Jennie Effect: How a K-pop Star Boosted Nongshim's Stock
When Jennie from BLACKPINK mentioned the Korean snack 'Banana Kick' on 'The Jennifer Hudson Show,' few expected the market response that followed. The casual endorsement by the K-pop star led to a surge in interest, sending Nongshim’s stock price soaring.
This event highlights the power of K-pop in global marketing and how a single celebrity remark can have economic and cultural ripple effects.

The Meaning and Impact of the 'Jennie Effect'
During the show, Jennie expressed her love for Banana Kick, emphasizing its uniquely sweet banana flavor. This simple mention quickly spread across social media, catching the attention of international consumers.
As a result, Nongshim's stock saw a rapid increase, and global orders for the snack skyrocketed. Social media buzzed with discussions about Banana Kick and Korean snacks in general.
Pros and Cons: Is the 'Jennie Effect' Truly Beneficial?
Pro: A Global Branding Boost
Jennie's mention provided Nongshim with free publicity, equivalent to a multimillion-dollar advertising campaign. This elevated the company’s brand perception and product recognition worldwide.
Additionally, it contributed to promoting the quality of Korean snacks to international consumers, potentially leading to increased exports.
Similar instances have been recorded before—when BTS casually featured certain products in their social media content, those items saw dramatic sales increases. Jennie’s case demonstrates just how influential K-pop stars can be on the global market.
Con: A Temporary Surge and Dependency Risks
Critics argue that the Jennie effect is a short-term phenomenon. Whether Nongshim’s stock can sustain this newfound momentum remains uncertain.
Furthermore, relying too heavily on celebrity endorsements might weaken a brand's identity. If a brand becomes known only because of a celebrity’s influence, consumer interest could fade once the trend passes.
For sustainable growth, companies like Nongshim must focus on product quality and long-term branding strategies rather than relying solely on fleeting star power.
Conclusion and Future Considerations
The Jennie effect is undeniably a positive marketing case study. However, depending exclusively on celebrity influence is not a sustainable business strategy.
Nongshim should seize this opportunity to solidify its global presence while ensuring its products stand strong on their own merit. A well-rounded approach will result in lasting success rather than temporary spikes in popularity.
