Mobile entertainment provider GoTV Networks Inc. has made moves to an ad-supported model with partnerships with three mobile entertainment and advertising firms. The Sherman Oaks-based company currently makes its programming available through subscription only but sees in the long-term that ad-supported content is the direction mobile is headed. Signing agreements with Millennial Media, digital SIDEBAR and Ad Infuse is part of GoTV’s strategy, said CEO Thomas Ellsworth. “Today the nascent signs of the inevitable market shift to ad-supported mobile content are coming into view. As part of that dynamic, we see a multi-faceted advertising strategy being critical to our success,” Ellsworth said. “This includes targeted on-device ad technologies.”
