Watershed (broadcasting)
In broadcasting, the watershed (or safe harbor) is the time of day after which programming with content deemed suitable only for mature or adult audiences is permitted. In the same way that a geological watershed divides two drainage basins, a broadcasting watershed serves as a dividing line in a schedule between family-friendly content and content deemed suitable only for a more mature audience, such as programs containing objectionable content; this can include graphic violence, strong language, and sexual content, or strong references to those themes, even if they are not shown explicitly.
