Audience measurement firm comScore’s March 2010 study of social networking access via mobile browser concludes that mobile access to Facebook has increased 112% in the last year, while Twitter has increased 347%. Nearly a third of smartphone users accessed social networking sites through their mobile browser in January, up more than 8% from a year ago.
Facebook’s mobile browser audience surpassed MySpace in February 2009, three months earlier than the Facebook audience exceeded that of MySpace on the non-mobile web in May 2009.
These figures do not include access of the social networking services by the nearly 6 million mobile phone owners who do so exclusively through mobile applications.
