Go Youn Jung clinched first place with a staggering brand reputation index of 4,724,038. Her ascendancy to the peak of the rankings is attributed to her high-profile roles in hit series and her rapidly expanding portfolio of premium commercial endorsements.

Hallyu legend So Ji Sub secured the second spot, registering a robust brand reputation index of 4,526,298.

Chronology of the Tracking Period: July 25 to August 25
The brand reputation index is the result of a precise, month-long monitoring window. To understand the rise and fall of these actors, it is necessary to examine the key industry milestones, media events, and releases that occurred between July 25 and August 25.
Late July: The Setup of Summer Blockbusters and OTT Premieres
- July 25–30: The tracking period commenced amid intense summer competition in the South Korean film and streaming markets. Kim Moo Yul’s crime-thriller series No Way Out: The Roulette generated significant pre-release buzz, capturing early search volume. Concurrently, discussions regarding Go Youn Jung’s upcoming dramas and her viral commercial campaigns began building momentum across major online community portals.
Early August: Promotional Surges and Collaborative Announcements
- August 1–10: Media coverage intensified for Jung Hae In as CJ ENM ramped up marketing efforts for I, the Executioner. Press conferences and behind-the-scenes teasers showcasing Jung’s transition into a dark, action-oriented role began circulating widely.
- Meanwhile, promotional material for the project featuring So Ji Sub and Yoon Kyung Ho gained traction, sparking widespread discussion on online forums regarding their chemistry and individual performances.
Mid-August: Drama Premieres and Peak Consumer Interaction
- August 11–20: The premiere of tvN’s Love Next Door on August 17 marked a massive spike in the Participation and Media indexes for Jung Hae In. Audiences eagerly welcomed his return to the rom-com genre, leading to high search engine query volumes.
- During this same window, Go Youn Jung experienced a surge in her Community Index due to high engagement on social media platforms, driven by global fan discussions regarding her acting trajectory and her prominent presence in luxury fashion campaigns.
Late August: Data Consolidation
- August 21–25: The tracking period concluded with the final consolidation of media data, blog posts, café discussions, and social media mentions. The cumulative index revealed that while Jung Hae In and Kim Moo Yul dominated traditional broadcasting and film promotional channels, Go Youn Jung’s exceptionally high digital footprint and consumer interaction metrics pushed her to the top of the overall index.
Supporting Data and Methodology: Decoding the Brand Index
The Korean Business Research Institute utilizes a sophisticated big data algorithm to evaluate the public’s relationship with cultural icons. The brand reputation index is not a simple popularity poll; rather, it is a multi-dimensional metric calculated by aggregating data across four core areas:
┌─────────────────────────────────────────┐
│ Brand Reputation Index Formula │
└────────────────────┬────────────────────┘
│
┌──────────────────┬──────────┴──────────┬──────────────────┐
▼ ▼ ▼ ▼
┌─────────────────┐┌─────────────────┐ ┌─────────────────┐┌─────────────────┐
│ Participation ││ Media │ │ Communication ││ Community │
│ Index ││ Index │ │ Index ││ Index │
└─────────────────┘└─────────────────┘ └─────────────────┘└─────────────────┘- Participation Index: Measures consumer active behavior, such as search volume, website visitations, and direct information consumption regarding the actor.
- Media Index: Analyzes the volume of press coverage, the tone of news articles, and the frequency of broadcast appearances.
- Communication Index: Tracks the organic spread of information, including blog posts, forum discussions, and social media interactions.
- Community Index: Measures social values, consumer sharing, fan club activities, and the overall longevity of public discussions.
For the tracking window of July 25 to August 25, the institute analyzed millions of data points from a pool of 100 actors appearing in current dramas, theatrical films, or OTT content.
Go Youn Jung’s top position was heavily supported by her exceptionally high scores in the Community Index and Communication Index. This indicates that while other actors may have had high media exposure due to active promotional schedules, Go Youn Jung possessed a more active, self-sustaining digital community that regularly shared content, created fan art, and discussed her brand endorsements online.
In contrast, So Ji Sub and Yoon Kyung Ho’s scores were characterized by balanced performance across the Media and Participation indexes, driven by joint press coverage and public curiosity regarding their on-screen partnership.
Official Responses and Industry Insights
The release of the monthly brand reputation rankings is closely monitored by talent agencies, advertising executives, and broadcasting networks alike. Representatives from major agencies note that these rankings have a direct, tangible impact on an actor’s commercial leverage.
An executive from a leading domestic entertainment agency, speaking on the condition of anonymity, explained the industry’s reliance on these metrics:
"Brand reputation indexes are vital tools when we negotiate commercial film (CF) contracts and brand ambassadorships. When an actor like Go Youn Jung ranks first, it validates her appeal to the younger demographic, which is highly prized by cosmetics, fashion, and lifestyle brands. It provides empirical proof to corporate sponsors that investing in this talent will yield high consumer engagement."
Industry critics also point out that the high rankings of Yoon Kyung Ho and Kim Moo Yul indicate a healthy shift in consumer appreciation. Rather than focusing exclusively on traditional lead actors, South Korean audiences are actively searching for and discussing versatile actors who deliver powerful performances in diverse, gritty roles.
This trend suggests that acting merit and project-specific impact are becoming just as influential in driving brand value as conventional celebrity status.
Implications for the Entertainment Industry
The latest brand reputation rankings offer several critical insights into the evolving landscape of South Korean media and global entertainment.
The Power Shift to Multi-Platform Visibility
The top five rankings demonstrate that actors no longer rely solely on terrestrial television networks (KBS, SBS, MBC) to maintain high brand equity. The presence of actors representing OTT platforms (Disney+ and Netflix), cable networks (tvN), and theatrical films highlights the fragmentation of media consumption. To maintain a high brand index, modern Korean actors must successfully navigate a hybrid release model, balancing local television broadcasts with global streaming availability.
The Commercialization of the "New Wave" of Hallyu
Go Youn Jung’s position at the top reflects the successful monetization of the next generation of Hallyu stars. Unlike their predecessors, who built their global fanbases slowly over decades of television syndication, younger actors are achieving international brand recognition rapidly through global streaming algorithms. This accelerated path to stardom allows them to secure lucrative international luxury brand endorsements much earlier in their careers.
The Collaborative Effect in Star Branding
The simultaneous rise of So Ji Sub and Yoon Kyung Ho to the top three highlights the commercial power of "package branding." When co-stars engage in coordinated promotions, they create a synergistic effect that elevates the brand index of both individuals. This strategy is increasingly being utilized by production companies to maximize the promotional reach of upcoming films and dramas, proving that collective marketing campaigns can yield superior results compared to isolated talent promotions.
As the South Korean entertainment industry continues its global expansion, the monthly brand reputation rankings will remain a vital tool for assessing which stars are successfully capturing the public’s attention. With several major film releases and high-budget dramas slated for the coming months, the competition for the top spots is expected to intensify, further driving the creative and commercial evolution of the industry.
