More from the new Zenith report (read it here) which says online video advertising is growing almost as quickly as social media, at 18% a year. Zenith predicts that by 2019 online video will total $35.4 billion across the world, edging out radio which Zenith pegs at $35 billion. Zenith says it’s becoming common for brands to use online video as a complement to television, but not as a substitute. Even with the growth, online video advertising will be less than a fifth of the size of television advertising by 2019.
