eMarketer: Instagram will bring in $595 million in mobile advertising revenues worldwide this year, according to eMarketer’s first-ever forecast of how much advertisers will spend on the social network. By 2017, Instagram’s global mobile ad revenues will reach $2.81 billion, accounting for over 10% of parent company Facebook’s global ad revenues, e Marketer said. “Now that Instagram is opening up, there is a lot of pent-up demand. The rollout of new features over the next several months means that by the end of 2015, Instagram will have a host of new ad products for advertisers large and small.”
