2012: by Youtube

Rewind time... YouTube Style! YouTube made this video with the stars they helped making famous. Some may recognize the videos, but if you don't they have a list on which videos they based to make the parody. There's a video from behind the scenes too :)

2012: by Google

Google has made a tradition on compiling the years' events in a video, a waving goodbye to the ending year. And here it is this years' video. A way to remember the events, the tragedies, the people we lost in 2012. Congrats, Google! Great video!
