You don’t have to be a business guru to know the smartphone market is getting more crowded all the time. Recent shipping numbers from the global market research firm IDC bring that story into sharper focus.

Microsoft’s Windows phone nudged its way past BlackBerry to claim third place during the first quarter of 2013. Shipments of Apple’s iPhone are slowing down — representing 17 percent of all smartphone shipments, down from 23 percent this time last year. Meanwhile, Android shipments have nearly doubled since the first quarter of 2012.

Fortune Magazine’s Adam Lashinsky joins Marketplace Tech host Ben Johnson to discuss the details behind the numbers and where the market is headed.
