You might have heard: Facebook Instant Articles launched in May with nine publishers including NYT and BBC News

But did you know: Following the buzz around the launch of Facebook’s Instant Articles, no new articles have been published since May 13. Facebook never offered a concrete timeline for its rollout of Instant Articles, but it has said it wants to use feedback from the first group of publishers to make improvements to its guidelines and format. When publishers signed on to Instant Articles, they did not commit to run a specific number of articles.
