Clients want to know what works. Often times we're justifying DSPs based on transparency vs. service. What's the value of the ad network if they can't give us transparency? "The blind ad network died
this year," says Mark Papia, senior vice president of marketing at FOX Interactive Media. "Regardless of the ad network, you're getting full transparency, and if you're not you are probably working
with a media verification tool," he says. "The data ties to publishers. Transparency exists in both worlds for media folks. Anthony [Katsur, general manager at Mediamath] said ad networks are only as
good as the ad networks they tie to because the DSP folks aren't on the phone trying to find the latest publisher."
