As 2012 comes to a close, top social sites are remembering the year that was.
On Twitter, President Barack Obama's "Four more years" tweet became the most popular post of the year—and of the 6-year-old site's history—with more than 760,000 retweets in its first 20 hours.
On Facebook, The Hunger Games earned the most mentions in movies, edging out The Avengers and Magic Mike at No. 2 and No. 3. It also beat out Harry Potter in book discussions. More surprising, though, were the top TV conversation-starters: Here Comes Honey Boo Boo, Game of Thrones, and Downton Abbey were all less popular than ... A&E's Duck Dynasty.
Meanwhile, Google said Whitney Houston was the top-trending search of the year, beating out "Gangnam Style" and Hurricane Sandy. Houston died in February at 48.
