Muhan Dojeon (Korean: 무한도전, Hanja: 無限挑戰) is a Korean television entertainment program, distributed by MBC. As of August, 2007, it had the largest market share for its timeslot, with between twenty and twenty-five percent of Korean television viewers watching Muhan Dojeon at 6:40 PM. This makes it the top free-to-air television program on Saturday evening, and also the 1st position of non-drama programmes in Korea every week (except special sporting events, since November 2006). It has kept the same scheduled time since first airing in 2005. It runs for 70 minutes, including ten minutes of advertising. Episodes are also frequently rerun on several Korean cable broadcasting channels.
