Visualized: US smartphone market share, by manufacturer and platform, made pretty

They say a picture is worth a thousand words -- but in this case, a picture is worth tens of billions of dollars in market share. Nielsen has broken down its US smartphone market share stats between November and January in two dimensions -- by market share and by platform -- and stuffed all that data into a single block of mesmerizing color. It's interesting to see the Apple and RIM juggernauts flanked by two imposing, red slivers of HTC, isn't it? The research firm also took a look at platforms by age group; the shares are surprisingly consistent across the board, though Android does have a slight edge with the young'uns. Follow the break for that chart.
