How did Kdramas become so popular?

Korean dramas or Kdramas have been popular for over 2 decades now. However, the rise in popularity shot up during the pandemic. Kdramas were initially watched by people in Southeast Asian countries and in some places in South Asia. When the pandemic hit, a lot of Kdramas were available on Netflix making it easier for people to watch them. With the word of mouth, this soon spread and more and more users were watching Kdramas. Netflix took advantage of this viewership and starting making dramas of their own or buying rights for dramas to be streaming exclusively on Netflix. This soon led to Disney and other platforms making dramas of their own. Kpop has also helped in attracting viewers. Whether it's the captivating story plot, the acting, actors or action, the Hallyu wave has spread throughout the world.
