Another month, another report from advertiser Millennial Media. As usual, it's best to start this off by pointing out that these results are based on ad impressions across Millennial's network, and thus should be considered a sample. With that out of the way, let's take a peek.

The two most significant things that stand out to me are that Android is now tied with iOS for the largest smartphone OS, and Android accounts for a whopping 54% of ad revenue on the network, versus 39% for iOS. Pretty damn impressive.

Among application publishers who are adding support to new platforms, Android is the fastest growing, though that is something that is probably common sense if you really think about it (given that iOS already has a very large developer following).
