A captive audience is a person or group of people forcibly subjected to view or hear expression in the use of places where they are reasonably unable to avoid seeing or hearing the expression.
The "captive audience" doctrine is the belief that in certain places, individuals have a right to avoid offensive speech. Therefore, it serves as an exception to the First Amendment rights of artists-- but only in some locales.
A person's home is the primary environment where courts have said that a person has the right to "shut herself up in her own ideas." Hynes v. Mayor of Oradell, 425 U.S. 610 (1976).
Other places where the captive audience doctrine has been applied are public transportation and workplaces. However, not all jurisdictions agree as to what types of places an individual may be "captive."
