In the UK and Ireland, the Toons part of the logo is yellow. There are also other versions where Toons is in a different color. Also, the UK and Ireland versions don't run 24 hours a day.
After 2 a.m. (Eastern), Nicktoons switched from split-screen credits to regular credits until the mornings. An hour of SpongeBob episodes aired at that time on Wednesday and Saturday nights continuing from a marathon that began at midnight (Eastern), with its original unplastered credits intact. Before Nicktoons became ad supported and rebranded into Nicktoons Network in 2005, there were no split-screen credits intact at all yet.
May 5, 2014 after Nicktoons rebranded again with a new style, with the rebrand also including the addition of on-screen credits, just like its main sister channel Nickelodeon. This ended the daily 2 a.m. Eastern regular credit routine.
Somewhere around 2015, in the UK and Ireland, Nicktoons URL appeared 1 or 2 mins later till the show ended!
