I usually just jump all over the web. I use google translate freely. I use joovideo ( the name has changed) to preview stuff that has aired. Its all raw but it basically includes every single show that comes out period on a daily basis from korea. On the Chinese side I use love tv. They have a comprehensive list of Japanese, Chinese Taiwanese, Korean and Hong Kong all shows separated by genre and by country that shares a LOT of the airing shows. I go to soompi, I use youtube channels for individual outlets like hunan broadcasting or KBS or JTBC... I have a couple of places to go to watch live streaming television broadcasts. I use cfensi. I have a weibo, twitter, baidu, disqus, instagram account. I visit individual fan sites for actors and actresses. I read chats on the end of shows like in viki or kiss asian. I use MDL a lot :). I have my home page set to asianwiki.com so I can look at all the upcoming shows ( Japan and Korea mostly only there) by month and tv or movie. I am a member of a couple of paid translator sites as well. so i get their research as well as mine on tap. the interwebz are FANTASTIC!!! What made all this possible oddly enough was there was a four day hiatus of shows coming out when a ferry accident occurred in Korea. I had no clue what the heck was going on, no shows at all were broadcasting. It was a horrible time for the Korean nation and I felt deeply sorry for their losses. I finally tried watching the news raw and saw what was wrong, and realized one source is not a good thing.
I almost forgot the most important thing. I have over 15 asian shows outlets ( kissasian, drmafever etc) bookmarked and I also check those daily.
