Campaign Viral Chart: Zombies rule in Walking Dead ad

The ad, which sees actors take to the street in full zombie make-up has now been viewed more than 2 million times and has inspired 100 blog posts.

Olympic sponsors P&G find themselves taking bronze, appearing in the chart once more with an ad centred around American gymnast, Gabrielle Douglas.

The ad is one of two in this week's chart from agency Wieden & Kennedy, the second for Nike reaching seventh place with more than 18,500 shares.

With less than 100 days to go until Americans vote for a new president, rivals Romney and Obama are both featured in the chart.

Incumbent president Barack Obama presents his vision for economic growth directly to camera, while Romney's ad interviews a small car manufacturer whose businesses was allegedly ruined by Obama's bailout of General Motors.

Though in tenth place the Obama ad sits six places lower than Romney's, it has been viewed more than 1.8 million times more.

The chart, produced in conjunction with Unruly, ranks ads according to the number of times they have been shared on Facebook and the blogosphere.

Ads launched more than 30 days ago are not included.
