Google Maps Ads

Google has added ads to its map service long ago but it is till recent that they try to target the ads according to locations. Not only that, ads will now show up on the map. And the advertisers can even provide a small square image so that it appears in the ad bubble. Thought I am not living in the US, I still feel excited for this feature. I would even suggest Google to add the latest 'click-to-call' feature to ads (yet the pricing system for this kind of ads should be CPM as I wouldn't click on the ad if I could ask for details about the company on the phone.)
