Twitter Outshines Facebook With Earlier Focus on Mobile (Bloomberg)
Twitter Inc., the microblogging service that plans an initial public offering, is outpacing its bigger competitors Facebook Inc (NASDAQ:FB) and Google Inc (NASDAQ:GOOG) in a crucial growth area: mobile advertising. Ads on smartphones and tablets will make up more than half of Twitter’s ad revenue this year, according to EMarketer Inc. That puts it ahead of Facebook, which generated 41 percent of its ad revenue from mobile promotions in the latest quarter. Google, the largest search engine, is estimated to get slightly less than one quarter of its revenue this year from mobile ads, EMarketer said.

Autoplay Might Be The Problem With Facebook’s Video Ads (Forbes)
