"This gives us access to top video content, plus a new source of revenue for our content partners," said at that time David Eun, vice president of content partnerships for Google.
Search Engine RoundTable has information from one of the 150 publishers that were elected by Google for the beta test.
"Google's Streaming Video Content + Ads enables website publishers to display streaming video ads and video content from MTV Networks on their own sites. Partners will receive the video and streaming video ads as a JavaScript object that will embed a Flash player on their site. Google manages all the hosting and streaming of video.
For the initial test, we will be using channels of video content provided by MTV Networks, such as from their Comedy Central, MTV, MTV2, The N, and Nickelodeon channels. The video content is mostly short-form clips of up to a few minutes in length."
The ads are provided by MTV, have around 30 seconds, are shown between segments of the video content and are CPM-based.
