It was *a lot of work* even though most of the work was already done.

Nickelodeon US was the first to rebrand as that's what all of this was designed for in the first place. Then Nickelodeon Italy followed on July 3rd.

I'll let you in on a little secret: Nick Italy sits one desk away from me at work.
My colleagues there did the bulk of translating U.S. assets (60p/30i Full HD or 4K) to 'rest of the world' standards (50p/25i) and testing technical functionality on our playout systems.
