Telegraph: The growing popularity of mobile devices has helped Google increase its dominance of global advertising revenues, with the web search giant’s income from media spending more than twice its nearest competitor. Google had media revenues of $50.6 billion in 2013/14, dwarfing the next largest player, Disney, at $20.3 billion, according to a new report by ZenithOptimedia. However, the main beneficiary of the transition to mobile has been Facebook, the report said, describing the social media website as the “fastest growing” on the media list. According to ZenithOptimedia, Facebook accounted for over a quarter of all advertising spending on mobile devices.
