The PBS affiliate for Long Island, with a transistor in Plainview and offices in Garden City. Since it is in the same market as the much larger WNET, based in New York City, it is significantly smaller financially and in terms of viewers, since the two stations are already sharing a limited amount of the television audience. WNET tends to air more "eat your vegetables" programming, such as science and arts documentaries that you know are intelligent, but can't hold your attention for long. WLIW tends to air more sitcoms and dramas from the BBC, including such viewer favorites as "Eastenders", "Inspector Morse", and "As Time Goes By", among others.

It is also famous for the old films shown late on Saturday nights. These films are the old black and white versions that are gritty and dark, yet dignified classics in their own right. Films shown have included "The Hunchback of Notre Dame" and "Cyrano de Bergerac".
