How 'Hangout with Yoo' Built a Show Bigger Than Its Host

Since July 2019, MBC's Saturday-night staple Hangout with Yoo — sold to international platforms under its literal title, How Do You Play?, before rebranding in 2022 — has run for more than 300 episodes without a fixed cast, a fixed premise, or a fixed name. It remains one of Korea's most-watched Saturday variety shows, a genre of unscripted comedy-and-games programming built around a host and rotating guests.

The host is Yoo Jae-suk, often called Korea's "national MC" for hosting work that has run almost without interruption since the 1990s. What confuses international viewers is that everything around him keeps changing — cast, producers, even the English title. The reason the show survives those changes is structural, not personal.

A relay camera built to replace a legend

Hangout with Yoo exists because of what came before it. Infinite Challenge, the MBC show that made Yoo Jae-suk a household name, ended its regular run in March 2018 after 563 episodes and 13 years on air.

The following year, Yoo reunited with Kim Tae-ho — the producer-director (PD) who had run Infinite Challenge for most of its life — for a looser premise: hand Yoo a video camera on a day with no schedule and film wherever it leads. The show premiered on July 27, 2019, as a "relay camera" format, passed from guest to guest.

Every alter ego gets a beginning, middle, and an end

That loose format hardened into something more deliberate by 2020. Instead of one continuous storyline, the show now runs a series of self-contained "projects," each with its own cast, its own goal, and its own finish line.

A typical project follows the same arc: recruitment or open auditions, weeks of training footage, a collaboration with real musicians or producers, a debut performance, then a wrap. Once one project ends, the next starts from zero.

• Yoo San-seul (2019) — Yoo's trot-singer persona, part of the "Bbong for You" project
• SSAK3 (2020) — a retro co-ed trio with singers Lee Hyori and Rain
• Refund Sisters (2020) — a girl-group spin-off with Uhm Jung-hwa, Jessi, and Hwasa of Mamamoo
• MSG Wannabe and WSG Wannabe (2021–2022) — vocal groups built from open auditions
• JuJu Secret (2023) — a duo that grew out of the WSG Wannabe project

Each of these performed, released music, and disbanded inside the show itself. A viewer can start with any project and lose nothing by skipping the one before it.

The 13-year ensemble the format was built to avoid

Infinite Challenge worked differently. Its six or seven cast members stayed fixed for over a decade, and much of its comedy depended on viewers already knowing years of history between them — a character-driven ensemble format.

Hangout with Yoo reversed that. It launched as effectively a one-man show and added regulars gradually, so no single relationship carries 13 years of continuity a new viewer has to catch up on.

By the numbers, Hangout with Yoo has already out-rated its predecessor: its peak viewership of 13.3% passed Infinite Challenge's 11.1% final-episode rating, according to entertainment outlet Koreaboo.

The show also earned the kind of industry recognition once reserved for Infinite Challenge. Yoo won Best Male Variety Performer for Hangout with Yoo at the 56th Baeksang Arts Awards in 2020, then the ceremony's overall grand prize — a daesang, Korean television's highest individual honor — the following year, according to The Korea Herald.

Why critics say Korea hasn't made a second Infinite Challenge

The gap isn't for lack of trying. Cultural critic Jung Duk-hyun, cited by The Korea Times, argues that the era of "character-driven" shows — where each cast member functioned as a marketable persona — has given way to observational reality formats that put less weight on any one performer.

Content saturation compounds it: with far more shows competing for attention than in 2008, when Infinite Challenge drew nearly 30% of TV viewers, no single program dominates conversation the way it once did.

Hangout with Yoo's project structure works as an adaptation to that environment. It doesn't need one ensemble's accumulated chemistry to carry an entire run, because each project builds and spends its own.

A cast that keeps changing without ending the show

The clearest proof came in 2025. Regular cast members Mijoo and Park Jin-joo left in May, and Lee Yi-kyung departed that November following a personal controversy, leaving the show down to three regulars: Yoo Jae-suk, Haha, and Joo Woo-jae.

Rather than replace them directly, the show ran a recurring segment nicknamed "Insa-mo" (roughly, "gathering of the unpopular"), built around comedian Heo Kyung-hwan's self-deprecating persona. It worked well enough across several specials that producers added his character to the show's own logo artwork.

In March 2026, Heo Kyung-hwan was formally confirmed as the show's fourth fixed cast member, restoring a four-person system, according to SPOTV News. None of this required pausing the show — the cast changed inside the same project format that was already running.

A producer left too, and the format still ran the show

Kim Tae-ho, the creator who designed the relay-camera format with Yoo, left MBC in 2022 after more than two decades at the network. The show did not end with him.

WSG Wannabe launched later that same year, and JuJu Secret debuted in 2023, both under successor producers using the project structure Kim had established. The format had become bigger than any one person attached to it, including its own creator.

Profit and charity built into the format itself

Each music project routes its royalties and merchandise income into donations, a practice that began with Yoo San-seul's trot singles in 2019. In 2020 alone, proceeds from Yoo San-seul, SSAK3, and Refund Sisters totaled roughly 1.8 billion won (about $1.3 million), donated to causes ranging from child-nutrition programs to homeless shelters, according to entertainment outlet Dailian.

The show's commercial success also coincided with a turnaround at MBC itself. After three straight years of operating losses through 2019, the network posted an operating profit in 2020 — a shift executives partly credited to hit variety programs including Hangout with Yoo, according to trade outlet Mediaus.

Ratings still ahead of every Saturday rival

Despite the 2025 cast turnover, the show kept winning its time slot. An October 2025 special tied to MBC's "'80s Seoul Song Festival" broke the show's own yearly ratings record, with a minute-by-minute peak of 10% and a 7.3% household rating in the Seoul metro area — first among all Saturday variety programs, per Star News.

Its rating among viewers aged 20–49, the group advertisers weight most heavily, hit 4.0% that week — first place across all Saturday programming, not variety alone.

What hasn't settled yet

The four-person cast confirmed in March 2026 is only months old, and it is too early to know whether it will hold the way earlier lineups did for years at a time. No new flagship music project on the scale of SSAK3 or WSG Wannabe has been announced since the cast shake-up.

What is verifiable is that the show has now outlasted a full cast turnover, a change of head producer, and direct ratings comparisons to Infinite Challenge — evidence that the project format, not any single person on screen, is what has kept it running for seven years.
