Your entire campaign.One screen.

Plan the media buy, review the creative, follow delivery and measure the results. PRISM brings the four stages of a digital out-of-home campaign into one workspace.

PRISM campaign dashboard showing performance metrics, audience targeting and a map of advertising screens in Rome.

The same campaign, four times.

One campaign, opened at four points in its life: while it is being planned, while the creative is in review, while it runs, and after it has finished.

True Stats.

Opportunity to see (OTS) estimates potential exposure. Weather, traffic, roadworks and local events can change the conditions around a screen.

True Stats explores how to incorporate those conditions into campaign reporting.

Contextual estimates are not a count of people who actually looked at an ad.
