Google today opened up its 9-month-old pilot program to allow qualified publishers to put video ad units on their sites. The AdSense for video beta will use the InVideo ad units which Google uses on YouTube. Unique to the AdSense for video ads will be a text overlay element, a text ad contextually targeted to signals in your videos and on the page where the video lives.
AdSense for video is now available to U.S. publishers with English language sites who serve at least one million video streams a month. In the near future, Google plans to expand the program to more publishers of various sizes and locations.
