Led by the iPhone, smartphone usage is up 193% year-over-year (in absolute terms), according to a new report from mobile ad network AdMob (which was purchased by Google this fall, though the sale
is pending FTC review). As a result, AdMob reports that its traffic grew from 35% to 48% from February 2009 to February 2010. Meanwhile, use of "feature phones" -- like most Samsung, Nokia and LG
phones -- was up 31% during the same time period, yet their share of AdMob's traffic fell from 58% to 35%, according to CNNMoney.com's Apple 2.0 blog.
Also of note -- particularly with iPad's release date nearing -- usage of mobile Web devices (chiefly the iPod touch, but also connected game systems like the Sony PSP and Nintendo DSi, was up a whopping 403% in absolute terms as their traffic share grew from about 7% to 17%.
