Smartphone market grows in June; Windows Phone, BlackBerry see largest gains

Millennial Media has released its monthly report on the smartphone market, and, as expected, the market has continued to grow as a whole. What might be less expected is which platforms ended up gaining the most relative growth.

In the smartphone OS wars, Android continued its lead in the market, followed by iOS. Both platforms grew their impressions on Millennial's ad network - by 11 and 18 percent respectively. What may be surprising is the growth that BlackBerry and Windows Phone 7 had, which was 29 percent and 31 percent respectively. Of course neither platform, especially Windows Phone 7, has near the market share that Android or iOS have, but it is interesting to see them growing, rather than retracting.

Over on the device rankings, the iPhone is still the top smartphone on Millennial's network, followed by diehards BlackBerry Curve and the original Motorola DROID. Consumers are unsurprisingly using "connected devices," such as tablets, more and more, which showed 13 percent growth in impressions over the previous month, though all 20 of the top 20 devices on Millennial's network were smartphones.
