While quarterly losses and dropping handset ASPs gobbled up all the headlines surrounding Nokia’s earnings report on Thursday, there is another aspect of Nokia’s latest smartphone shipment numbers that shouldn’t be overlooked: Namely, that Symbian is finally dead. Asymco’s Horace Dediu has posted a chart on his Twitter account showing how Windows Phone devices have gradually killed off Symbian devices at Nokia ever since 2011, when the company first announced it would build devices exclusively for Microsoft’s mobile operating system. Nokia confirmed last month that it had already shipped its last Symbian phone so it’s not too surprising to see that last quarter’s Symbian shipments totaled zero. All the same, it’s still a remarkable end for an operating system that less than three years ago was still the most dominant mobile platform in the world. Asymco’s chart follows below.
