Google is definitely looking to expand its revenue sources, after allowing third-party advertisements onto its network, the company has announced the launch of Adsense for RSS feeds through Feedburner, starting with selected few publishers this week the company plans to roll-out the product to all publishers soon.

According to the official blog post:

"..publishers already in the FeedBurner Ad Network will continue to see premium CPM ads directly sold onto their content, but with the added bonus of contextually targeted ads that will fill up the remainder of their inventory. That means you get the best of both worlds: a dedicated Google sales force that knows how and why to sell onto your content, with the added revenue that full back-fill coverage provides. And with AdSense, you'll know that your back-filled ads are using the strongest contextual ad engine, ensuring the most relevant and profitable ads are delivered to your subscribers. And yes, ads are also sold via Google's AdWords program.
