As of February 2011, YouTube has 490 million unique users worldwide per month, who rack up an estimated 92 billion page views each month. We spend around 2.9 billion hours on YouTube in a month — over 325,000 years (those stats are just for the main YouTube website — they don’t incorporate embedded videos or video watched on mobile devices).
YouTube says that on average there are more than 400 tweets per minute containing a YouTube link. Meanwhile, over on Facebook over 150 years worth of YouTube videos are watched every single day!!!! CRAZY!
Not counting music videos (which due to licensing restrictions are often shown only in the U.S. on YouTube & Justin Beiber wins that with his video “Baby”), the Top 3 most viewed video of all time is the classic “Charlie bit my finger,” with an astounding 282,881,202 (at the time of writing), then it’s “The Sneezing Baby Panda” and “Paul Potts Signs Nessun Dorma”
Now you know!!
