The website used data provided by ad exchange MoPub to contradict an earlier report by Chitika which said that Google Maps release had no significant impact on iOS 6 adoption.
MoPub monitors over 1 billion ad impressions a day across more than 12,000 apps and a dozen ad networks, making its data set more reliable than individual ad network Chitika. MoPub provided TechCrunch with data showing a 13 percent increase in iOS 6 users just from Monday to Wednesday, indicating many people switched to the newest Apple mobile firmware as soon as Google Maps' standalone app arrived in the App Store.
The remaining increase was likely delayed until the weekend and therefore not seen in Chitika's data because people wanted to wait for positive reviews of Google Maps for iOS 6, or they didn't have time to do the lengthy OS update and stare at a loading bar during the work week.
Google released Maps for iPhone around 11pm EST on December 12. On Monday, Jeff Huber, Senior Vice President, Commerce & Local at Google, revealed via his Google+ page that the app had been downloaded over 10 million times in the first 48 hours. (downloaded over 10 million times)
