Sephora First to Leverage “Personal Primetime” Through Flipboard StoryboardToday, Flipboard launches Storyboard™, a new ad experience that enables brands to tell powerful and complete narratives using multiple native formats—stitching together articles, images, animated .gifs, video, and audio— to the social magazine’s 90 million monthly readers. Sephora is among the first brand partners to roll out Storyboard campaigns, connecting with premium audiences while they’re engaging with stories about their passions and interests in a beautiful mobile environment.
