KREM, virtual channel 2, is the CBS-affiliated television station serving the Spokane, Washington-Coeur d'Alene, Idaho market. It broadcasts its digital signal on UHF channel 20. The station is owned and operated by Tegna, and is operated in a duopoly with area CW affiliate KSKN (channel 22). The two stations share all back-office functions, and KREM produces a 10 p.m. newscast for air on KSKN. KREM can be seen in high-definition on Comcast channel 102 for the Spokane area, channel 1209 on Time Warner for the Coeur d'Alene area and for the Palouse, and channel 2 (both standard definition and high definition) for both Dish Network and DirecTV viewers.
KREM and KSKN are a part of a cluster of television stations in the Northwestern United States owned by Tegna, which includes KING-TV and its sister station KONG, Seattle; KGW, Portland, Oregon; and KTVB in Boise. All four stations provide material to co-owned Northwest Cable News, a regional 24-hour cable news service based in Seattle serving much of the region. KREM is the only non-NBC affiliate to be a primary contributor to NWCN, with the exception of KSKN and Seattle independent station KONG.
The station is also carried on cable systems in Calgary and Edmonton, Alberta, both of which are double the size of KREM's American coverage area. One result of this is that stations in Calgary and Edmonton air American shows on Pacific Time, even though Calgary and Edmonton are both on Mountain Time. It is one of five local Spokane area television stations seen in Canada on the Shaw Direct satellite service. It can also been seen on local cable systems in eastern British Columbia. Source
