One of the most annoying things about life online these days is autoplay. From ads that play audio on websites to previews on Netflix, videos that begin unprompted are, more often than not, a problem.
YouTube chooses the follow-up videos that play automatically based on your viewing history, so there's a decent chance that you'll be interested in watching what the feature bubbles up.
The more videos that the service shows you, the more ads it can run and the more it can pad parent company Alphabet's bottom line.
You can say no to autoplay in just a few steps.
One thing to bear in mind here is that if you have autoplay enabled, the next video YouTube has lined up for you won't automatically play if you type something, such as a comment or search, or if you scroll past the video player.
The easiest way to disable autoplay in the YouTube mobile and tablet app is to tap the toggle at the top of the video player while you're watching something.
Next up, let's take a look at how to change the setting on the YouTube app for TVs and game consoles. Go to your profile, access Settings and select the "Autoplay next video" option. Changing the autoplay setting here will apply to TVs and similar connected devices on which you've signed in with your account.
One other thing worth knowing is that if you're watching YouTube on a mobile network, autoplay will stop after 30 minutes.
