BREAKING NEWS: Shakira is quite popular on YouTube. But the latest story about her online success is about her song ‘La La La’, whose music video doubled as an ad for Activia yoghurts. Online video firm Unruly has been analysing the most-shared ads across Facebook, Twitter and blogs, claiming that Shakira’s video has been shared nearly 5.4m times so far, beating Volkswagen’s 2011 Super Bowl ad ‘The Force’, which was the previous record holder. Ad Age says ‘La La La’ is part of a wider trend called – ugh! – “Trackvertising”, where brands team up with musicians to release music videos that are also ads. “Music videos are by far the most-shared type of content, so it’s no surprise that brands are now blurring the lines between traditional ads and music videos in order to get themselves seen and heard on social,” said Unruly’s Sarah Wood.
