PBS

PBS is the flagship service of American public television, a non-profit network launched in October 1970 and owned collectively by its member stations. Its schedule is built around education and culture: acclaimed documentaries such as Nova and Frontline, the PBS NewsHour, Masterpiece drama from Britain, and children's programming that has included Sesame Street for generations. Rather than a single national feed, PBS reaches viewers through hundreds of local member stations, each adding regional programming of its own. The service is free over the air across the United States. The official website, pbs.org, carries schedules, station finders and authorised streaming information.
