It's nice that a YouTube Red subscription gives you ad-free and offline viewing, but wouldn't those features be more useful for keeping your kids entertained on your next vacation? YouTube agrees. You can now sign in to Red through the YouTube Kids app, giving junior viewers all the benefits without making them visit grown-up apps or sites. They won't see promos while watching their favorite show, and they can keep playing when they're stuck in the back of the car for a few hours. If they're music fans, they can switch apps while their tunes play in the background. You probably won't subscribe just for the Kids support, but it's a strong incentive for families.
