Content restriction refers to the practice of limiting access to certain information or media based on specific criteria. This can include age restrictions, geographic limitations, or content that may be deemed inappropriate or harmful. Organizations, governments, and online platforms often implement these restrictions to protect users or comply with legal regulations. Common examples of content restriction include parental controls on streaming services, which prevent children from viewing mature content, and censorship by governments that block access to certain websites or information. These measures aim to create a safer environment for users while balancing the need for free expression.
