WNLO, virtual channel 23 ( UHF digital channel 32), is a CW- affiliated television station located in Buffalo, New York, United States. The station is owned by Media General, as part of a duopoly with CBS affiliate WIVB-TV (channel 4). The two stations share studios on Elmwood Avenue in Buffalo, WNLO's transmitter is located on the eastern side of Grand Island. However, master control and some internal operations for both stations are based at hub facilities within sister station WISH-TV's North Meridian Street studios in Indianapolis, Indiana.
The station can be considered an alternate CBS affiliate as it simulcasts the CBS Overnight News and the CBS Morning News from WIVB-TV. The station is also responsible for airing CBS programs when WIVB-TV is unable to or otherwise chooses not to air a program due to local or syndicated programming commitments. WNLO is not available in portions of Cattaraugus County that are served by Atlantic Broadband, where WSEE-DT2 out of Erie, Pennsylvania is used as a less expensive alternative.
