Google has launched its AdSense for Video pilot program to test its system to allow publishers to insert streaming video ads in online video content on their Web sites. Christine Lee, AdSense product marketing manager, said Google expects in-stream video ads will add value to publishers' sites and will help engage site visitors. The pilot program is currently closed to new publishers. "With this pilot, publishers control when the ads play in their videos and choose which videos get the ads. This pilot represents our continued efforts to address the challenges faced by publishers who want to monetize their video content, by advertisers who want access to quality video inventory, and finally by users who want ads to enhance their video watching experience, not detract from it," said Lee.
