By all reports, CN/AS is using the new hour for that Rick and Morty Show and King of the Hill. The PTC can whine all they want to but fact is they're not putting anything at 8pm that's any more extreme than what airs currently on the broadcast stations.
I have to say people's reactions on this board are ridiculous. Adventure Time and Regular Show air at 7pm already, so it's likely that Uncle Grandpa and Steven Universe will both scootched in with them at 7:30 and 7:45. They've done well on CN, so they're not getting canceled.
And Adult Swim is NOT going to expand to 7 or 6 o'clock. You can't use Jetix and Disney XD as a precedent for this.
Seriously, all that's going to happen if some of the Monday lineup will end up airing sooner, nothing is getting canceled for this. So what exactly is the problem? What difference did CN or AS having 9pm really make anyway? CN would have just used them for reruns for Adventure Time and/or Regular Show; all of you would just eventually complain about CN needing to air something different anyway.
And I'm not even going to dignify the ludicrous thought pattern of Western Animation somehow "dying" because of Cartoon Network giving Adult Swim one extra hour with a response.
It's not stupid if AS has been doing well enough and if the advertisers are demanding it. Advertisers are the real customers of TV networks not the viewers.
And by what definition are their ratings "undeserved"? You not liking them?
