Earlier this week comScore reported that mobile devices (smartphones + PCs) were responsible for 60 percent of total digital media time in the US (chart at right). Traditional TV is still the king in the US in terms of overall consumer time spent.
More specifically, comScore said that US users spend 51% of all their digital media time in mobile apps. The firm reports roughly 83% of mobile media time is app-based (vs. the mobile web). Nielsen puts the number at 89%.
I spoke to comScore at some length about these numbers. We agreed that ad dollars would eventually follow the consumer traffic migration. The question is how long it might take. For the past few years mobile ad spending in the US has roughly doubled YoY (per the IAB):
Total digital ad revenue in the US for 2014 will probably be around $49 billion. If time spent and ad spend were aligned mobile would capture more than half of that number (and in-app advertising the bulk of that). Accordingly mobile ad revenue would be $29.4 billion and PC ad revenue would be $19.6 billion.
That would be radical.
