Yoo Jae-suk
Yoo Jae-suk (유재석) has spent more than two decades setting the pace for Korean variety TV, turning quick reads, deadpan timing, and audience trust into one of the most durable careers in the business. Since his 1991 debut, he has anchored era-defining shows including KBS's Happy Together, MBC's Infinite Challenge, SBS's Running Man, and Hangout with Yoo. That range is why he still feels central instead of legacy. In 2026, KBS tapped him to lead Happy Together: Glad Not to Be Alone, a team-based music storytelling reboot that leans on the same warmth and control that made the original franchise stick. Yoo remains the rare host whose name alone can make a network reboot feel credible.

Why is Yoo Jae-suk called the Nation's MC?
Yoo Jae-suk earned the nickname because he has led multiple generation-defining Korean variety shows, including Happy Together, Infinite Challenge, Running Man, and Hangout with Yoo. His reputation comes from consistency as much as popularity. Networks trust him to carry flagship formats, and viewers across age groups still see him as Korean TV's safest pair of hands.
What agency is Yoo Jae-suk signed to?
Yoo Jae-suk is signed to Antenna, the Kakao Entertainment-backed agency he joined in 2021. The move was notable because Antenna had been known mainly for musicians and producers before adding Korea's biggest TV host to its roster. He also became one of the company's major shareholders.
What shows is Yoo Jae-suk best known for?
His signature titles include Happy Together, Infinite Challenge, Running Man, and Hangout with Yoo. Each show hit a different phase of Korean entertainment, from late-night talk to large-scale mission variety and format-driven project programming. That breadth is a big reason Yoo remains relevant well into the streaming era.
Is Yoo Jae-suk returning to Happy Together?
Yes. KBS confirmed Yoo Jae-suk as the main MC for Happy Together: Glad Not to Be Alone, a 2026 reboot that reworks the old franchise into a team-based music storytelling audition. His return is the key reason the revival is being treated as a major entertainment event instead of a routine nostalgia play.
