You have to counterbalance that with the fact that they've become the homepage of the internet for a large proportion of the internets users. Google is now a habit which any potential competitor will find very very hard to break. Not impossible, but in my opinion unlikely. They're going to feel the pinch no doubt but I don't see them going out of business any time soon. As long as there is the internet there will be advertising.
They've got all of their revenue from one spot that has potential to vanish - adwords.
