US Online Video Ad Spending By Device, 2012-2018 [CHART]

Similar to the reasons that TV is still outpacing digital video ad spending, online video remains well ahead of ad investments in video programming on smartphones and tablets—for the time being. Overall, eMarketer estimates that online video ad spending—that is, ad spending primarily on desktop-based ads—will total $4.52 billion in 2014, or 75.8% of digital video ad spending, vs. $1.44 billion for video ad spending on tablets and smartphones. By 2018, those figures will draw more closely together, when online will still slightly outspend mobile video—$6.64 billion to $6.07 billion. Read the rest at eMarketer.
