Lots of press about Google's acquisition of Doubleclick. I agree with Steve Rubel's assessment that this means that Google owns the end-to-end marketing relationship, from branding through to search. But also remember Google Checkout, which allows Google to close the loop on not only search but also display ads all the way through to transactions. There are privacy concerns, but if advertisers and publishers agree to this -- and they will because they will each benefit from the synergies created -- it won't be a problem.
