COLOGNE — The odds are still stacked in publishers paper when it comes to selling online video advertising, industry executives continue to observe.

“One thing that continues to be true is the scarcity of quality video inventory, which is a blocker for more widespread adoption of online video,” GroupM’s programmatic unit Xaxis’s UK MD Nicolas Bidon tells Beet.TV in this recorded video interview at DMEXCO.

“The sell side has inventory but they’re being quite selective about who they want to partner with. “The guys who have the quality inventory only want to work with the best, most reputable brands and the people who they can strike long-term relationships with.”
