YouTube has created a video to 'What Does the Fox Say' to celebrate 2013, featuring a host of YouTube vloggers, viral video makers, TV shows/stars that have been popular on YouTube and musicians. They also did one last year to 'Gangnam Style.' Here's the link if you haven't seen it.
These videos are really well produced like a TV network promo. Made me really reflect on how YouTube has come such a long way since we first logged on to watch LG15 and suspected that it was a production.
