David Beckham's photobooth surprise and brilliant Boris Johnson Olympics spoof top the Viral Charts
London 2012 sponsor Adidas has taken top spot in this week's Viral Chart with its video of David Beckham surprising fans in a photobooth.
Becks' guest appearance has been shared 22,300 times on Facebook, more than 5,000 times on Twitter and is closing in on two million views on YouTube.
Adidas's top spot means arch rival Nike has to settle for the runner-up spot in this week's Brand Chart.
As it is not one of the Olympics' official sponsors, Nike's 'Find Your Greatness' video aims to get around tough ambush marketing rules by showing competitors competing in various places called London (but not that one) around the world.
There's also a distinct Olympic theme to the User Generated Content chart this week as mash up master Casetteboy brilliantly satirises London Mayor Boris Johnson's welcome to the Games.
The charts are compiled with the Viral Ad Network and are based on the number of shares each video has received on social media over the last seven days.
