According to Google, more than 200,000 Android-enabled devices are being activated on a daily basis - up from just 60,000 per day in February. Correspondingly, Android apps now number more than 100,000 - double the number of available apps in May. In short, Android is rolling. So, advertising is in hot pursuit.

Google's AdMob (their mobile advertising unit) is launching interactive video and interactive interstitial ad units on the Android platform. These interactive ads will automatically optimize for each user, by identifying the screen resolution, size and network connection speed.

According to the official Google Mobile Ads Blog, "AdMob interstitial ads are reserved for developers of the most popular and engaging iOS and Android apps.  These high value ad units can be placed at app-open or in-app and provide an additional option for premium publishers to effectively monetize their user base."

This is yet another sign of Android's surging popularity and another step closer to pulling even with the iPhone. It won't be long now before Apple starts hearing footsteps from every possible angle - from phones to tablets, and apps to ads.
