CHICAGO  –   Having  a clear set of analytics around where video ads appear on publisher pages has become essential to advertising agencies who are demanding more accountability.   This movement has lead to the introduction of “viewability” tools from several players including Tremor Video’s VideoHub, a consortium lead by TubeMogul and a product from Vindico.

The new comsCore product was first introduced with VideoHub.

Now, comScore is rolling out its own viewability product, says comScore co-founder and executive chairman Gian Fulgoni, in this video interview with Beet.TV’s Ashley Swartz.   We spoke with him last week at our leadership summit on programmatic video advertising where he was a participant.
