Infinite Challenge (a.k.a. Muhan Dojeon) is a Korean television entertainment program, distributed and syndicated by MBC. Infinite Challenge is recognized as the first "Real-Variety" show in Korean television history. The program is largely unscripted and follows a similar format of challenge-based Reality Television programs familiar to Western audiences. The challenges are often silly, absurd, or impossible to achieve, so the program takes on the aspect of a satirical comedy variety show rather than a more standard reality or contest program. Infinite Challenge has been called the nation's variety program, and Korea's first real variety program, for having been successful for over a decade.
