There are many reasons why Korean TV dramas only release two episodes a week. Here are some possible reasons: 1. Production cycle: The production cycle of Korean TV series was usually long and required a lot of time and energy. In order to balance the production progress and audience demand, Korean TV dramas could only release two episodes per week. 2. Market strategy: The Korean TV drama market is highly competitive. In order to attract more viewers and maintain the topic, the producers may need to launch more dramas in a limited time to establish a wider influence among the audience. 3. Audience requirements: Korean TV viewers usually like to watch continuously instead of skipping. Therefore, if they could only release two episodes per week, the producers might need to maintain enough plot continuity in each episode so that the audience could better immerse themselves in the story. It was a production and marketing strategy for Korean TV series to only release two episodes a week to better meet the needs of the audience while maintaining production progress and topics.
