Major recording companies have lost more than two billion video views on YouTube after the video sharing website cracked down on alleged fake views. The biggest hit was taken by Universal, home of Rihanna, Nicki Minaj and Justin Bieber, which lost more than one billion views from its total of seven billion. Sony was second hardest hit, with the label behind such stars as Alicia Keys, Rita Ora and Labrinth losing more than 850million views in a single day.
Universal, which previously had dozens of clips on its YouTube channel, has had its offering slashed to just five - none of which are music videos or last more than about a minute and a half.
Sony's page was also left practically bare following the cull, with just three videos left.
The number of views attracted on YouTube are these days regarded as an unofficial worldwide popular music chart, and any suggestion that major labels are engaging in underhand tactics to increase their numbers could threaten the credibility of their artists.
