If you’re looking to restrict YouTube on your TV, there are a few steps you can take. Depending on the type of television set you have and its capabilities, there might be some additional options available to you as well. The most straightforward way is through parental controls that limit access to certain types of content. This restriction will apply across all apps and services, including YouTube. You can also install an app like K9 Web Protection or NetNanny for TVs that come with AndroidTV operating systems which allow for more focused control over what content is allowed online and accessed via streaming platforms like YouTube. Additionally, if your TV has built-in profiles or user accounts, each profile could be assigned different levels of restrictions so people in the household can all use it but only see age-appropriate content based on their profile settings. Finally, many smart TVs offer pre-installed filters such as those from Common Sense Media which rate videos according to age appropriateness - this would ensure no one in the family sees unsuitable material regardless of their profile settings or account usage history. Taking these steps should help keep everyone safe while still allowing them access to all their favorite shows and movies without having to worry about inappropriate material showing up unexpectedly!
