How will people remember 2011? As the year of Rebecca Black, if the results of Google's Zeitgeist list are to be believed. The momentarily famous "Friday" singer topped Google's annual year-end list of hot search terms, followed by the software giant's own Google+ social network and deceased Jackass star, Ryan Dunn. The top five is rounded out by the acquitted Casey Anthony and the ultra-hot FPS, Battlefield 3. Apple made three appearances in the top ten, courtesy of the iPad 2, the no-show iPhone 5 and its late founder, Steve Jobs. On the other side of the coin, social networks Myspace and hi5 topped the fastest falling lists. Celebrate the year that was with a video after the break.
