Third Party (Google-certified) Ad Networks In AdSense

AdSense announce that now publishers in North America and Europe are able to publish ads from Google-certified ad networks on their websites.

These ads will compete with AdWords ads, and will help publishers earn the most from every ad impression by increasing competition. At the same time, publishers will have full control over which ads and ad networks can appear on their pages.
