YouTube’s autoplay feature chooses and plays a follow-up video based on a viewer’s watch history. The article explains how to switch it on or off, noting that autoplay can suit people who use videos as background viewing but may also lead to more viewing and advertising.

On phones and tablets, viewers can use the toggle in the video player or open their profile settings and select Playback. On computers, the toggle is at the bottom of the player; on TVs and game consoles, it is under profile settings, and the choice applies to signed-in connected devices. Autoplay is off by default for users aged 13–17, supervised-account parents can disable it, and playback stops after 30 minutes on mobile data or four hours on Wi-Fi.
