Facebook Messenger intros zippy Instant Articles preview within the Android chat app, iOS to follow
Starting with the Android app, and rolling later to iOS, Messenger will soon be offering Facebook's Instant Articles option directly in the chat thread. Instant Articles is the social network's answer to Google Accelerated Mobile Pages Project, which lets publishers design their news and media outlets to load up to ten times faster - ads, trackers and rich media notwithstanding.
You might have noticed Instant Articles as ones that load immediately directly in your News feed on Facebook, without having to open in a browser tab first, as Facebook itself hosts their content. Well, that same concept is now extended to Messenger - when someone sends you a link to an Instant Article (and a vast number of popular publishers are already taking part in the program), it will appear with a lightning bolt in the top right corner. Tap on the link, and the article will unfold directly into the chat thread to read immediately, just like the shared video clips now start playing right in Messenger. Neat, but we don't know if the opt-in encryption that is coming to Messenger will allow the Instant Article thingy just yet.
