[MediaPost]“Brand safety will continue to be a topic of concern in 2018, but the discussion will transition into one of brand appropriateness -- a more nuanced, sophisticated evaluation of what’s suitable for an individual brand,” says Bettina Hein, founder and CEO of video ad tech firm Pixability. “Contextual ad targeting will also make a comeback after advertisers discover the pitfalls of pure person-based targeting.How the New York Times Gets People to Spend 5 Minutes Per Visit on its Site [Digiday]Bleacher Report got people to spend more than five minutes per day in its app by introducing a tab for Vine-like video loops.

The Outline increased time spent per session by 30 percent by embedding 3-D objects into articles.
