Android ‘surges’ overseas, declines for first time in U.S. by Philip Elmer-DeWitt @FortuneMagazine August 8, 2013, 10:53 AM EST E-mail Tweet Facebook Google Plus Linkedin Share icons Source: Asymco.com FORTUNE — Pity the poor headline writer trying to make sense of Wednesday’s smartphone market share reports. On the one hand, you have IDC reporting that Apple AAPL “ceded” market share last quarter as Google’s GOOG Android “surges,” generating this from the Wall Street Journal: Android Obliterates Smartphone Market On the other you have comScore reported numbers showing that — for the first time since it appeared in a smartphone in 2008 — Android ended the quarter with fewer users in the U.S., giving Asymco’s Horace Dediu an opening to write: Signs of US Android net user decline Both headlines can be correct, of course. It wouldn’t be the first time America has pulled one way and the rest of world another. What’s harder to say — and not easy to reduce to a snappy headline — is whether the U.S. is leading indicator for the worldwide smartphone market, or just a special case.
