Microsoft is planning full-screen advertising within its flagship Windows Live Messenger product. “Videos will be provided by Microsoft's MSN Video service and will include movie trailers, local news clips and product commercials. The latest internal build (15.3.2689.110) for Windows Live Messenger 2010 compiled only last week contains the new advertising. When users first launch the client they will be presented with a pop over video commercial with an option to cancel the advert (clicking on an X). The commercials pop-up and cover the contacts list until a user skips the advert or waits until the 30 second commercial has finished,” revealed.
