MBC's headline variety program 'Infinity Challenge' is on the cusp of reaching 400 episodes since it debuted in 2005! With the anniversary approaching, speculation has begun on what the show's big episode will be like.

"We're deciding between just doing a small-scale episode or creating a special broadcast," said chief producer Jun Jin Soo. "Whatever will do, we'll do it with the trademark 'Infinity Challenge' flair."

"As you know, all of our episodes are special episodes," he said. "Because of that, it's hard to come up with items. It's very difficult to take in the opinions of both producers and the viewers to come up with new ideas."
