Must be noted that the decision to move back to a 7pm finish probably wasn't CBBC's decision to make.
And of course many other children's channels are pretty much 24/7 now, so its sort of a halfway house.

Anyway I'd suspect there are are more complicated issues around shoving "all kids content past and present" on ITVx. It will probably cost money at the very least, and of course ITV don't actually own a lot of it anyway (going back to the earlier discussion, Art Attack on ITVx won't be an option without chucking a load of money at Disney).

Nobody suggested Art Attack would be on ITVX - the suggestion was that it'd be on Disney+.

And yeah, CBBC reverted to a 7pm finish because BBC Three came back on air. Their channel controller would've had no say in that decision.
