Tanya Dua:

When Coca-Cola wanted to push iced-tea drinkers to consider its Gold Peak brand this summer, it didn’t target people like most brands do by using their search history. Instead, it combed through consumers’ photos on Facebook, Instagram and Twitter and served them ads based on images they shared on those platforms.
 Gold Peak tapped into an image recognition engine that identified people who posted images that featured glasses or jugs of iced tea, displayed emotions such as happiness and excitement as well as contained cans or bottles of its competitors, including Snapple, Honest Tea, Lipton and others. Those people were then served Gold Peak ads on 40 mobile sites and apps after leaving Instagram, Facebook and Twitter.
 For example, if you posted a picnic table spread with a jug of iced tea somewhere in the mix on Instagram, Gold Peak could have targeted you with ads while you read an article on Business Insider or checked the weather on the AccuWeather app in the past month, thanks to your photo.
