Facebook debuts video playback changes, including autoplaying with sound unless device is muted, picture-in-picture video, and rollout of vertical video format
People are watching and sharing more video on Facebook than ever, and we're focused on continuously improving the video experience.
Context & Ripple Effects
This announcement is the payoff of a long runway: Facebook spent 2016 running mobile tests of sound-on autoplay behind a settings toggle, and had already tuned its feed in 2015 with ranking signals that rewarded activating audio and watching full screen. Making sound the default unless a device is muted converts those experiments into platform policy.
The same update ships picture-in-picture and a vertical video format — early moves in a redesign arc that later produced a TikTok-style vertical player for Reels, Live, and longform and, per later reporting, plans to test a full-screen immersive player replacing the newsfeed on app open.
First-order effects
- Advertisers and publishers lose the silent-autoplay assumption overnight: sound-on delivery raises production requirements and inflates view counts relative to the muted baseline, changing what 'a view' is worth.
- Users gain picture-in-picture multitasking and native vertical playback, reducing friction that previously pushed them to other apps for those formats.
Second-order effects
- Because feed ranking already rewards audio activation and full-screen viewing, sound-on autoplay feeds more of exactly the signals Facebook optimizes for — a feedback loop that shifts distribution toward video over text and photo posts.
- Rivals competing for the same watch time face pressure to match default-sound and vertical experiences, accelerating format convergence across social feeds.
Third-order effects
- If the pattern holds, the News Feed itself becomes a video surface: the trajectory from this update runs through Watch Party's shared viewing to a full-screen immersive player replacing the feed on app open — a structural shift from scrolling content to a broadcast-style viewer.
The trend: Facebook has been steadily converting the News Feed from a muted text-and-photo scroll into a default-sound, full-screen video destination, with each playback change normalizing the next.
