The Korean Wave, or "Hallyu," has spread around the world, and Korean plays, or "K-dramas," have become an important part of culture. During the COVID-19 pandemic, these plays were a popular way for people around the world to pass the time as they could be watched online. This paper looks into how product placement is used in K-dramas as a modern form of advertising. Notably, K-dramas are a great place to put ads for products because they can help people recognise brands, get interested in them, and buy things. This study is based on literature review to try to figure out how product placement in Korean dramas is used in real life. By doing this, it hopes to add to our understanding of how advertising and customer engagement are changing in the digital age.
