Each local PBS station is free to choose which shows to broadcast and when to schedule each. For specific shows, dates and times, viewers should check their local listings through a service such as TV Guide, in their local newspaper or at PBS.org.
The Public Broadcasting Service has more than 350 member stations, as of 2015. Local stations are typically operated by non-profit organizations, local authorities, state agencies or universities. In certain markets, PBS may operate multiple member stations, each licensed to a different entity.
PBS is a distributor of programming to local public television stations. PBS provides series such as NOVA, PBS NewsHour, Sesame Street, Masterpiece and Nature to its member stations. Public television stations may also purchase shows from third-party sources, including other member stations, American Public Television and independent producers.
