See for yourself why this show is the king of Korean reality television! “Infinite Challenge” is credited as South Korea’s first real variety show and has enjoyed top ratings in its Saturday night timeslot since it began airing in 2005. The mostly unscripted reality program features the hosts and guests tackling challenges that the show’s hosts promise are “3-D”: dirty, dangerous and difficult! The show features popular hosts Yoo Jae Seok, Park Myung Soo, Jung Joon Ha, Haha and Kwanghee. Since comedian Jung Hyun Don’s departure from the show in November 2015, comedian Yang Se Hyung has made regular guest appearances on the show.
