Thanks for reading my post.
I've integrated AdMob ads to my apps. I have seen there are many free Android Apps out there which show Google Ads rather than android ads. By Google ads I refer to the adverts which have a letter 'g' next to the ad bar (Apps like Advanced Task Killer and Gem Miner show this kind of ads.). I went searching for what this service is but did not find anything on the web. Is this some kind of service provided by Google Adsence?
