Android remains top dog among all mobile platforms as seen by mobile ad network Millennial Media.
For the second quarter of 2013, Android snared 51 percent of all ad impressions on the network, according to the latest Millennial Media Mobile Mix report released Friday. That number was up from the 46 percent seen in the second quarter of 2012 and from this year's first quarter.
iOS remained firmly in second place. But it showed a healthy gain in ad impressions, rising to 42 percent last quarter from 34 percent in the same period last year. Combined, Android and iOS snagged 93 percent of all impressions, leaving little room for other mobile platforms.
BlackBerry OS saw its share fall to 7 percent from 15 percent. Windows Phone and Nokia's Symbian, which scored 4 percent and 1 percent, respectively, in 2012's second quarter didn't even register a blip last quarter.
Among device makers, Apple continued to reign with 39 percent of all ad impressions. The iPhone was the leader with a 22 percent share. The iPad and iPod Touch took third and fourth places, respectively, among the top 20 devices.
Samsung followed with a 26 percent share thanks to its Galaxy S smartphone, which was the No. 2 device among the top 20 with a 9.8 percent share. The Galaxy Note also proved popular with a 44 percent gain in its ad impressions.
