Did you see it? Two days ago Instagram did a sponsored post for Tiffany and Company that had a new feature, multiple images. It works very similar to how Facebook shows you "suggested pages" and "pages you make like" on their mobile app. You have to swipe left to see more.
It does grab your attention and we are sure it increases engagement for the advertiser. Unfortunately their ad program is only available to major brands but like all small businesses we are hopefull to get our fair share of the instagram audience.
