The Wikipedia has the following information about this codepoint:

Parental controls are features which may be included in digital television services, computers and video games, mobile devices and software that allow parents to restrict the access of content to their children. These controls were created to assist parents in their ability to restrict certain content viewable by their children. This may be content they deem inappropriate for their age, maturity level or feel is aimed more at an adult audience. Parental controls fall into roughly four categories: content filters, which limit access to age inappropriate content; usage controls, which constrain the usage of these devices such as placing time-limits on usage or forbidding certain types of usage; computer usage management tools, which enforces the use of certain software; and monitoring, which can track location and activity when using the devices.

Content filters were the first popular type of parental controls to limit access to Internet content. Television stations also began to introduce V-Chip technology to limit access to television content. Modern usage controls are able to restrict a range of explicit content such as explicit songs and movies. They are also able to turn devices off during specific times of the day, limiting the volume output of devices, and with GPS technology becoming affordable, it is now possible to easily locate devices such as mobile phones. UNICEF emphases the responsibility of parents and teachers in this role.

The demand for parental control methods that restrict content has increased over the decades due to the rising availability of the Internet. A 2014 ICM survey showed that almost a quarter of people under the age of 12 had been exposed to online pornography. Restricting especially helps in cases when children are exposed to inappropriate content by accident. Monitoring may be effective for lessening acts of cyberbullying within the internet. It is unclear whether parental controls will affect online harassment in children, as little is known about the role the family plays in protecting children from undesirable experiences online. Psychologically, cyberbullying could be more harmful to the victim than traditional bullying. Studies done in the past have shown that about 75% of adolescents were subjected to cyberbullying. A lack of parental controls in the household could enable kids to be a part of cyberbullying or be the victim of cyberbullying.
