Extended information:

Unlimited challenge is MBC TV in South Korea in April 25.

The program was originally one of the links in the variety show Saturday. After many program reforms, it was finally independently presented as the first "real variety show" in Korean TV history on May 6, 26, and was independently produced with different themes and forms every week. The name of Infinite Challenge has been used ever since.

Infinite Challenge has achieved unprecedented success in Korean variety history because of its innovative form, flexible content setting and strong host lineup.

Every episode of Unlimited Challenge is conducted with different themes and forms. The common themes are funny, chase, sports challenge, music performance, TV play, calendar making, personal victory and defeat, environmental protection issues and so on. Korean entertainers and other celebrities are also invited as guests from time to time.

In addition, members once joked that the program was a "3D variety show", where "3D" stands for Dirty, Difficult and Dangerous respectively. The appearance of unlimited challenge program logos, director subtitles and skeletons produced with different themes is also a program feature.
