Horizon Media, the largest independent media buying agency, is working with the Adap.tv to manage online video ad inventory around current and future pricing, says Mary Shirley, VP of Digital Activation in this interview with Beet.TV.

In making online video more efficient for clients, including Geico, Horizon is using a number of measurement tools, she explains.

The alliance with Adap.tv was announced last month.

We interviewed her at the company's downtown Manhattan offices.
