The Korean Wave: From Gangnam Style to Squid Game and K-Pop Demon Hunters5

How South Korean pop culture conquered the West – and why marketers should be paying attention

In 2012, a man in sunglasses and a blue tuxedo galloped across the internet. Gangnam Style by PSY wasn’t just a viral hit; it was the first YouTube video to break a billion views and, arguably, the moment the West realised that Korea could produce global entertainment juggernauts.

But the “K-Wave” – or Hallyu – didn’t stop there. A decade later, Squid Game became the most-watched series in Netflix history, and K-Pop Demon Hunters turned fictional idols into chart-topping real-world stars. What began as a novelty dance has evolved into one of the most powerful cultural exports of the 21st century.

So what’s behind the enduring appeal of Korean pop culture, what might we have inherited from South Korea without realising it, and is K-pop still growing?

Before Squid Game and K-Pop Demon Hunters: The Rise of the K-Wave

The “Korean Wave” (Hallyu) began long before PSY’s horse dance.

In the late 1990s, South Korean TV dramas like Winter Sonata and early pop idols such as BoA and Seo Taiji & Boys started gaining popularity across Asia. By the mid-2000s, Korean entertainment had a strong infrastructure, ready to ride the global streaming revolution.

When Gangnam Style exploded, it wasn’t a fluke. It was the product of a culture that had already learned how to mix high-energy production with mass appeal. Korea’s entertainment industry was built on precision – rigorous training systems, global-minded storytelling, and visual polish that rivalled Hollywood.

Squid Game: When Korean Storytelling Went Global

When Squid Game landed on Netflix in 2021, the world was captivated by a dystopian morality tale disguised as a children’s playground. The series wasn’t just entertainment; it was a critique of capitalist society, inequality and desperation – wrapped in candy-coloured brutality.

What made Squid Game resonate wasn’t simply its shocking visuals, but its universal themes. It proved that language barriers were irrelevant if the storytelling was strong enough.

The result? Over 265 million households tuned in worldwide, cementing South Korea’s role as a global content powerhouse.

For marketers, Squid Game demonstrated the power of emotional storytelling with social relevance – a masterclass in combining local context with global relatability.

What We’ve Inherited from South Korea (Without Realising It)

South Korea’s cultural influence now extends well beyond Netflix and K-pop playlists. Here’s what has quietly integrated into Western culture:

  • K-Beauty and Skincare Rituals – The 10-step skincare routine, sheet masks and “glass skin” trends have become mainstream in Western beauty markets. Korean cosmetic brands taught us that self-care could be ritualistic and aspirational.

  • K-Fashion and Streetwear – Korean designers have shaped global street fashion with oversized silhouettes, neon palettes and sleek minimalism.

  • Food Culture – Korean fried chicken, kimchi, and bibimbap are now staples in high streets and takeaways alike. London’s Pure Seoul stores and Korean BBQ chains owe much to the K-wave’s appetite for authenticity.

  • Fan Culture and Community-Driven Brands – The intense fandom surrounding K-pop has influenced Western marketing strategies. Limited drops, collectable merch, and highly interactive fan events mirror brand engagement techniques used by Apple or Nike.

  • Visual Storytelling – K-pop’s emphasis on choreography, aesthetic perfection and narrative has shaped everything from TikTok trends to brand video production styles.

In short: if you’ve ever queued for a bubble tea, bought a pastel face mask, or used a neon lighting setup for your TikTok, you’re already under the K-influence.

K-Pop Demon Hunters: The Turning Point

If Squid Game showed Korea’s storytelling prowess, K-Pop Demon Hunters showed its mastery of cross-media entertainment. The animated film, which follows a K-pop girl group who moonlight as demon slayers became a global sensation in 2025.

Its fictional single, Golden, hit No. 1 in the UK charts and topped Billboard’s Global 200, making it the first K-pop (real or fictional) song to do so since Gangnam Style.

So why did K-Pop Demon Hunters explode?

  • Hybrid Storytelling – The film fuses anime-style visuals, Korean folklore, and Western superhero tropes, creating something familiar yet fresh.

  • Multi-Platform Experience – Like Squid Game, it exists across formats – film, music, TikTok challenges, and gaming tie-ins – giving fans endless touchpoints.

  • Fan-First Marketing – The promotional campaign used the K-pop fandom model: countdowns, livestreams, character teasers, and merchandise drops that sold out in hours.

  • Cultural Pride with Global Accessibility – While rooted in Korean mythology, it never alienated global viewers. It struck the sweet spot between authenticity and universality.

For marketers, K-Pop Demon Hunters is a blueprint for modern entertainment branding: multi-platform, community-fuelled, and globally inclusive from the start.

Is K-Pop Still Growing?

The short answer: yes, but the market is evolving.

According to the International Federation of the Phonographic Industry (IFPI), South Korea ranks among the top 10 global music markets, with K-pop responsible for a huge share of its export value. Groups like BTS, BLACKPINK and Aespa have sold out arenas in London, Paris and Los Angeles.

Streaming has made K-pop accessible everywhere – you no longer need to understand Korean lyrics to feel the emotional punch. However, critics warn that the genre risks becoming too “manufactured” and globally homogenised, losing the very originality that made it special.

The next chapter of K-pop may rely less on perfection and more on storytelling, individuality and deeper connection – lessons the Western pop industry could do well to revisit.

Why Marketers Should Care

The Korean Wave offers more than catchy choruses and cinematic visuals. It’s a case study in cultural export, brand building, and emotional resonance.

Here’s what marketers can take away:

  • Build community, not just consumers – K-pop fandoms act like self-organising marketing departments.

  • Fuse local authenticity with global accessibility – Korean creators never water down their culture; they amplify it.

  • Invest in aesthetics and storytelling – Every frame, lyric and outfit serves a brand purpose.

  • Diversify content formats – Whether through music, animation, or merchandise, K-pop thrives on cross-platform engagement.

  • Understand emotion as a growth engine – Every successful Korean export hits an emotional chord, from love to outrage to belonging.

TL;DR

  • South Korea’s “K-Wave” has transformed from a niche regional phenomenon into a global cultural force.

  • Squid Game proved Korean storytelling could dominate Western streaming, while K-Pop Demon Hunters blurred the line between fiction, fandom, and reality.

  • Western culture has quietly adopted Korean trends in beauty, food, fashion and fan engagement.

  • K-pop’s popularity continues to grow, but its sustainability will depend on creativity over formula.

  • For marketers, the Korean Wave is a live masterclass in brand storytelling, emotional marketing, and global community building.
