Microsoft's Windows Phone mobile operating system has surpassed BlackBerry in yet another market stat.
Surveying all recent Web traffic generated by smartphone operating systems in North America, Chitika found that Windows Phone finally inched past BlackBerry to earn the No. 3 spot behind Apple's iOS and Google's Android operating systems.
From February 1 through April 30, Windows Phone's share of traffic actually stayed flat at about 1 percent. But BlackBerry's share dripped from 1 percent to 0.8 percent, pushing the phone maker down to fourth place in March, according to Chitika.
These Web traffic stats follow market share reports from the likes of IDC and Gartner showing Windows Phone shooting past BlackBerry to achieve third place in the global smartphone arena. iOS is still the top dog, according to Chitika, with 53.1 percent of North American Web traffic. Second-placed Android isn't too far behind with 44.5 percent.
To derive its data, Chitika looked at hundreds of millions of ad impressions among smartphone owners in the US and Canada from February through April.
