Facebook is now an app store.
iPhone and iPad users running iOS6 can now download apps by clicking on Facebook ads. Facebook’s app store will appear in a separate dialog box; once the app installs, users can pick up where they left off. They were previously redirected to Apple’s app store.
The new feature is a big step in prolonging the user experience and, crucially, getting mobile users to click ads, which is a big part of Facebook’s future financial future.
