Windows Phone Overtook BlackBerry in 2012

Last August, Windows fan site

predicted that domestic sales of Microsoft's

Windows Phone platform would overtake BlackBerry

by November 2012.

The publication came to this conclusion after analyzing data from StatCounter, which showed a steep downward sales trend for BlackBerry devices. At the same time, Windows Phone devices were beginning to pick up in sales, but at a much slower pace than BlackBerry's declines. Two weeks ago the

reported that Windows Phone had topped BlackBerry sales in Europe late last year. Now researchers at

claim that Windows Phone became the third-biggest smartphone platform in America during the fourth quarter. "Microsoft Windows Phone overtook BlackBerry OS to become the third largest smartphone platform in the influential United States market during Q4 2012," analyst Neil Mawston wrote in his summary. "It was the first time Microsoft has surpassed Blackberry since 2006." Mawston also said that Android "lost share in annual terms for the first time ever." His research corresponds with an

claiming that Apple

raised its domestic market share to 53 percent during a 12-week period that ended on November 25. Investors do not seem to be too worried with this report, however, which only includes sales that occurred

has been accused of doing the same thing but on a much larger scale. When the iPad 2 was released, Benzinga discovered that some Apple Store locations sold no more than a couple of units per day. One year later, the third-generation iPad launched with

-- and very few sellouts. When Sony

launched the PlayStation 2 in North America, the company shipped

. All were sold on the first day of release. Meanwhile, the console was readily available in Japan, causing many to wonder why the company did not ship more units to North America. While Apple, Sony and BlackBerry are unlikely to admit that these shipment tactics were driven by strategy, it should be noted that supply shortages do not equal sales success. However, in the case of PlayStation 2 and the second-generation iPad, this strategy -- intentional or not -- worked beautifully.
