Android continues to up its lead over Apple's iOS, according to the latest Mobile Mix report from ad network Millennial Media.
Google's OS captured 61 percent of all ad impressions on the mobile ad network in July, a healthy gain from 54 percent the prior month. On the flip side, Apple's iOS lost some share last month, dropping to 21 percent of all impressions from 26 percent in June. Android has held onto its leading spot for the past eight months since overtaking iOS this past January.
That left Research in Motion's BlackBerry with 14 percent of all impressions, followed by Nokia's Symbian and Microsoft's Windows Mobile, each with 2 percent.
