Top 10 YouTube Videos of All Time

YouTube has come to define the era of online video, so let's take a look at their most popular videos of all time. We first did this list in August 2007, at which point Evolution of Dance by comedian Judson Laipply was number 1 with nearly 56 million views. The next update was September 2008, when Avril Lavigne's Girlfriend pop music video was number 1 with 103 million page views (although commenters argued that it may have gamed the system). In January 2010, Charlie bit my finger - again ! was number 1, with 148 million views.

Our latest update shows that Lady Gaga has made a big impact in 2010 on YouTube, with 2 entries into the top 10 - including the number 1 video of all time! Perhaps a sign of the times that she shunted Susan Boyle out of the top 10. Here is the top 10, as of July 2010:
