One thing is for sure: the only artist that has benefited from performing at the VMAs is Britney Spears. Only her single has climbed big time on itunes. Rihanna the supposed slayer (says a few of her stans and nobody else) and queen of singles that is still in her 20s has not benefited at all. That said, Britney is/was a marketing product so I´m not defending her lack of talent.
