The 'Your Potential, Our Passion' campaign has been in Microsoft for over a year now. And the first time I saw some of the to-be-telivised ads, I was impressed. It is one of the best videos I have seen in years from Microsoft.

This is a nice follow up of those campaigns:

I also like the research part, lots of that stuff you can actually see working on videos of channel9:
