While we wait for the Internet TV plug in to be made available for countries outside of the USA Microsoft are adding Interactive advertising to it. Chris Lanier says that the interactive advert is not intrusive as it just ads a "lean more" button to the advert that shows prior to the requested video. Media Center is an ideal platform for this and if it helps to get content on to the platform I am all for it.

So Microsoft can we have Internet TV please in the UK!

Don't forget that you can add user generated content to Windows Media Center with applications like Yougle
