It doesn’t take long for iOS device owners to get their hands on the latest and greatest release of Apple’s mobile operating system. In what is pretty consistent with past releases 12% of iOS device owners are now running 7.1 after the first 2 days. After the first daythe rate was 5.9% according to Chitika’s numbers. “To quantify this study, Chitika Insights examined tens of millions of U.S. and Canadian iOS-based online ad impressions generated within the Chitika Ad Network from March 9 through March 11, 2014.” If you are wondering what the adoption rate is for iOS 7 then over the same three day period as the numbers taken above over 80% of the web traffic Chitika received was running iOS 7. Definitely impressive.
