Korean dramas, more popularly known as K-Drama, are television series in the Korean language that are made in South Korea. They are popular worldwide, especially in Asia, partially due to the spread of Korean popular culture (the "Korean Wave") and their widespread availability via streaming services, which often offer subtitles in multiple languages. Many K-dramas have been translated internationally, and some of them have had a significant influence in other nations. In other countries, traditional television channels have broadcast some of the most well-known dramas.
Actors and actresses: In the 2000s, it became customary to cast popular K-pop idols in dramas. Initially, this generated mixed reactions. Their appearance had provoked predominantly negative reactions outside their fandom because singers and dancers acting outside of their musical circle was regarded as unprofessional. Also, some idols were criticized for poor acting. Nowadays, this has become much more common feature in Korean dramas, as the public has been getting more used to the concept of "idol actors" and some idols have become known for their excellent acting skills. Their critical reception is still mixed, however, some of them, like Bae Suzy, IU, Yim Si-wan, Seo In-guk, Ok Taec-yeon, Park Jin-young, Doh Kyung-soo and Im Yoon-ah, became successful as actors and actresses.
