The bulk of the work was in updating our "navigation": the little idents between shows telling you what's coming up after the break.
Nick UK *loves* them. They exist in a bunch of variations based on what's happening around a break -- is more of the same show next? Something else? Is it a premiere or a rerun? And so on.
We don't often place these by hand, our scheduling software does it for us. But someone has to tell the software what to do. For every scenario possible.
