Facebook crowed Tuesday that an Android version of its Messenger app has been downloaded more than a billion times from the Google Play store. Other than Facebook, only Google boasts apps with more than a billion Google Play downloads onto Android-powered mobile devices, according to technology news website TechCrunch. A chat forum on Messenger's page at Google Play was rich with accolades but peppered with comment that the high download count was driven by Facebook spinning the widely used service out of the social network, compelling people to get the app. Facebook last year broke off Messenger from the main Facebook application for mobile users, creating a separate platform that claims more than 600 million users.
