Google releases 2012 YouTube year in review

Every year around this time web sites begin publishing their year-end lists. Top tens in search and social media across every category imaginable. We have seen lists from Google, Yahoo, Twitter and Facebook. Now Google has released its official YouTube top ten trending videos and a retrospective video to accompany the list.

It will come as absolutely no surprise to anyone that Korean pop star Psy topped the list, as his video quickly approaches the magic one billion views mark. The video is not only tops for 2012, but also all time.

The announcement from Google also contains some stunning numbers — over 4 billion hours of video are being watched each month and millions of people are uploading video. Perhaps the most mind-boggling numbers would be storage space and bandwidth, but Google does not release that information.

You can see the top ten most trending videos globally at the link above. If you want to see an individual list for your country then head over to the YouTube Rewind channel. You can check out the video below.
