• We forecast that online video ad revenue will reach nearly $5 billion in 2016, up from $2.8 billion in 2013. That represents a compound annual growth rate of 19.5%. For comparison, TV ad revenue will decline by nearly 3% per year during the same time period.
  • Online video ad views exploded in 2013, topping over 35 billion views in December, about three times the number of views in the same month a year earlier. Video ad views averaged over 100% year-over-year monthly growth during 2013, compared to 77% in 2012.
  • Online video ads are significantly more expensive than other digital ad formats due to a lack of inventory, but prices are steadily declining as more publishers rush into video, and placements open up. 
  • Video ads are high-performance — they have the highest click-through rates of all digital ad formats, at an average CTR of 1.84%.

  • Streaming devices and connected TV accounted for just 2% of online video ad views in the fourth quarter of 2013, but companies like BrightLine are experimenting with formats to grow this new niche market.
