Blip.tv CEO "Mike Hudack revealed that his company has found a way to dynamically insert ads from DoubleClick into video downloads on iTunes and elsewhere," the Washington Post reported.
Given the huge use of the tube sites such as YouTube and the increasing popularity of downloading ITune videos this new technology should prove a good revenue source for Google - owner of DoubleClick.
"For the past six months or so, blip.tv has been experimenting with placing pre-roll, post-roll, and overlay ads in some iTunes videos. These ads are served by DoubleClick and have hyperlinks that make it easy to track when somebody clicks on an ad," the Washington post noted. Videos downloaded to Ipods and other offline players will not be tracked at this stage - though given the synching technology this could be adapted to soon.
