during the Iowa primary election coverage, CNN's Anderson Cooper held up a "magic pie chart." Jon Stewart showed the clumsy use of the technology on The Daily Show. it's actually an application of Augmented Reality, but the BBC was the first group (I know of) who used it for election coverage.
I haven't been able to find any images of the CNN example, so if you're reading this and you know of one, please post a comment.
update: wow, thanks to datadreamer for the quick reply.

- Bill Gates tries out an ARTag AR system that uses a head-mounted display (our AR book uses ARTag but does not require anything other than a Windows PC and a webcam)
Mark put this short video up on YouTube, it's a good demo of what we're talking about in our book: http://www.youtube.com/watch?v=ItOtTdhDoto
