Friends-turned-enemies Apple and Samsung may have duked it out in court, but the battle between these two smartphone makers is playing out amongst consumers, too.  The iPhone and the Samsung Galaxy S are blowing away the competition, dominating chart after chart on Millennial Media’s latest MobileMix report.

Apple remained the leading manufacturer on Millennial Media’s mobile ad platform, with more than 31 percent of the impression share.  The iPhone also remained the leading individual mobile phone.

But Samsung continues to close in the gap, with their devices representing 22 percent of impressions, with a whopping 8 devices in our top 20 mobile phones.  All Samsung phones in the top 20 list rose in position compared to where they were in Q1, demonstrating their widening influence. Samsung’s recently launched Galaxy S3 upset the iPhone 4S for the first time, becoming the top-selling smartphone in the U.S., reads comScore’s latest MobiLens service report.

An interesting exception, however, is RIM.  Many think the smartphone maker is drowning in market share loss, but the company had five devices on the top 20 list, including the BlackBerry Curve in the number two spot ahead of Samsung’s Galaxy S. Combined, RIM’s BlackBerry devices account for 14 percent of Millennial Media’s total ad impressions.

Android outpaces iOS on all connected devices

Despite widespread fear that Android will lose its relevancy after Apple’s court win against Samsung, Android remains the dominant OS on Millennial Media’s network.  Google’s mobile OS captured 46 percent of all ad impressions in the second quarter, eclipsing Apple’s iOS, which accounted for only 34 percent.

Looking at the second quarter as a whole, Millennial Media crowned the Google OS platform in the connected device and smartphone category, which includes both tablets and phones. The increasing number of Android-based devices, by different manufacturers, at a range of price points helps increase adoption.

While the catalog of connected devices continues to grow, smartphones remain the most prominent, making up 74 percent of overall ad impressions on Millennial’s network.  This is a growth rate of eight percentage points compared to the same quarter last year.

More connected devices on Wi-Fi

That’s not to say tablets haven’t been getting any love lately.  Tablets are on the rise, and they’re connecting mostly over Wi-Fi, not 4G or LTE.  Impressions coming over tablet Wi-Fi networks increased month-over-month, accounting for 95 percent of all impressions.  The Apple iPad, Samsung Galaxy Tab, and the Amazon Kindle Fire remain the top three tablets on the Millennial Media platform, which is good news for the Kindle Fire HD, which just went on sale on Amazon’s home page.

Though most tablet owners also carry a smartphone and sometimes a third and fourth device, the proliferation of tablets popping up on Millennial Media’s network show a telling sign of network behavior.  Ninety-five percent all tablet impressions on Millennial’s platform came over Wi-Fi in the second quarter, showing the clear opportunity Wi-Fi networks have with the rise of connected devices.

It’s often said by members of the Wi-Fi industry that their services are the saviors of the data conundrum faced by all wireless carriers today, and an undeniable increase of Wi-Fi hotspots across the country (and world, for that matter) is an important development for the emerging data infrastructure, as SiliconAngle founding editor John Furrier calls it.

Apple crushes it in ad impressions for connected devices

While Android is the ruling OS across connected devices, Apple’s streamlined iDevice family reels in the most ad impressions, with a 31.38 percent market share in both mobile phones and tablets categories. iOS also scored first place in the category of connected devices, which covers the iPhone, iPad and devices such as the iPod Touch.

Samsung claimed second place with a 31.97 percent share, while RIM is in third with a 13.49 percent, followed by HTC (8.79 percent), and Motorola (6.97 percent).

Microsoft is slowly gaining some momentum, registering a share of 3.31 percent.  At the recently concluded IFA event, various manufacturers show interests in the upcoming Windows 8 OS, which will help the Redmond company to revive its overall mobile market shares in the coming months.

Games appeal mobile device users

One area Microsoft will build its Windows 8-based, mobile cloud strategy around is gaming.  Overall, smartphones continue to surge in popularity of gaming applications among consumers, according to Millennial’s report. Thousands of game applications available on various OS platforms establish the category at the top of the mountain, attracting a diverse crowd that’s willing to pay to play.

Music and entertainment remained the number two mobile application categories, with downloads, TV guides, and channel lineup applications trended strong in the second quarter. It was followed by Science & Technology, Books & Reference and communication applications.

The booming connected devices trend has wholly changed the music and entertainment industry. According to a recent report from Gartner, worldwide mobile display advertising spending is expected to grow from $1.8 billion in 2011 to approximately $13.5 billion in 2015.

Millennial Media’s recent Mobile Intel Series: Entertainment report also highlighted how entertainment brands are using mobile to reach and engage consumers.
