As of that time it offered four separately-subscribable selections of PBS programming in the United States, "PBS Documentaries," "PBS Living" (also on Apple TV), "PBS Masterpiece" (also in Canada) and "PBS KIDS". In the UK, a "PBS America" documentaries package is available on Amazon Prime Video. On September 3, 2020, PBS began to offer a livestream of their member stations for free via its website (as well as the websites from the member stations), on smart TVs, and on their mobile apps. However, only a small handful of stations currently do not have a livestream of their stations set up. Jefferson Graham of USA Today called it, "Arguably the best bargain in streaming."
