Just opened up the MSN UK Portal (http://uk.msn.com/) and noticed that there's now a Full Page Live Earth Interactive Flash Ad, which can be seen by clicking your mouse in the top right hand corner. I'm not sure if this is the first time it's ran but I didn't see it before any of the Live Earth Concerts, only after.

On another note I noticed that the Main MSN Portal (http://www.msn.com/defaultO.aspx) once again has the interactive Microsoft Office 2007 advertisement.
