WNLO (channel 23) is a television station in Buffalo, New York, United States, serving as the local outlet for The CW.

It is owned and operated by network majority owner Nexstar Media Group alongside CBS affiliate WIVB-TV (channel 4).

In 1992, many cable providers in Hamilton and Niagara began carrying WNEQ-TV, displacing long-standing WQLN from Erie, Pennsylvania, in the process.

One year later, Rogers Cable began carrying WNEQ on its digital tier for customers in the Greater Toronto Area.

LIN TV (owner of CBS affiliate WIVB-TV) wanted to buy WNEQ-TV and run it as a commercial station.

Consequently, the Buffalo market retained an educational-licensed station and LIN TV was permitted to purchase the converted-to-commercial WNEQ-TV.

In 2005, Rogers submitted a successful request to the Canadian Radio-television and Telecommunications Commission (CRTC) to allow carriage of WNLO in Ontario.

On November 2 of that year, WNLO began broadcasting CW network programming in high definition on its digital signal.

In 2015, WNLO acquired Raycom Sports's ACC Network package of college football and men's basketball broadcasts from the Atlantic Coast Conference.

In April 2019, WNLO announced the acquisition of a package of Buffalo Bisons Minor League Baseball games, mostly on Saturday nights, once approximately every two weeks.

[15] After WIVB-TV took over operations of WNLO in March 2001, the CBS affiliate began producing a nightly half-hour prime time newscast on channel 23.

In order to gain more viewers than WNLO, the second WGRZ 10 p.m. newscast originally featured ten minutes of news and weather, with the rest of the half-hour dedicated to sports.

In the summer of 2019, WNLO/WIVB shifted to its post-transition channel, and began to transmit from the WIVB-TV Tower in Colden, and merged the two stations' operations fully together, including physical transmitter.

TWC had initially refused to accept these fees and, on October 2, WNLO and sister station WIVB-TV were removed from the provider's lineups.

As part of the agreement, WNLO's high definition signal began to be carried on TWC's digital tier for the first time.
