WNYZ-LP was a low-power television station licensed to New York City, owned by the Island Broadcasting Company. WNYZ's television signal was broadcast in analog on VHF channel 6. It had transmitted a digital signal over channel 6 with a virtual channel of 1.1.
Programming consisted of Silent Films starring Charlie Chaplin and Buster Keaton. The station aired this programming without commercials. Viewers could hear the audio of WWRU in Jersey City, which is likewise intended for the radio audience listening on 87.7FM.
During most of its life while operating on channel 6, the station has been operated more as a radio station than a television station. WNYZ-LP broadcasts video, usually silent movies which are repeated throughout the day, for the likely reason to fulfill the Federal Communications Commission (FCC) requirement that some sort of video be broadcast on the frequency because WNYZ-LP is licensed as a television facility.
WNYZ-LP was the last remaining analog television station in New York City.
