Search engine giant Google said this morning that it has launched a beta of a version of the firm's AdSense advertising technology for video. The new advertising program allows video publishers to include non-intrusive advertising in their video streams. Among the companies participating in the beta of the Adsense for Video program are Los Angeles-based MyDamnChannel and Revver, and San Diego's Eyespot Network, in addition to Demand Media's eHow.com web site.
