So we had a three way race open up in the U.K. between iOS, Windows Mobile and BlackBerry. But starting in 2009, Android entered into the picture. Google's open source OS started to team up with iOS to squeeze the market share belonging to Windows Mobile, and later, Windows Phone.
According to the chart, as of this past March, BlackBerry still owned a higher market share than Windows Phone in the U.K. And to make things look even worse for Microsoft's mobile OS, the graph is based on consumer data only. That means that BlackBerry 's share of the U.K. smartphone market topped the figure for Windows Phone as recently as three months ago, even without taking into consideration the phones purchased by the enterprise. The latter, of course, is BlackBerry's bread and butter.
