Yahoo! Movies has listed the top 10 most streamed trailers from their site in the past year.  They're all blockbuster movies except for one.  You'll know which one it is and after you see the trailer, you should know that the movie is available on Netflix "Watch Instantly" and you should add it to your queue.

But since it's mostly blockbuster movies, there aren't a lot of surprises.  Of course, sometimes Yahoo! Movies gets an exclusive trailer and sometimes Apple.com gets it.  Since they're tracking video streaming numbers, their list may not match Apple's (if Apple ever released a list, which I doubt they will).  Also, keep in mind that this isn't a list of the year's best trailer, just the ones that got the most hits.  If you want a countdown of the best trailers, come back later today when I'll list my top five.

Hit the jump to check out all ten of the year's most-watched trailers.
