Viral Video Chart: Brad Pitt's World War Z trailer, John Lewis's snowman and turbo-charged tractor racing
The first trailer for Brad Pitt's new zombie flick World War Z has shot to the top of this week's Viral Video Chart.
Almost 200,000 social media users have shared Paramount's teaser for the zombie film, which shows Pitt battling against the undead on the streets of a US city (which is actually Glasgow).
Elsewhere on the Brand Chart, John Lewis's emotive Christmas ad clocks in at number three and chart favourites Samsung and Red Bull return with new virals.
And if you thought tractors were those slow decrepit machines that clog up narrow country lanes, then think again, as Mikael Karlsson's turbo-charged racing traktor takes top spot in this week's User Generated Content chart.
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.
