Report: Digital Ad Spending to Overtake TV by 2017

Reuters: Surging growth in advertising via mobile phones and tablet computers will help Internet advertising overtake television as the dominant medium for global ad spending by 2017, a leading media buyer forecasts. Zenith Optimedia, owned by advertising agency Publicis, said that it expects mobile advertising — via smartphones, iPads and other tablet computers — to more than double its share of global ad spending between 2014 and 2017, to 12.9 percent. It would contribute 70 percent of growth in all advertising spending over that period.
