Micro-blogging platform Twitter has beaten rival Facebook in this year's mobile ad revenue market in the United States,according to a survey. The report by the research firm eMarketer said Facebook,which just rolled out mobile ads for the first time this year,would likely overtake Twitter by 2013. According to the Telegraph.com.au,Twitter gets revenues from mobile through so-called "promoted tweets," which make up a large portion of the firm's revenue. The survey indicated that Facebook was expected to see some 72.7 million dollars from mobile ads,just behind Apple's 75 million dollars. However,eMarketer forecasted that Facebook will rise to number two in the US market by 2013 with 387 million dollars in mobile ads and will take in 629 million dollars by 2014. Facebook gets most of its revenue from its Marketplace advertising platform,mostly ads that display on the right-hand side of Facebook's desktop experience,but not mobile,the paper said.
