At F8 this week, Facebook announced that Instant Articles are now available for all publishers. While this didn’t get as much buzz as drones, 360 cameras, or bots, this release marks the beginning of a major shift in media as we know it.

Until now, Instant Articles have been restricted to a few dozen top publishers. In case you’re not familiar, these are articles published directly to Facebook which users can read without leaving the native Facebook App. The benefit is a cleaner, faster, and more uniform experience that users love.

As we wrote last week, publishers must adapt to this new distribution paradigm or face declines in their readership and monetization. Many major publishers have already begun expeirmenting with Instant Articles, unable to ignore the opportunity because of how much of their traffic already comes from Facebook. As users spend more time within the walled gardens of social networks, competing for attention in the News Feed is increasingly complex and zero sum. Publishers who don’t offer Instant Articles may see their content deprioritized relative to their competititors.

Adoption has been comparatively slow as these initial top publishers cautiously tested the program. However, Instant Articles are poised to gain rapid adoption across sites of all sizes with this general release. There are two forces driving this: competitive pressure and ease of integration.

Ease of Integration

It is now frictionless for even long tail websites to integrate with Instant Articles. For starters, there are WordPress and Drupal plugins, making it easy for CMS integrations to take advantage of this new format. WordPress alone represents  over 75 million websites as of 2014, and Drupal represents 12% of the top 100,000 websites. Medium has also announced that they’ll be releasing Instant Articles support in the coming weeks.

Competitive Pressure

Facebook has never directly indicated that Instant Articles will be prioritized over traditional links in the News Feed. That said, the platform rewards low abandonment, high user engagement, and happy users, all of which are clear benefits of the new format. Instant Articles will quickly reach critical mass, with publishers unable to compete if others in their categories are publishing directly to Facebook. No one who relies on Facebook for traffic (i.e. every publisher) will be able to resist once the format gains momentum.

Facebook has ensured support from the largest CMS tools (WordPress and Drupal), the modern alternative to these options (Medium), and the top publications in the media landscape. Facebook is deepening their hold on media distribution and encountering little resistance in doing so. It’ll likely be only a matter of months before the majority of mobile content you see on Facebook is presented without ever leaving the app.
