It doesn't affect Adwords for search results. That is the real cash cow that is growing each year by double digit percentages.
Doubleclick and Adsense on the other hand are starting to slow down and make up less share of Google's overall revenue [1]. In 2004 it was 50% of their revenue, now it's 20% and it's probably going to shrink even further as AdWords revenue and other revenues(cloud, apis) increase.
