Ever wonder how Twitter comes up with their Trending Topics? HP's Social Computing Research Group has the answer.

After analyzing 16.32 million tweets on 3,361 different trending topics from September to October last year, the HP Social Computing Research Group has released the results of their study.

HP discovered that around 31% of trending topics are retweets, and 72% of those came from mainstream media like CNN, NY Times, The Telegraph, ESPN, Breaking News, and Huffington Post.
