Campaign Viral Chart: Belgian mindreader fends off Lana Del Rey

The ad highlights the dangers of sharing information online. It has been created by Duval Guillaume Modem and shared 376,868 times in the past seven days.

Samsung, last week's chart-topper, fell to second position with their ad by 72andSunny. It spoofs the Apple "superfans" queueing for the launch of the iPhone 5.

Meanwhile, an official iPhone 5 ad, created by TBWA\Media Arts Lab, has been shared 15,861 times and enters the chart in eight position. It was bested by a video for iPhone5 information blog, iPhone5.nl.

The ad, created in-house, features hidden-camera footage of people struggling to pick up a new iPhone that had been glued to the streets of Amsterdam.

An extended version of H&M's new ad, created by Johan Renck and starring Lana Del Rey, has been shared 59,484 times and comes in third.
