The Spokane TV market is pretty good for its market size, #73 at last check. Keep in mind that Spokane is the "go-to" U.S. market for most of Alberta, Canada including the big metros of Calgary and Edmonton. (I remember a time when the Spokane stations sometimes gave the weather conditions for those cities, but that seems to have gone away).
Here are my thoughts:
KREM (CBS) Channel 2 (owned by Tegna): Good principle anchors, Mark Harahan (previously in Portland), and Jane McCartney (previously in Seattle), make a good team. Graphics/Music are the standard Tegna format with the "upcoming crawl". Set is good, news style is similar to KING in Seattle.
KXLY (ABC) Channel 4 (owned by Morgan Murphy Media, same as KVEW/KAPP TriCities/Yakima): Nadine Woodward the principle solo anchor (I've always thought she is good, but would be even better with a good co-anchor). Graphics/Music/Set standard but a bit dated. Very middle of the road news style.
KHQ (NBC) Channel 6 (owned by Cowles Company, same as NBCRightNow Yakima/TriCities): Principle anchors are Dan Kleckner and Stephanie Vigil, both very solid. Kleckner has been with KHQ for decades. Graphics/Music same as NBC Yak/Tri. News style like its competition, very middle of the road.
KAYU (Fox) Channel 28 (owned by Northwest Broadcasting): News operations produced by KHQ.
All in all, a decent tv market IMO. Everyone seems to be doing quality newscasts, though nobody is hitting it out of the park. (I do not have access to ratings, but KHQ has been near the top over the years).
