Facebook Inc's Instagram is bringing more than 30 advertisers into one of its fastest-growing features, Instagram Stories, in a bid to boost advertising revenue, the company said on Wednesday. The social media company will become a more important player in maintaining Facebook’s growth in advertising revenue in 2017. During the last two earnings calls, Facebook executives said they may soon reach a limit on the amount of ads they can place before users, one of the factors that had driven ad revenue growth.
