The world of mobile technology currently has its eyes on Millennial Media’s latest Q3 report, one of the largest remaining independent, mobile ad networks around. As expected, Google’s Android towers above the rest, accounting for 56 percent of the impressions in Millennial’s network, spanning its Connected Device and Smartphone OS Mix. Android market share was at 54 percent last August. iOS tails Android, but not so closely, with only 23 percent of network impressions.  This isn’t supposed to be a major blow to anyone, as Android runs across virtually everything that isn’t iOS.

Talk about lagging, RIM comes in with only 13 percent market share, Symbian with only 1 percent, and Microsoft’s Windows Mobile and Windows Phone platforms combined with only 1 percent as well.

But not all is lost on iOS, as its devices remain leaders in the mobile space.  On top of iOS boasting a 60 percent year-over-year growth for Q3, iPad impressions grew by 456 percent, and iPod Touch’s by 30 percent. The iPhone accounts for 54 percent of impressions on the iOS platform. All in all, smartphones account for 72 percent of impressions in Q3.  Apple is also the number one device manufacturer for Q3 with a 23 percent impression share among the top 15 manufacturers, and 12 percent among the top 20. It is followed by Samsung (16.48 percent), HTC (15.5 percent), RIM (11.05 percent) and Motorola (10.7 percent). WiFi dominates the carrier mix with 59 percent of smartphones impressions connected to the wireless network service, boasting a 23 percent quarter-over-quarter increase.

As for ad spending, Android takes the lion’s share of 49 percent with 20 percent increase quarter-over quarter, while Apple tails closely with 41 percent. The application Category on Millennial Media is dominated by game apps, followed by news applications.

It’s little surprise gaming remains such a lucrative category for ad spending, and growth in this sector is encouraging the entire mobile industry.  Earlier this week we learned of Appcelerator’s acquisition of Particle Code in an effort to make its cross-OS Titanium platform more inviting to game developers.  Google’s anxious to grow its gaming support as well, with game controller support to be included in Android 4.0 Ice Cream Sandwich.
