WLBZ (channel 2) is a television station in Bangor, Maine, United States, affiliated with NBC and owned by Tegna Inc. The station's studios are located on Mount Hope Avenue in Bangor, and its transmitter is located on Rider Bluff in Holden. Although identifying as a separate station in its own right, WLBZ is considered a semi-satellite of sister station WCSH (channel 6) in Portland. WLBZ's master control, as well as some internal operations, are housed at WCSH's studios on Congress Square in Downtown Portland. WLBZ clears all network programming as provided through its parent, simulcasts most of WCSH's newscasts (with local weather inserts) and airs most of its syndicated programming (though in some cases at different times). There are also some programs that only air on WLBZ while some are only seen on WCSH. WLBZ also airs separate station identifications and commercial inserts. Although WLBZ and WCSH are based in different locations and technically serve separate markets, the two essentially operate as one station. With their combined resources, the stations provide statewide coverage not offered by any other outlet in Maine. WLBZ previously served as the default NBC affiliate for the Presque Isle market, which did not have an affiliate of its own. It is carried in the local tier of Spectrum's cable system in Presque Isle, and is also offered as the NBC affiliate in the Presque Isle Dish Network and DirecTV channel lineups. This changed in 2020, however, with the sign-on of NBC affiliate WWPI-LD by CBS/Fox/CW+ affiliate (and sister station of rival WABI-TV) WAGM-TV. In addition to its main signal, WLBZ operates low-powered digital repeater WGCI-LD on VHF channel 4. Licensed to Skowhegan, this station has a transmitter in Norridgewock's Larone section. History The station began broadcasting on September 12, 1954 as WTWO (sometimes rendered as "W-TWO"), an independent station locally owned by Murray Carpenter. The following January, it began carrying some CBS programming, becoming a full affiliate by September 1955 (prior to this, CBS programming was seen on WABI-TV (channel 5), which became a primary NBC affiliate). In 1958, WTWO was sold to the Rines family's Maine Broadcasting System, owner of WLBZ radio (620 AM), WCSH-AM-TV in Portland, and WRDO in Augusta. The new ownership changed the station's call letters to WLBZ-TV that June to match its new radio sister (which the Rines had owned since 1944). (The WTWO calls now reside on the NBC affiliate
