Programmatic video is hot, and getting hotter. According to eMarketer, in 2014, advertisers and publishers spent an eye-popping $700 million on programmatic video. By the end of this year, that number will triple, topping a cool $2 billion. Everyone wants in on the action (including brand marketers). And why not? Video ads deliver great performance, and can pack a lot of storytelling in a matter of seconds (as Budweiser’s "Lost Dog" Super Bowl ad makes clear).
