WCSH (channel 6) is a television station in Portland, Maine, United States, affiliated with NBC and owned by Tegna Inc. The station's studios are located on Congress Square in Downtown Portland, and its transmitter is located on Winn Mountain in Sebago. WLBZ (channel 2) in Bangor operates as a semi-satellite of WCSH. This station clears all network programming as provided by 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 WCSH and WLBZ 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. History WCSH-TV signed on December 20, 1953, from studios at the Congress Square Hotel in downtown Portland. The station was owned by the Rines family through their Maine Broadcasting System; the family had built the hotel in 1896, and established WCSH radio (970 AM, now WZAN) on the top floor in 1925. It has always been an NBC affiliate, although during the late-1950s, the station was also briefly associated with the NTA Film Network. In 1958, the Rines family acquired WTWO in Bangor from Murray Carpenter, and renamed it WLBZ-TV (after WLBZ radio, now WZON, which the family had owned since 1944). Although the two television stations were now sister stations, they remained completely separate entities. At various points, the Maine Broadcasting System also included WRDO radio in Augusta and KMEG in Sioux City, Iowa, with WCSH-AM-TV as its flagship. Sometime in the late 1950s, WCSH-TV signed on W73AB, a repeater on channel 73 in Littleton, New Hampshire. It is unknown when it went off the air, but the latest record of its existence is from 1963, and it would have had to cease operations by 1983, when channels 70–83 were removed from broadcasting. In 1977, WCSH-TV moved to new facilities across the street from the hotel at One Congress Square, where it remains today. The radio stations were sold off in 1981; in 1997, the -TV suffix was dropped. In the mid-1990s, WCSH added a website providing 24-hour news and weather coverage outside newscasts.
