Facebook's Paper app -- which launched in 2014 -- was a unique, beautifully designed approach to displaying both articles and status updates in your news feed. Some even called it the future of reading news.
Paper was best known for its Instant Articles feature, which allowed users to browse and download articles from popular media outlets directly to their phones. It was also a convenient place to check Facebook messages and your timeline without switching apps.
But due to low user numbers, Facebook(FB) mostly used it as a testing ground to quietly roll out new features.
The social network shuttered the service on July 29.
