The BBC had an interesting program on Google on last Friday, called ‘The World according to Google’. It is now available on the BBC website here. It doesn’t have much new material in it, but it has some interesting talking heads, including Marissa Meyer, a Google Executive, talking about the challenges that Google faces, including click fraud. A good introduction for those people not already abreast of what Google’s exponential expansion entails, both for itself and for the rest of the world.
