I don’t watch TV at all (not a snob thing; my computer feeds me plenty of idiot stuff) but I do read the local stations’ news sites for coverage of various topics.
WFAA is Dallas’ ABC affiliate and partners with the DMN. It’s independently owned along with a UHF counterpart (KFAA), making Dallas the largest major media market to have an independently-owned station broadcasting one of the “big four” network feeds (ABC, CBS, NBC, Fox). I subscribe to their politics feef and regularly see other platforms like the Texas Tribune linking to them. I feel like they’re pretty reliable for coverage and they regularly have details that other outlets don’t get.
KERA is also the name of the local PBS television station as well as the NPR radio affiliate. As I mentioned last week, I find them very reliable.
KXAS, aka NBCDFW, is the local NBC affiliate. I see links to them occasionally and find them in google searches for various local news topics. I don’t have a strong opinion about them either way.
KTVT and KTXA are two branches of the CBS network in Houston, both owned by the network. Their news site links back to the Texas directory of the national CBS site. I don’t see them linked very often and I don’t have a strong sense about their local coverage.
KDFW aka “Fox 4” is the local Fox affiliate; it was originally owned by the now-defunct Dallas Times-Herald and passed through various hands including many years as a CBS affiliate. Fox has owned the station since 1996. I don’t seek out their coverage but occasionally I see links to them or find something that nobody else has when I’m googling for local stories about a specific topic. They’re not national Fox news, but I’m just a little wary of them as a source.
