K-drama or KD's for short, refers to televised dramas in Korean language, made in South Korea, mostly in a miniseries format, with distinctive features that set it apart from regular Western television series or soap operas. Korean dramas can be set in contemporary times or in historical settings, the Korean word for the latter being sageuk (사극). Different genres apply to these two types, from romantic comedies and action series to fusion science fiction dramas.
South Korea started to broadcast television series in the 1960s, today's mini deurama format of 12–24 episodes started in the 1990s, transforming traditional historical series to this format, as well, creating the notion of "fusion sageuks". Korean dramas are usually shot within a very tight schedule, often a few hours before actual broadcast, screenplays are flexible and may change anytime during production, depending on viewers' feedback, putting actors in a difficult position. Production companies often have financial issues.
Korean dramas are popular worldwide, partially due to the spread of the Korean wave, with streaming services that offer multiple language subtitles. Some of the most famous dramas have been broadcast via traditional television channels, as well, for example Jewel in the Palace (2003) was sold to 91 countries.
