Google has started showing ads on the Google News Search Results page.  The following is taken directly from Google’s blog site:

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.
