Thank you for commenting. I am not sure which country you live in, but some countries have websites that offer streaming video services for Korean dramas. If not, websites for the various broadcasting companies in Korea (MBC, KBS, SBS) offer videos on their websites but you would have to sign up as a member and some of the content may not be free.
Please let us know if you have any other questions.
As the other commenter said it depends on what country you are in. I am in USA and I watch dramas and movies via : youtube, viki, drama fever, Hulu ( i think they merged with Dramafever for Asian dramas so you will most likely be directed to DF once you click on the video) and Netflix ( which only offers paid subscriptions). I hope this helps.
KissAsia.com features updated (new and older) dramas and movies from the whole of Asia.
YouTube is always a good resource, more so when you know what you're looking for.
OnDemandKorea. com features a wide variety, from dramas, News, Kids, Education, and Variety. Its free, but with ads. Ad free is about $5 a month. Not all content is translated, however, programs with English subs are noted as "En"
One of my favs is kshow123.net. its 100% free features current and past variety shows, its updated reguarly and sometimes the Eng subs are posted there first. But that kinda depends on the show. I've found a few shows not available elsewher on this site.
Joining Amazon Prime (monthly fee) will get you a discounted (about half price) sub to the Drama Fever database.
asianwiki.com is a resource for learning about Kdramas and actors. Theres a great criss reference on actors and the movies they appear in/worked on, as well as info on writers.
