How do anime, K-drama, and live-action adaptations influence the popularity and sales of their source manga, manhwa, or comics?

Adaptations serve as powerful marketing tools, often leading to a massive increase in the popularity and sales of the original source material. Anime adaptations of manga (e.g., *Demon Slayer*) can cause explosive spikes in manga volume sales, drawing new audiences to the printed work. Similarly, successful Korean dramas based on manhwa/webtoons (e.g., *True Beauty*) introduce the webtoon to millions of viewers who then seek out the original. Hollywood blockbuster films and TV series based on Western comics (e.g., the Marvel Cinematic Universe) introduce characters and storylines to a global audience, significantly boosting comic book sales and cultural relevance, turning niche properties into mainstream phenomena.
