I have been a long-time Netflix subscriber and even though I give Netflix credit for introducing me to the wonderful world of Korean drama, I am a loyal Viki viewer. I became a loyal Viki viewer because Netflix didn't have enough TV series and movies to satisfy my appetite. These days, Netflix has added lots of K-dramas to their database. However, Viki has more Korean historical period dramas which I am addicted to. Also, I like the Viki Original Series better than the Netflix Original Series. By the way, Tubi also has a selection of Korean dramas.
