Millennials and teens want the marketing on their social platforms to match the content they already see there. To that end, Tumblr has handpicked a group of their site’s successful artists to join the Creatrs Network, which will help brands to create ads that fit in naturally on Tumblr’s GIF and image-heavy feeds. The group will work with advertisers to create nonintrusive ads that “its users never even notice,” and that are so attractive they will hopefully want to share. A small part of the Creatr Network works on “GIFing major events,” and Tumblr says that it has already paid $250,000 to these members. (The Verge)
