Combined, online display and social media advertising spend will double between 2015 and 2020, growing from €14.4 billion to €28.7 billion.
 
Among the factors driving growth, the combination of mobile and premium video advertising will drive an upsurge in demand for both online display and social advertising. Advertisers will increase their investments in video and mobile ads as media consumption evolves and targeting accuracy improves.
 
Native mobile video advertising is already proving a winning formula in the social media sphere, and publishers will take notice as they further refine their video ad offerings to provide more premium inventory, preventing a decline of video ad CPMs as supply increases. In fact, mobile ad spend will overtake PC as PC flatlines in the next five years.
 
Other developments will continue to disrupt online ad revenue in the next five years: 
  • Programmatic will become the default mechanism for trading online display
  • Ad blocking will force new behaviors on the publisher side, and a greater struggle to hit the sweet spot between monetization and consumer experience.
  • Growing rivalries between Apple, Facebook, and Google for news aggregation services will further dis-intermediate publisher mobile advertising revenue.
