Infinite Challenge is one of the most popular TV shows in Korea. Although it’s technically only been on the air for four seasons, it has released more than 560 episodes since it began in 2005.
The show itself was a cross between a variety show and a reality TV show. As such, various recurring segments were mixed and matched every week. Although there were hosts, actors, and singers that appeared regularly, a good amount of the segments involved regular people.
Infinite Challenge also occasionally hosted special events. One such event was the 2008 Host-in-Chief Elections, where the entire country tuned in to watch staff from the show vote a new actor in as the host-in-chief.
