Running Man at 16: Inside Korea's Most Enduring Variety Show

Sixteen years after its debut on SBS, Running Man continues to air every Sunday—a feat that places it among the rarest of television achievements in South Korea. When the show first launched on July 11, 2010, variety television was an intensely competitive landscape with a short shelf life for most formats. That Running Man has reached 2025 still drawing loyal domestic audiences and a global fanbase is less a matter of luck than it is a case study in format resilience and cultural adaptability.

As the show enters its 16th year on air, it occupies a category of one in Korean variety history: no comparable entertainment program has maintained a consistent prime-time slot on a major broadcaster for this duration. Understanding how Running Man got here—and why it matters for the broader Korean television industry—requires looking beyond the surface of the name-tag elimination game that first defined it.

From City Race to Global Format

Running Man launched as a city race show, setting its cast members loose across Seoul to complete missions and eliminate opponents by tearing name tags from their backs. The concept was deceptively simple, but the execution gave it an edge: cast chemistry, competitive stakes, and physical comedy merged in ways that Korean variety television had rarely delivered on a weekly basis. Within two years, the show had exported that format across Asia, with versions appearing in China, Thailand, Vietnam, and the Philippines.

The international reach was not incidental. SBS actively marketed the format, and the cast—anchored by host Yoo Jae-suk, who was already a household name, alongside Kim Jong-kook, Ji Suk-jin, Song Ji-hyo, HaHa, and Lee Kwang-soo—became recognizable faces across the continent. By the mid-2010s, Running Man was arguably the most recognizable Korean variety export worldwide, laying groundwork for the broader soft-power infrastructure that would later propel K-pop and K-drama internationally.

That global foundation proved crucial when the show hit its most serious crisis. Between 2016 and 2017, domestic ratings dropped significantly, cast changes were rumored, and SBS briefly considered cancellation. The international fanbase—numbering in the tens of millions across Southeast Asia alone—pushed back loudly enough that the broadcaster reconsidered. Running Man became one of the first Korean variety shows whose survival was partly determined by overseas viewers, a dynamic that has since become far more common across the industry.

The Architecture of Longevity

Cast turnover is often viewed as a liability in variety television, but Running Man has managed it more gracefully than most. Lee Kwang-soo, beloved as the show's enduring "unlucky" figure, departed in 2021 after 11 years. Jeon So-min exited in 2023. Their replacements—Yang Se-chan and Lee Sang-min—were integrated through extended transition arcs that honored departing members rather than quietly erasing them. This approach to cast management has become part of the show's identity: continuity is treated as something worth preserving rather than disrupting.

The current lineup's average tenure on the show exceeds seven years—a number that would be remarkable in American late-night or panel television, let alone Korean variety, where rotating guests and format refreshes are the norm. That stability provides a relational depth that first-time viewers sometimes mistake for insider exclusivity, but which long-term fans recognize as the show's primary emotional draw.

The ratings picture in 2025 tells a more nuanced story. Running Man averaged approximately 4.6% domestic viewership in early 2025—a figure that, by the standards of peak Korean entertainment television, would once have appeared modest. In context, however, it represents sustained relevance in a fragmented media environment where streaming platforms, short-form content, and dozens of cable channels compete for exactly the audience Running Man was built to serve. Comparable variety programs of similar vintage have long since vanished from the schedule.

Global Reach as a Survival Mechanism

One of the most underanalyzed dimensions of Running Man's longevity is how thoroughly its international audience has cushioned it from domestic volatility. The show is broadcast in more than 100 countries, and its streaming availability on platforms serving Southeast Asia, the Middle East, and beyond means that any given episode reaches audiences far beyond the Sunday night demographic that SBS measures domestically.

This global infrastructure also explains why Running Man commands production investment that pure ratings numbers might not justify. SBS has a commercial interest in maintaining a show that functions as both domestic programming and international intellectual property. A cancelled Running Man is not merely a scheduling decision—it is the retirement of an export that has functioned, across fifteen years, as one of Korean entertainment's most reliable global ambassadors.

International fan conventions, overseas filming specials, and the sheer volume of subtitled content circulating across social media have created a viewer community that operates largely outside the Neilsen Korea measurement that defines domestic success. Running Man's real reach in 2025 is almost certainly larger than any single metric captures.

Impact and the Cast's Role in Cultural Memory

The cast of Running Man occupies an unusual position in Korean popular culture. Yoo Jae-suk, widely regarded as the nation's most trusted MC, has served as the show's anchor across its entire run—his presence lending institutional credibility that newer members benefit from simply by association. Kim Jong-kook's return from military service, Lee Sang-min's emergence as a breakout personality in his own right, and Song Ji-hyo's decade-plus tenure as the program's most consistent female presence have all added chapters to a shared narrative that viewers feel genuinely invested in.

The departures, too, have become part of that narrative. Lee Kwang-soo's final episode in 2021 drew enormous viewership and generated the kind of emotional engagement that variety television rarely achieves. The show treated his exit as a moment of significance rather than a format interruption—and the result was a new form of loyalty from audiences who had watched him grow from an awkward rookie into a genuine fan favorite over eleven years.

What Year 16 Means for Korean Variety

Running Man's continued presence in 2025 is, at some level, an argument about what Korean variety television is capable of building when it commits to longevity. The industry's dominant model favors high-concept seasons and format turnover—launching shows with intense promotional investment, extracting peak ratings, and retiring them before audiences disengage. Running Man has operated on an entirely different logic: relationships built slowly, trust earned over years, and a format elastic enough to absorb cast changes, trend shifts, and platform disruption without losing its core identity.

Whether that model is replicable remains an open question. The conditions that allowed Running Man to survive its 2017 crisis—an unusually loyal international fanbase, an irreplaceable anchor in Yoo Jae-suk, and a broadcaster willing to play the long game—are not easily assembled. What the show's 16th year demonstrates, though, is that the long game can be won. In a landscape defined by short cycles and rapid obsolescence, Running Man remains the clearest proof of concept for sustained variety television in the Korean market.
