"Spending on media continues to shift from traditional to digital products and services at a rapid pace. By 2019, we believe digital spending will account for more than 50 percent of overall media spend. Within this, digital video spending will overtake physical spending by 2018, two years earlier than we had previously forecast. Digital, consisting of Internet and mobile advertising, will become the largest advertising category by 2017, surpassing TV one year earlier than forecast, and mobile will more than double its share of the digital ad market. This rapid digital shift is being driven in part by the growing number of connected consumers, the expansion of mobile telephony, and elevated mobile broadband adoption." (Page 5)
