In DC's 10-minute video, stunt driver Ken Block weaves between moving trams and skids through the city. It has been watched more than three million times in the 24-hours it has been live on the web.

Last week's most shared, Abercrombie & Fitch's lip-synced "call me maybe", has fallen into third place, beaten by both Block and a flashmob for Spanish bank, Banco Som Sabadel.

Meanwhile, an ad for Greenpeace, the environmental charity and activist network, has been shared more than 16,000 times.

The ad features the voice of Jude Law, a soundtrack by Radio Head and a homeless polar bear making its way through urban scenes around the UK.

It has already inspired more than 100 blog posts, and calls for an end to oil drilling, industrial fishing and conflict in the Arctic.

BBH and Refuge's hard hitting ad in which beauty video blogger Lauren Luke provides a step-by-step guide to disguising the bruises and scars of domestic violence, enters the chart with 3,500 shares.

WIth just two weeks until the Olympic opening ceremony, the BBC's recently-revealed London 2012 coverage ad misses out on entering the chart, which has been shared just short of 3,000 times in the past seven days.

The chart, , ranks ads according to the number of times they have been shared on Facebook, Twitter and the blogosphere.

Ads launched more than 30-days ago are not included.

Due to technical issues with Twitter's API, shares from the social network were not included in the count.
