Where do all the good shows disapear to from time to time?

I don’t watch TV anymore, but I some times watch shows online. I have noticed that from time to time, a show will suddernly stop for a few weeks, then you get new episodes.

What is going on exactly, I’m not so stupid as to be totally oblivious, I know shows have seasons, and uploading can often be unreliable, but is there a way to predict when it’s going to happen, so I don’t have to keep checking the same 3 sites every day to see if a show is up.

As I live outside of the USA, I don’t have access to guides and such, and most sites simply tell me “your country is on the shit list” if the site has anything to do with American TV.
