If you're in the US, starting today you may notice something a bit different when you search Google News.

Last November, we announced plans to begin experimenting with ads on a number of Google properties, including news query refinements within Google search. Today, we're continuing a similar experience for users by introducing ads on Google News search-results pages in the US. What this means is that when you enter a query like iPhone or Kindle into the Google News search box, you'll see text ads alongside your News search results--similar to what you see on regular Google searches or Google Book Search.

In recent months we've been experimenting with a variety of different formats, like overlay ads on embedded videos from partners like the AP. We've always said that we'd unveil these changes when we could offer a good experience for our users, publishers and advertisers alike, and we'll continue to look at ways to deliver ads that are relevant for users and good for publishers, too.
