I would agree that KWWL is likely to stay very strong. They started this back in the early 70s when they started to win the 10pm timeslot over WMT TV- (Grant Price's arrival helped, and being the lead in to Johnny Carson didn't hurt either).
In the late 70s channel 2 tried "wacky news" with Bachmann, Bailey and Bremer. That didn't work. Craig Johnson didn't really want to play 2nd bannana to the weather dork, er, duck and jumped to channel 7 when Jym Ganahl left. Dave Towne came in about this time. Channel 2 kept playing with their anchor line up- "Dave Shay and Maggie Jensen are our team" then it was "Dave and Maggie who?". They then revamped the entire team and dumped everyone. They have kept this up ever since.
One thing Channels 7 and 9 learned is that people like familiar faces on the newscasts in these smaller markets, especially the lead anchor and the weatherguy. That's why 7 kept Ron and Craig and 9 kept Ron and Denny. People want to trust their newscasters and meteorologists.
Channel 2 seemed to operate like an old Mickey Rooney / Judy Garland shop "Hey gang let's put on a newscast" and rotated anchors and weathermen like it was an "American Idol" contest. You don't build any audience loyalty when you keep driving people out.
KGAN had a real shot in the late 80s and 90s and had some real talent there, but they still seem to attract people in dire need of a N Frank Magid makeover. I am hopeful for some of the new folks I have seen and quite frankly putting Dave Towne on the air would add a level of trust (cause he has been around so long).
The new reporter Bigad Shaban has a good delivery style and presence - and a decidedly unique name. Molly Nicholsl who does the noon news needs either bangs or bushy eyebrows as she has way too much forehead. Erica Cervantes over elocutes every sylable, but is a pleasing presence otherwise.
Congratulations to Cary J Hahn for his Jack Shelly award.
The station has been increasing it's coverage of northern Iowa, a lot more of Waterloo and Dubuque news, I'll give the new ND a chance, so far it looks like they are trying to rebuild.
