Some of these pop stars are artificial inflating their video views on Youtube to make themselves appear more popular online. Youtube chiefs recently stripped 2 billion views from pop videos on its site amid fears the figures were faked.
Rihanna, Justin Bieber and other music stars under Universal Music label lost 1 billion views.
Rita Ora, Alicia Keys, Labrinth and other music stars under Sony Music label lost 850 million views.
Michael Jackson's feed lost 287 million views, while Beyonce lost 151 million views
Youtube stripped the views without suggesting the music stars or their labels were directly involved in artificially inflating them. Some fans who are hackers could have inflated them, or maybe the labels paid the 'hackers' to take up the numbers.
