What You Watched and Searched for on YouTube in 2009

This year has been the biggest yet for online video, and for the first time we're sharing our official Most Watched lists and some of the fastest-rising search terms on YouTube. Some moments were big (President Obama's inauguration), some small (a Minnesota wedding party erupts into dance), some expected ("N ...ew Moon"), some surprising (Susan Boyle) — but all of them inspired, entertained and connected millions of people around the world via YouTube.
