It looks like Google AdSense the new feature powered by Google News. If you are you looking for additional ways to engage your users, Google introduce you to their recently released Google News–based element for webmasters and developers.
This element will allow you to easily integrate headlines and previews from Google News into any page to supplement your content and help make it more dynamic. Whether your site’s visitors are interested in business, entertainment or fashion, you control the types of stories in your personal news show. You can input keywords like "Obama" or broad topics like "world news" or "politics".
