Product Placement (PPL) in movies has established itself as a marketing strategy that goes beyond mere product exposure, combining storytelling with brand image.

1. History of PPL
- Early Days : From the early days of cinema, product exposure existed, but it was primarily at a level of appearing naturally as background or props.
- Commercial Film Era : After the 1980s, as commercial films developed, PPL began to be utilized more actively. This was a natural progression as film production costs increased and sponsorship became important.
- Digital Age Expansion : With advancements in digital technology, PPL has become more sophisticated. It is utilized in various ways, such as naturally integrating products using CG or having movie characters mention specific brands.

2. Recent PPL Trends
- Natural Integration : Rather than awkwardly exposing products as in the past, PPL is evolving to blend more naturally into the movie's story and characters.
- Combining with Experiential Marketing : Trends are moving towards combining PPL with experiential marketing, encouraging audiences to want to experience the products themselves.
- Linking with Influencer Marketing : Utilizing influencer characters in movies to promote products and maximizing marketing effects through collaborations with actual influencers.
- Utilizing New Technologies : New technologies like VR and AR are being used to provide audiences with more immersive experiences and enable interaction with products.
- Emphasizing Sustainability : With increasing concern for environmental protection and social responsibility, there are more cases where PPL focuses on sustainable products.

3. Advantages and Disadvantages of PPL

Conclusion
