My hunch – Google Analytics being used as the central place to collect information on all Google's products and services seems to be more and more true as time passes.

First AdWords stats was integrated with Google Analytics, and now Google Gadgets stats are showing up from within Google Analytics  according to Steve Rubel - but only for the developer of that Gadget/Widget – which makes sense.

…The most popular widget (which Google calls gadgets) is for Google Maps. It generated 4.8M weekly page views.

In addition, Google now gives developers the ability to track both page views and interactions using Google Analytics. Hopefully Google will start to release more of this information publicly the way it does for videos that are on Google Video."

It's only a matter of time till the DMarc Radio Advertising stats AND AdScape In Game Advertising stats also show up in Google Analytics.
