 1O1, is on air every Friday from May 3^rd to July 19^th. 101 trainees train in vocals, rap, and dance as they prepare to debut. They practice in Paju English village and they will stay together through their training. They practice for various contests and they are judged by national producers.

Produce X 1O1 operates only on the national producers’ vote. If a trainee gets many votes, the trainee gets a higher ranking. First, the national producer votes for eleven members who want to debut and form a team. A few weeks later, the national producer votes for two members who will be the first and second people to debut. Finally, the national producer votes for the first person to make a debut. On the final day, which decides the team members, the national producer votes through messenger. They send the name of the person who they want to be the first person to debut.

During the program, trainees have to participate in four contests. The first contest is a group battle. All 101 trainees participate in this contest. These trainees cover their senior groups such as BTS, Wanna One, and SVT. The 16 teams cover senior groups songs and dance. The winner of the contest who has the most votes takes the prize. It also influences the next ranking announcement. The next contest is a position contest. The trainees choose the position that they want to do when they debut. This season, there is a new position, which is X position. X position is a collaboration of rap & dance or vocal & dance. They have to do both positions. As it is a difficult task, the reward is double. The trainee who ranks first receives 200,000 votes. The third contest is a concept contest. The national producers choose the concept for the trainee. After the trainees are matched with a song, they have to practice the song and learn its dance. The trainee who ranks first overall receives 500 times his votes plus he receives 100,000 additional votes. The final contest is the debut contest. In the final day of live broadcast, the trainees appear on the stage with their debut contest song.

The trainees’ ranking variation is severe. Nam DoHyon, who ranked 37^th the first week, ranked 4^th the second week. However, Kim YoHan, who ranked 1^st for weeks, ranked 5^th last week. Also, Kim MinKyu, who ranked in the top three for six weeks, ranked 10^th recently.
