The 7-9am block was pretty much identical for all the stations as the 6am hour. The thing that's a little shocking to me about the LA ratings is just how low the share is across the board – so much competition I guess, not just from all the other news options, but just everything else that's on the air too. I can't see the Spanish stations, but maybe those take most of the viewers, perhaps?
I suppose you could say that KTLA and KABC are the leaders, but neither of them seem to have anything that's a dominant news hour over everyone else like what you see in other markets. KTLA stays a pretty constant .5 rating / 12 share in the demo all morning long, which isn't bad, but not a runaway. Compare that to the Bay Area market, for example, where KTVU averaged a 1.0 rating / 23 share in the 7 and 8am hours.
Another insight I saw is that I can see why they'd want to do more with KCAL. The primetime block is actually quite strong. KCAL's 9pm hour last week averaged a .6 rating / 4 share in the demo, which was not only the best rating of any KCAL/KCBS newscast, but also one of the better ratings of any English language newscast in LA.
I think trying to do something local on KCAL in the morning while leaving all the network garbage on KCBS is a pretty good idea. That doubles the ad inventory, and it at least gives them a chance at maybe siphoning some viewers away from KTLA and KTTV. What KCBS is currently doing in the morning clearly isn't working.
