NEW YORK — While rich media display ads comprise just 6 percent of Web advertising now, that number will vastly increase as the cost and complexity of serving comes down, says Barry Salzman, Google's Managing Director of Media and Platforms, the Americas, in this video interview with Beet.TV

Salzman says that rich media, including video display advertising, will appear on "hundreds of thousands of sites" and will create a $50 billion market by 2015.

In 10 years, he predicts that video advertising will dominate the Web; he tells us "every kind of ad format becomes a video format."

We caught up with him after his keynote address yesterday at the IAB's MIXX conference.  Salzman and Google's Neal Mohan presented the "Seven Predictions" of display advertising.
