As part of the service, Google says, "Readers who purchase from a One Pass publisher can access their content on tablets, smart phones and websites using a single sign-on with an email and password. Importantly, the service helps publishers authenticate existing subscribers so that readers don't have to re-subscribe in order to access their content on new devices" Google One Pass is available for publishers in the U.S., the U.K., Canada, France, Germany, Italy, and Spain.
But Apple has one critical advantage over Google. The App Store has tremendous traffic from owners of iPhones and iPads. There are over 160 million devices that run on the Apple iOS system. Google does not have a comparable and ready customer base because its Android mobile OS is used by hardware companies over which Google has little control. Google's Apps MarketPlace is smaller in both the number of offerings and downloads than the Apple store.
Google's new project may be more favorable financially to publishers, and may have other benefits for consumers, but the search giant's application "ecosystem" may not be powerful enough to support a robust online subscription service. Apple does not have such a problem.
