CHICAGO — Given the increasing interest from premium publishers in programmatic buying, video ad marketplace SpotXchange is betting that more than one-quarter of all video ad spend will be of the programmatic variety by 2014, says Jeremy Straight, Senior VP Business Development at SpotXchange in an interview with Beet.TV.

Digital video ad spend is slated to hit $4.6 billion next year, up from $3.6 billion this year, he says, citing Forrester statistics. Real-time buying should comprise $686 million this year and surpass $1 billion next year. “We view RTB as a buying mechanism within the programmatic ecosystem,” he says.

We interviewed Straight in Chicago at the VivaKi  offices. Straight was a participant in the Beet.TV Programmatic Video Advertising Summit hosted by VivaKi and presented by TubeMogul.
